Yep, that sounds about the same. Strange that the vid card would stop the whole thing booting, but hey, now I’ve seen it with my own eyes! Sadly, the magic was only short lived. It works for a bit and then fails in a similar fashion or by showing video artefacts which then crashes the machine anyway.

Yet, annoyingly enough, if I pull the thing apart again and just reseat the VGA connector just above the keyboard, all is well again. I can’t work out exactly what’s wrong because the slightest pressure or movement causes it to fail.

Device Name: SoundMAX Integrated Digital Audio. Driver Date, 2005-03-28, File Size: 113.01K. Driver Version: 5., Vendor: Analog Devices. Supported OS: Windows 10 32 bit, Windows 8.1 32bit, Windows 7 32bit, Windows Vista 32bit, Windows XP. Aug 26, 2006 Hi Everyone- My laptop display is horizontally stretched. Not just the wallpaper but anything I pull up on the screen. It is only stretched in the horizontal d.

Its a few years old now but hasn’t been dropped off a cliff recently so what gives? VERY annoying, any other suggestions apart from a hammer or super glue?!?!?:-p •.

Hi, My Dell Inspiron 9300 refuses to boot on AC adapter, with or without battery installed! The brief history of the laptop is as follows: I bought the laptop a little bit longer than one year and a half ago. Last year, I accidentally spilled water on it.

It shut off by itself, but somebody turned it on immediately, it shut off by itself again. Then it won’t boot. I took the laptop apart, blew dry all the parts, and put them back together. It boots, but only when the battery has power in it AND the AC adapter is NOT plugged in. Isn’t that weird?!

Last week, the laptop was off when I came back home (it was on when I went out). I found the light on the AC adapter was off by itself, and then the battery was drained. That was why the laptop was off. But I really had a very hard time turning it back on. Somehow the battery had a little power left, just enough to turn it back on, and within literally a second I plugged the AC power in and started charging the battery. Now the laptop is working again.

But I am very annoyed by the fact that if the battery goes bad eventually, the laptop will be useless. Can someone please give me some hint? What possibly went wrong? How can I fix it? Thanks a lot! Your site is excellent, I just discovered it via google and it’s very very helpful.

Question ->brother broke the 1, 2, alt, ctrl,?, and I key. Many of the parts are lost. I took it to the shop, but since I’m overseas, they were very unexperienced, and weren’t quite sure what to do, told me I’d have to buy an entire new laptop keyboard similar to it for 1000 sr, which is really really expensive and won’t come for 2 weeks, I dunno what’s the deal. Also, super glue spilled on the underside of the I key which remained exposed cause the actual key is gone – which, although I attempted to remove it with acetone, I couldn’t get a hold of the acetone till the next day, and it was already dried and ruined, now the key requires an extra push when typing and has a lot of friction, which is super irritating and inefficient. Is there anything else I could try or should I just take the plunge and put my precious laptop in these guys’ hands? It’s still under warranty, but the warranty isn’t honored in a different country, only the country you bought it in, unfortunately. Thanks for any help, much much appreciated =) •.

I have just had a Compaq Presario M2000 handed to me with the words “it doesn’t work”. With both the power cable plugged in and not plugged in, it doesn’t boot. It has power as indicated by the power light, but that is all it does, power on. There are two leds blinking, one above the scroll [num lk] button and one next to the caps lock button. The hard drive does not power on, and the DVD ROM acts like its going to then stops, and repeats this over and over.

It initially beeped twice when it was first powered on, but after removing and reseating the ram that stopped. As it sits right now there is nothing but one stick of ram in it, no HD, no DVD, the needed hardware to get it started. I’m stumped at this point. Also odd note, compaq says these are all intel, but this one has a Mobile Sempon Sticker on it. I HAVE A PRESARIOV5000 AND I’M HAVING PROBLEMS WITH MY LAPTOP TURNING ON.

LAST TIME I WAS USING IT IT WAS WORKING JUST FINE AFTER I WAS DONE I TURNED IT OFF LIKE I USUALLY DO. WHEN I CAME BACK FROM WORK I FOUND ONE OF THE PROCESSOR ORANGE LIGHT ON.

I THOUGH I HAD LEFT IT ON AND TRIED TO TURN IT OFF BUT IT WOULDN’T RESPOND TO ANYTHING I TRY DOING. I TRY REEBOTING, CHANGING MEMORY CARD DIFFERENT BATERIE AND OTHER TROUBLESHOOTING GUIDES BUT NOTHING SEEMS TO WORK. IF SOMEONE KNOWS A RESOLUTION TO MY PROBLEM I WOULD APRECIATE ANY HELP I CAN GET. My daughter’s HP Pavilion zt1290 had a failed solder joint where one of the pins of the ac adapter connector goes into the motherboard.

I re-soldered the connector, but now the machine won’t boot. Thanks to learning a bit from your site, I tried to systematically find out what was wrong. Here are a few of the things I tried & the symptoms that resulted: 1) Tried to boot with only the motherboard, the screen, the processor heat sink, the fan, and the power adapter.

At this point, the memory modules were the only other thing plugged in. Result: Fan starts up for 5 seconds or so, and turns off.

2) Reset the system using a paper clip, as the HP manual suggests. Result: Same as 1).

3) Added the optical drive with the XP system disk inserted. Result: The fan & screen behave as in 1), but the drive starts up & runs for a while (perhaps a minute – I didn’t time it), and seems to be seeking occasionally, based on the noise I could hear. Then the drive stops also. 4) Removed optical drive and tried all the possible configurations of the 2 memory modules, one at a time in each of the 2 memory slots, and both in, but each in the opposite slot from where it had started.

Result: Same as 1). 5) Tried 1), 2) & 3) with an external monitor plugged in the VGA out port (with the laptop’s display still connected). Result: Same as 1) & the external display stays blank. Result: Same as 1). 6) Playing around with the configurations, I noticed that the status LCD display on the front edge of a laptop would show the time. I started trying the buttons for the status display on the front edge and found that with an audio CD in the optical drive, I could get the display to show that it was trying to play the CD.

That is, for example, to display would show it going to the first track and would start timing, as if it was playing the track. The buttons would allow me to switch tracks, and start/stop playing, at least according to the LCD display. The CD itself with spinning in the drive. I tried putting the speakers back, and the little board that has the external volume and audio on off buttons to see if I would hear music. There was no sound. I’m really perplexed, particularly since it had been booting up until this point when the power connector was working (before I took it apart).

I’m pretty aware of precautions necessary to avoid static damage, so I don’t think it’s likely that that is what occurred. I’m also confused by the symptoms with the CDs that I described, because I don’t know the relationship between that kind of CD playing (from the front panel, with the computer off) and the rest of the computer. Any suggestions or advice would be very much appreciated. hello there i have a compaq x1000 laptop and im having problem with it and i need an answer for this and hope you can help me.i was on my laptop and it shutted down in intermitted mode and when i plugged in the a/c adapter since it was low on battery and when i try turning it back on it boots up fans spinning and then a sec or 2 later it shuts down and it contiue doing this when i take the battery out and plug in the a/c adapter it wont turn on at all but when i plug the battery back in with the a/c adapter in it it boots up and then shuts itself off?

Its weird that it wont turn on without the battery it is 4 years old and i like to know what could be the problem? Herb Krakau, Tried to boot with only the motherboard, the screen, the processor heat sink, the fan, and the power adapter. At this point, the memory modules were the only other thing plugged in. Result: Fan starts up for 5 seconds or so, and turns off. Try starting the laptop without the LCD screen connected, use an external monitor instead.

Check if the video cable is properly connected to the motherboard. If the video connector on the motherboard has pins inside, make sure there are no bent pins. Check if the memory module is seated properly, move it into another slot and test the laptop again. If for some reason you removed the CPU during disassembly, make sure it’s seated properly and LOCKED inside the socket. qassem, After I pushed on the power button, fans started spinning and were active for a few seconds, LED is on, but my laptop still blank (not display any thing) and not working, no beep sound. It can be a memory related problem. If you reseated the memory module and it didn’t help, try replacing it with a known good RAM.

If you have two memory modules installed, remove them one by one and test the laptop with each module separately. It is possible that one of the modules is bad. Just in case try this. Unplug the power cord, remove the battery and wait for 2-3 minutes.

Then plug the power cord and turn on the laptop. Sometimes it helps. Hello, My Presario R3000 over the past week has been unable to connect through USB to my digital camera or External Hard Drive (from any USB port), won’t read a 1 Gig SD card through the card reader (it shows up in my ‘My Computer’ directory, but tells me to ‘insert a disk into drive F’ when I double-click on it), and refused to read a blank DVD (for backing-up my files). At the same time, however, it DOES allow my to use my USB-connected mouse, and will let me play CDs and DVDs. Do you have any idea what’s going on? I’m at a complete loss.

Andrew, I think this could be a software related problem. The laptop “sees” your USB mouse, so most likely there is nothing wrong with USB ports. The laptop can play CDs and DVDs, so most likely there is nothing wrong with the optical drive or the motherboard controller. You can try this. Using System Restore revert the operating system back to the time when it was working properly. If it doesn’t help, go to the next step. Backup all important personal files and reinstall the operating system from scratch.

The problem with the hp’s is not the cable. There is a small aluminum piece in the laptops screen. What happens is over time, the little plastic piece that covers the voltage converter slides over. Then the aluminum piece ends up touching the back side of the plastic piece where the wires go in. All you have to do is take apart the monitor and slide the piece back over and its fixed. I just did it on my nc8000 that was having the same problem for a while. My screen would go out if the screen was moved but you could still see it a very little bit.

Hope this helps. Compaq evo n160, would only turn on once in a blue moon, then would switch off without warning, at random.

Does not turn on at all at present. One light comes on on the laptop (the one saying the charger is plugged into the laptop). Battery charging light does not come on. Tried with memory, without memory, different slots, different memory. Tried battery only, PSU + battery, PSU only, also tried above with hard drive removed. Nothing happens!

Its a new battery (it did manage to charge it a bit once when it was turned on, and stayed on for a hour or so) but also tried the original old battery. Its also a new psu, which is putting out 19v with the right amperage for that model. When it did power up, it worked fine until it turned off instantly after a random amount of time. Courier did let it fall out of the van on delivery, so put in a courier claim, but looking to find out the probably part that needs fixing/replacing. Nothing happens when power button pressed. Tried leaving it unplugged, without battery for hours, no joy. Tried removing the bios battery, and leaving it unplugged for ages, before putting battery back.

Any suggestions? I have an HP Pavilion ze5460us laptop, key “O” doesn´t work and it beeps for 5-10 seconds on startup. I want to take apart the keyboard and check that specific key. After taking out and disconnecting the keyboard, the underside has a clear plastic cover which is bonded to the main board of the keyboard. The small screws which I suspect have to be removed to completely disassemble the keyboard are covered by this clear plastic shield.

My question is, should I expect any complications when I take out the plastic cover and remove the screws to disassmeble the keyboard? I have a HP Pavillion XH555 40 gig AMD 4 processor that just had Windows XP crash but when I went to reinstall the software, the bios now reads, “Internal hard drive – none”. I’ve since purchased a used Toshiba hard drive that I installed but I still got the same results, and I now have a cracked hard drive adapter to boot. The computer has been running great and the motherboard looks fine.

I don’t have anything cracked underneath, from what I’ve seen so far, but I don’t know if this is something I can fix. Did it just crash and is done? I have problem with my laptop Evo N1020v. When I try to turn on the laptop it don’t boot up but power led is on. Screen is black. I noticed that when my processor isn’t in socket and I try to turn on laptop it of course don’t boot up but all the two fans spin out.

When the processor is in socket the two fans don’t spin out. It seems that there is some kind of problem with my processor and this is the reason my laptop don’t boot up. Some time ago my laptop boot up after many times of trying to turn it on. But now even acces many times don’t help. I have problem with my laptop Evo N1020v.

I am writing again. When I try to turn the laptop on, it doesn’t boot up but power led is on. Screen is black. I noticed that when my processor isn’t in socket and I try to turn on laptop, it of course doesn’t boot up but all the two fans spin out. When the processor is in the socket the two fans don’t spin out. Maybe it’s useful information? Some time ago my laptop boot up after many times of trying to turn it on.

But now even acces many times don’t help. Great website with good resources. After reading some of the appropriate materials, I think I’ve narrowed down my laptop’s problem: I own an HP/Compaq nx9600.

The machine has a very checkered past (already had to fix the power supply, heating system, broken “on” switch, etc), but it’s very nice when it works. Right now, I’m having a problem where when I try to turn the screen on, the screen remains blank, and the computer beeps twice quickly before resetting. I believed this had to do with system RAM – after resetting the RAM firmly, I can usually get it to start up and get to the desktophowever, after a minute or so, the screen goes blank, and I have to restart the machine (after which, the aforementioned beeping loop plays). Could there be something else wrong with the machine? Thanks so much. Joe, You are right, this could be memory related issue. I just looked at the laptop maintenance and service guide and it looks like you can access both memory slot from the bottom of the laptop, simply removing the memory door.

How many modules you have installed? If you have only one module, try moving it into the empty slot. Test the laptop and find out if the problem is gone. Try replacing it with another working memory module.

If you have two memory modules installed, test the laptop with each module separately. Test each module in each slot. Find out witch one is causing the problem.

If the laptop works fine with both modules installed into the slot A, but freezes with both modules installed into the slot B, apparently you have a problem with the slot itself. If the laptop works fine with one module in both slots but freezes with the other module in both slots, apparently the second memory module is bad and has to be replaced. My preceding comment was hasty. Not all models have Maintenance and Service Guides offered (the two I was looking for didn’t). But you can try another model which may offer it.

Then after downloading it, compare the diagrams for similiarities with your model for disassembly. Close enough to do the job.

I searched under my model # and turned up one bogus hit, but a general search (no model #) turned up quite a few to choose from. My model was a Pavillion ze1115. Yeah, I know, most of you already figured this out. Thanks again.

Joseph Santos, I doubt that you can do this kind of repair at home unless you have proper equipment and a lot of soldering experience. Edwards Pirani Penning 1005 Manual Meat here. How do you fix connector problem between video card and laptop motherboard in compaq presario x1000 model. It works only when pressing on the video card area. Apparently one of the connectors (on motherboard or video card) has a cracked solder joint and has to be resolered. I’ve never done it myself because my soldering experience is limited to power jack replacement. i have a presario v1700.

And its been having problems with the video. Whenever i turn it on all i see is different colors or black with white lines. It seems as though the computer works fine its just that the lcd is having problems showing the display. Im wondering if it had to do with dynamic link library being deleted. Me and my brother were trying to free up memory on it since it only has 2gb on it and this took up most of the space and he deleted it than slowly the display started going out until you couldnt even get past the startup screen. Ive been trying to see if it works with external monitor but i havent figured out exactly how that works.

Havent had too much experience with laptops before. But i dont need help with that. Ill figure it out sometime.

corey, whenever i turn it on all i see is different colors or black with white lines. It seems as though the computer works fine its just that the lcd is having problems showing the display. Can you see Compaq logo when you turn on the laptop? If your laptop has a screen like that right from the startup and you cannot see normal Compaq logo, your problem is not related to Windows, something else is going on. In order to narrow down the problem you’ll have to test external video.

If both internal and external video have the same video problem, it could be bad video card. If this problem appears only on the internal screen but external video works fine, it could be bad LCD screen or video cable. If your laptop starts fine and you can see the Compaq logo, but video fails after Windows starts loading, it could be software issue.

Try booting the laptop in Safe mode. Scott Best, My problem is when power is pushed the fan turns but then it quits, sometimes it comes on to password screen then runs about 30 secs and the screen goes to black leaving the power lights on like it is still on Could be memory problem. The slightest touch on the right side of the keyboard it does the same thing Try moving the memory module from one slot to another.

It’s possible one of the memory slots is bad. When you touch the laptop, the memory module loses connection with the slot. Just a guess. Hey I need your advice on two totally bizarre issues that I’m having with two totally different laptops.

The Toshiba Satellite M35X-S149 had a bad drive and only 256 mb memory. I upgraded the memory to specs and changed out the drive. I reloaded and the machine turned itself off 3 times during install. I finally got XP Pro back on there, along with offiice but never go to the stage for antivirus–and now it won’t turn on at all. I wondered if mabye a BIOS update/BIOS flash update would help–but now it won’t even come on. The power cord is funny, yet the port in back is very tight–NOT loose.

I hate to pay a lot of money for the pro to solder it and then it turn out to NOT be worth it. Also, I have a Compaq nx9010 Business lappie and it’s totally insane. I added memory and hard drive–it’s not reading all the memory, plus it can’t find the hard drive. And it’s giving messagds I have never seen before. Holler at me when you can please Sir, I’d appreciate your advice. TIA, Sherry _____ •. I have an hp ZT1290, laptop.

This unit worked fine until I replaced the hard drive. After the new HD was installed and configured, all MS updates installed, I shut it down and didn’t use it for a few weeks.

Next time I booted it up, the screen was black, although I could see the screen by shining a light on it. I tryed these things with no luck: 1) updated BIOS 2) updated drivers 3) ran a diagnostic from HP 4) cleaned the cover switch 5) tried to toggle the screen 6) hooked up an external monitor (worked fine) 7) replaced the display inverter, and checked the backlight bulb (OK) So, What the heck is wrong here? Any suggestions? hello, my frnd did vomit on my laptop compaq presario v3060(thanks for stupid heavy drinking).immediate the screen goes off and now screen is not coming up but power is coming up with LED lights.i have opened the laptop and clean everything.even detach and attach the LCD cable but still nothing coming up on screen. My hardware guys said it is issue of Mother Board(System Board) which needs to be replaced and which is around $250. Can anyone help me in this. I dont think so it damage the LCD, my view is issue with any display chip.any suggestion?

Thanks, Saffy •. I had my monitor go black on me last night, and saw on your site that I could get the maintenance and service manual for my Compaq Presario C503WM Notebook PC (C500 Series) at the HP website, which would enable me to check and reset the cable, if that’s what it needed. Unfortunately, they don’t have one for the C500 Series (this is what they told me via chat). It’s a little difficult to try and explore the monitor assembly without some sort of schematic, so I’m a little stuck.

I’m afraid if I wrestle my way through to the actual connectors of the monitor, I might break the hinges — I really neded some kind of assembly diagram. My co-worker’s daughter changed the bios in her Compaq Evo N-400c and promptly forgot it. I was asked me for help.

I have tried almost everything to reset the CMOS. I removed the main and RTC batteries, took out the hard drive and let it set overnight. I plugged it back in without the main battery (per the Compaq repair manual) and it still asks me for a “Power-on Password.” How is this even possible?

Is there some capacitor I have to drain the power from? I have checked the system board and cannot not find any jumpers. It’s not my computer, but it is still frustrating. Any suggestions?

On some laptops you cannot remove the BIOS password by removing the main and RTC batteries, apparently that’s the case with your Compaq laptop. I afraid you’ll have to replace the motherboard and ship it for service to HP. Ronald, why I can not get the internet working on my presario 1500,it says that I am connected.

But thats it. There is no simple answer to this question.

Could be just wrong settings. Are you running Windows XP? Try this: Start>>right click on My Network Places (in the right pane)>>Properties Right click on your network connection (wired or wireless)>>Properties>>Highlight Internet Protocol (TCP/IP) and click on properties button In the General tab you’ll see settings for IP address. This settings have to match your router/modem. In most cases it should be set to Obtain an IP address automatically. hi, there are a few comments regarding broken screens but no answer- hopefully someone can help me here- i have a compaq presario c300. Only half the screen works the lower half is just dead pixels, but if you press the bottom right hand corner of the screen the lower half works (just while pressure is applied).

This makes me think there is a connection problem so i have disassembled the whole laptop (thank you for directing me to instructions!) but dont know what to look for (was hoping to find a trapped wire or something, but everything seems in order!) anyone any ideas? I have been having issues getting my Compaq F730 started. Over the last couple months, I’ve had about 5 times where the computer will not boot. After pressing the power button this happens: – all indicator lights on the front light up – nothing is displayed on the screen, and the HD light never goes on again – fan runs – if DVD is in drive, this spins up – after ~20s the laptop shuts off and restarts. To troubleshoot the problem, I’ve tried this: – take out HD and put in another computer. The other computer read the HD fine.

– boot with a linux or windows boot disk (it started once with the linux boot disk, but I think this was a fluke as subsequent restart problems were not fixed by this). – start with battery only – start with battery out (AC connector was lit up, so I don’t think it is a broken connector problem) – pressing F10, esc, del after powering on.

Nothing shows on the screen – shut the lid and reopen it. (If I remember correctly, sometimes the light on the front went off after doing this, but this may have been when I was testing without the battery in). – hit the computer – reseated the RAM chips I’ve gotten out of the restart mode before but it seems to be random. tom kb, only half the screen works the lower half is just dead pixels, but if you press the bottom right hand corner of the screen the lower half works (just while pressure is applied).

Your description sounds like a problem with the LCD screen, not the cable or wire. You’ll have to replace the screen. quote david: I have a Compaq Presario V5000. The screen is black when turned on. (I know the screen itself is good.) My computer works fine when hooked up to an external monitor. I’ve tried locating a loose connection to the screen by disassembling my laptop. Everything seems to be connecting fine.

Can anyone help? Is there an easy way to toggle between external monitor and the laptop screen?

David, Look at the keyboard. There should be a little screen thingy on one of the F keys (usually f3,f4,f5) Hold down Fn and press that key a few times until you have somthing on both monitors. ValerieH, I have an HP Pavillion dv6835nr entertainment center laptop and the jack is loose.

HP told me it was the adapter and i paid for a new adapter and still have the same issue. HP disregarded my telling them the jack feels loose and talked me into buying the adapter however I am having the same issues. Please tell me how to fix this without having to send HP my laptop because I am to the point of not trusting them anymore after the waste of money on the second adapter.

The power jack is soldered to the motherboard. It’s necessary to disassemble the laptop, remove the motherboard and replace the DC jack with a new one. I explained how to replaced laptop jacks in this post: It’s not easy and requires some soldering skills.

If you don’t know how to solder, I would suggest taking your laptop to a local repair shop. If you send your laptop to HP, they will replace the whole motherboard and charge you tons of money. @ Bryan Terman, I have a hp dv6913rs i shut it down went to start it a week later and it will come up to a hp screen and it has f key does this on the bottom of the screen have tried all of them done the hard reset sum time it will let me in the bois other time Try removing memory modules and test the laptop with each module separately. It’s possible that one of the modules is going bad. Just a guess.

It will get line on the screen hp things its the mother board is there a test for this please Just one line or many vertical lines? If you get multiple vertical lines running though HP logo, this could be motherboard failure. I have a Compaq Presario V3500. Few months ago i can’t turn on my laptop. But went i plug-in the battery charger, there is a light turned on (it is look normal when battery charger is pluged and switch on). But i still can’t turn on my laptop.

When i bring it to computer service centre, they told me the motherboard was spoilt and need to change. But i refused to change. Now for your information, after some months, when i try luck to turn on the laptop, suddenly the laptop turn on. Everything going as normal. The system is okay. But few days later until now, my laptop is doing the same problem. It cannot turn on.

Please help me to solve this. @ Maran, after some months, when i try luck to turn on the laptop, suddenly the laptop turn on. Everything going as normal. The system is okay. But few days later until now, my laptop is doing the same problem.

It cannot turn on. Please help me to solve this. If the laptop starts intermittently like that, it could be one of the following: 1.

Failed memory module. Bad connection between the memory module and motherboard. Failed motherboard. Try reseating both memory modules. Test the laptop with each memory module separately.

I have a compaq presario 2500. I disassembled it and did organised the srews in a proper way I thought! I did download the service manual for this presario, but the pictures are not detailed enough and my memory ( braincells ) is not that young anymore to get it together again. I would like to find a video or photos with more detail so i could see the proper places for parts better then is possible with the pictures from the service manual. I googled for it many times, but can`t find the right video for this model.

This repair might be harmful for your health and baking motherboard in an oven probably is a bad idea. It could be toxic. I did this repair for myself, at my own risk. If you decide to use these instructions, please do it at your own risk. FIXING “NO VIDEO” ISSUE BY BAKING THE MOTHERBOARD. Problem description: I had an abandoned Compaq Presario V6000 computer. It was turning on when but after a few seconds turning off by itself.

There was no video on internal screen or external monitor. I tried another AC adapter, new memory modules but it didn’t help. I was pretty sure the motherboard failed. Research: After I did some research on the Internet, I found that this is a known problem with Pavilion dv2000/dv6000/dv9000 and Presario V3000/V6000 motherboards and most likely related to the graphics chip failure. The graphics chip is soldered to the motherboard.

Apparently, there are bad solder joints between the chip and motherboard. Overtime the chip separates from the motherboard causing all kind of video problems. Possible solution: One guy suggested baking the failed motherboard in a conventional oven preheated to 385 degrees Fahrenheit for exactly 8 minutes. This process should reflow the chip solder joints and give the motherboard a second life. I had nothing to lose and decided to give it a try.

Here’s how I did it step by step. First of all, you’ll have to disassemble the laptop and remove the motherboard. Remove all peripheral components installed on the motherboard (memory, cooling module, CPU, etc). Remove all protective mylar tape. The motherboard will be baking at a very high temperature and all that can burn has to be removed.

Take pictures while stripping down the motherboard. They will help you to put all removed protective films back in proper locations. This side of the board has been stripped down. You can see the graphics chip on the right side from the CPU socket.

Remove all mylar from the other side of the motherboard. Disconnect the audio cable. The motherboard will be seating in the oven on the baking pan. In order to elevate the motherboard above the baking pan I’ll use a few screws. I installed screws in four corners of the motherboard. There are plenty holes for screws.

You can see there is a 3/4 inch gap between the board and desk surface. The graphics chip is facing up. Place the motherboard on the baking pan. Make sure it’s not touching anything. Preheat the conventional gas oven to 385 degrees Fahrenheit and place the board in the middle of the oven for 8 minutes. You’ll smell some burning plastic in about 6 minutes.

After that remove the baking pan with motherboard and let it cool down for about 30-40 minutes. Assemble the laptop back together and see if it works. This fix worked for me! After I assembled everything back together, it started properly right away. The video had no glitches. The next time I explain how to repair the same issue.

This method requires no disassembly. For more permanent fix check out.

ALR, But you must be very careful with the temperature and time, condensators might not like this temperature. That’s why I said try it only if you have nothing to lose. Also this is temporary fix. The problem will come back in some time. I installed a new hard drive and loading Windows 7 for test.

I don’t know yet how much this repair can last. Ideally, on this laptops you need to change video-chip completely, or at least reflow the BGA. That’s right but how many people can do it at home? I agree with Adam.

I bought a hot air gun from Argos in the UK for £12.99, stripped my Sony Vaio, put a G-Clamp (TWO FINGER TIGHT ONLY) on it and heated evenly about 3mm from the top of the chip untill stuff started to smoke! As the board cools very gently tightened the G-Clamp a bit at a time untill it was to the point where I would have to use a minimum force to tighten any further. Basically what you need to avoid is putting too much force on the chip while hot as all of the solder underneath will just spurt out like an over-filled jam sandwich! I advise practicing on another simular type chip from a broken TV or something first. It worked after re-assembly but as Adam said it only lasts between weeks and months, just like the X-Box 360 X-Clamp repair which is much the same thing.

Basically it is down to the new weee regs that don’t allow the use of leaded solder anymore. The lead played a vital role in solder giving it much better tolerance to expansion through heat where as the new stuff just cracks.

I don’t see why decent graphics companies like Nvidia and ATI don’t make all of their GPU’s the same as CPU’s with pins that slot into a socket. In fact those boys who write the weee regs should insist on it because the professional repair of this more often than not is not worth the charge, especially as it is likely to fail again. I do the repair for other people now but only offer a 28 day guarantee. When I tell them why, even with my modest fee of £75 most of them prefer to just go buy a new laptop with 12 months warrenty. Imagine globally how many laptops must get scrapped and the increase in electronic waste? And this problem doesn’t seem to be getting better, in fact from my experience it’s getting worse.

effthech, i have a toshiba A205 laptop but whenever there is the charger plugged into the laptop the screen image gabbled but if operate it with the battery alone the system works fine. So please i wnat somebaody to help me out.

Not sure what’s going on. Did you test the output voltage on the AC adapter.

Maybe the voltage is not correct? What if you remove the battery and start the laptop only with AC adapter? Do you still have a garbled screen this way? What if you start the laptop in Safe Mode? The image is still garbled? My HP Pavillion dv9700 laptop’s screen shows a neon green rather than black for all pixels.

If I start to close the screen, when it gets maybe three incles from being all the way shut, I can see the black go back to black, but when I reopen the screen the problem reemerges. I did open up the LCD area and attempted to wiggle/squeeze various wires but not seemed to do anything. Further, the brightness on the LCD is dimmer than I would expect (but still easily seen)and the function keys for brightness do nothing to alter the brightness of the screen. From some various forums, I think it may have something to do with a slightly loose connection to the motherboard, but that’s a guess.

Can you help? Bill, My HP Pavillion dv9700 laptop’s screen shows a neon green rather than black for all pixels. If I start to close the screen, when it gets maybe three incles from being all the way shut, I can see the black go back to black, but when I reopen the screen the problem reemerges. I did open up the LCD area and attempted to wiggle/squeeze various wires but not seemed to do anything.

Further, the brightness on the LCD is dimmer than I would expect (but still easily seen)and the function keys for brightness do nothing to alter the brightness of the screen. I think there could be a problem with the LCD cable. Just in case test your laptop with an external monitor.

The black color on the external monitor should be displayed properly. My neighbour came round the other day with his V6000 asking if I could take a look. It had a very similar problem, when switched on their was no display (even with an external monitor) and it seemed to be resetting itself every minute. After trying all the usual stuff without success and then reading on various web sites about this being a fairly common fault I asked my neighbour if he’d like me to give this a try and he said yes. I followed the disassemble guide then cooked it at 200 degrees Celsius for 8 minutes. Cool down, rebuilt and hey presto, it’s working again! Did the bios update which seems to have the fan running all the time now but my neighbour is happy and he’s promised to make a donation.

Unfortunately he’s tighter than gnat’s chuff so I wouldn’t expect too much but thanks for the great work! Hello this worked on my HP Pavillion dv6000 also. I got this computer from customer whom said that it is broken.

There was a problem that when computer got warm, I mean after 15 seconds, the video failed. After baking motherboard the video is working for now. I’ll report later if the motherboard fails in couple days. My failure on baking was that i put screws on wrong positions.

My opinion is to use more screws because my motherboard bended a little. Also I backed it on normal oven so temperature is not so accurate. As a result of that SD card reader on bottom side of motherboard popped off but it is easy to but it back again. I’m not sure if it popped off before removing motherboard from oven. Maybe motherboard should cool longer time in oven but I decided to remove it because motherboard was bending. Temperature which I used was a 200 celsius, cooled 20 minutes outside (I checked temperature of motherboard before putting it back on pc). I recommend this as last option.

BTW: On the video driver chip, I found a nice packing of dust/lint against the side facing the fan when I removed the fan/heat-sink assembly. The packing was 3/16 thick on the fan side and wrapped around the lower side.

It was quite dense. The fan shroud on my V6305 has a slot in it that faces towards the chip/heat-sink. Dust had been blowing through this slot and collecting on the chip. I sure this contributed to the overheating. The video chip is between the processor and the fan along the brass heat-sink strap. I’m sure the heat from the uP is affecting the video chip too.

(Poor HP design? Not sure how I would cool it though. sorry for my english, but im italian, but im here up to all because I’ve got to death with HP! Please first to starting the mod, read all here, because after there is 3 problem by that mod 1-by noise from cpu fan, and if for you is frustrating 2-the life of cpu fan heatsink can is short, depending if go faulty by poor building materials 3-when is not connected with ac power, the battery half hour and is out some considerations their is not one good house for build the pcs, i know something on it, i have a lot of skill for repair, and in the major, the brands who go broken, is hp, hewlett packard, acer, for dont talk of minor brandsall shit DELL? PERHAPS is a little more good, but how all pcs, have 2 problems: the hot and the dust. I all the days dismantle, test, reassemble pc and so on (when you think to buy one laptop on ebay, half dismounted, considering the expensive exit of money from your tasks for take the spares which them dont have; monitor? 70 100$ hd caddy?

40 50$ who exit from your task, but how much during? Yes ok, there is a lot of affairs on ebay, but if you are in USA dont buy in China or Europe overseas, find to buy near you, ok?

For a lots of reasons (if the spares object is broken, wrong etc)for send back the spares, the cost is lower than overseas, undstnd? But dont buy that brands and, up to all, buy like new if its possible for you. NOW, for all peeps who dont know, when open you laptop for do that reflowing (i talk of dvxxxx series), cut the white wire of the cpu fan. This causes the CPU fan does not stop, NEVER.

YES I KNOW WHO THIS IS FRUSTRATING BECAUSE OF NOISE, BUT YOU WANT SEE YOUR LAPPY MITIGATING IN THE CENTURYS? THEN DO THAT. But dont leave the cutting wire as is, put insulating tape on the cutin wire (if the wire go to touching the internal circuit, your laptop can go burnin, then attention on it or.puff! On the cutting wire, im not sure however, its is at your own risk if u want do a try for put on circuitmahare you stupid?) this can help your motherboard to live but much more long as you can imagine. In that manner, the cpu fan never stop, only when reboot your pc laptop stop for 3 4 sec; follow my advice, then after 2 3 hrs, put your hand on the left of the keyboard, where is cpu (at the left of keyboard), how is now? Ok thats all, i have do already 2 times, the reflowing at my dv6000 amd and, chit&chat that fat bstard who now soldering without the lead and, whit that issues have stolen a lot of money around all the worldthe HPyes yes, this make sense, hp pay tax by this stolen money and, a lot of pcs is stopped, the governor is satisfyed andthe earth can breathe, everything fits, this have one sense?

I called that also markets strategy, them are in their luxurious palace and you crybuhuim without pc nowdamn hpbuhuhuuu or in that manner orin what other i can make me satisfied? Now your beard is long till at your knee, and you all are still thinking that, and after there is also the hp assistancenow comings the very cocks amigo •. I bought a persario v6000 off Craigslist about a month ago. After two weeks the wifi stopped working, then about a week later I went to turn on my laptop and it would just keep trying to reboot every 20sec or so and nothing would come on the screen. I read this posting and thought, what do I have to loose? I’m not a computer guy by any means, never taken one apart.

Last night I was up until 3am taking the thing apart and puting it back together. I put the mobo in the oven for 8mins at 385 degrees. I’m now posting this comment with my Persario. I can’t believe this worked.

Hopefully it will last, don’t want to go through that process again LOL!! Thanks so much for the info. I fix computers. Yes, I know there’s a lot of dead HP / Compaq laptop going around, and this “fix” might be a cheap way for people to get a few more months out of their laptops. However, it doesn’t fix underlying problem. Whether you have an Intel ATI or nVidia model makes little difference, the type of motherboard HP uses in their laptops is always going to dissipate a LOT of heat.

It’s thinner than most boards, and heats more quickly. Overheating doesn’t just make solder brittle. Overheating damages the CPU, GPU and memory controller chips all at once. If something is revived, there always a chance some other part will fail next @author Please edit this article to include a WARNING about toxic fumes. There’s a lot of debate, but the lead in solder can burn off, especially above 400° and lead fumes are a known cancer-causing agent in the state of California.

The plastic fumes might be just as bad, I don’t know, but at the very least, clean your oven afterward. Ok, everyone? This sounds like the same cause of the Playstation 3’s “Yellow Light of Death” (YLOD) error and has basically the same exact solution. I’ve fixed my PS3 myself by doing the same thing except instead of putting the motherboard in the oven I used a heat gun and only heated the GPU instead of the whole motherboard. Worked like a charm and I imagine you would get the same results with the laptop as well.

In addition, when reflowing connectors on a motherboard it is also wise to use “no clean” Flux to make sure the connectors do not crack again in the future. The same problems to HP DV2000/6000/9000, Compaq Presario V3000/6000. It’s all about poor motherboard/graphic chips and terrible case designs to produce heating problem. I still am thinking “baking mobo” is not safe. Becuase in the mobo, are there not only graphic chips but also many capacitors and resistors etc which are very weak at heating.

PC/Laptop repair technicians use certain machines for reflowing/reballing mobos and chips. But alternatively they use also heat guns so that they can heat up only targeting graphic chips or specific parts of mobos. Thanks to my heat gun, I could fix some laptops. But anyway, what you did deserves my thumb up. I have a HP Pavilion dv6000 laptop that has been “dead” for around 5 months now. I’d looked around the internet and figured the Nvidia chip was most likely the problem but I hadn’t been brave enough to try the reflow fix.

All the reflow videos I’d watched made it seem very complicated. So when I found this page tonight (and the step-by-step disassembly instructions also on this site) I figured I really had nothing to lose. I was very skeptical, I mean cooking a motherboard does not sound good! But after several hours of taking apart, baking, and putting back together I am now typing this on my “dead” laptop. It’s been resurrected!! Thanks for the awesome instructions!!

WRAP IT IN A TOWEL!!! You won’t need to disassemble the whole laptop lets face it, most of us aren’t teck savvy Hello.

I just want to share my experience with all of you. I read somewhere that wrapping an xbox in towels fixes the rrod (red ring of death) a video card failure just as explained here. Well, my HP dv6000 had the same problem. No video and would not boot, just kept flashing the led’s on top of the keyboard with black screen. I took out the hard drive and batttery, turned it on and wrapped it with towels so air would not enter the vents. I left it like that for an hour or so. Then I went back and pressed the power button until it turned completely off.

The laptop was very hot. I didnt move it at all until it was cool again thinking that if there was molten solder inside, I might damage a connecton moving it. Well to my amazement, the computer booted up and WORKED without any problems. Conclusion: Wrapping your computer in a towel will generate enough heat to reflow and fix the solder joints of a video card.

Just remember to remove the battery and hard drive to avoid any heat damage to it. Walliot, I took out the hard drive and batttery, turned it on and wrapped it with towels so air would not enter the vents. I left it like that for an hour or so. Then I went back and pressed the power button until it turned completely off. The laptop was very hot.

I didnt move it at all until it was cool again thinking that if there was molten solder inside, I might damage a connecton moving it. Program Bimbingan Dan Konseling Sma more. Well to my amazement, the computer booted up and WORKED without any problems. Thank you for comment. I think I might try this trick.

I have an HP Pavilion tx1000 tablet with supposedly bad NVIDIA graphics laying around. I’ll try your fix on my laptop. Walliot, I cannot believe it but looks like it worked!!!!! I didn’t have paper towels at work so I wrapped the laptop (HP Pavilion tx1000 tablet PC) with bubble wrap. Just in case removed the hard drive and battery. After the laptop was sealed, I turned it on and let it run for about 1.5 hours.

Almost forgot about it. Before I went home, I turned it off. Touched the bottom and it didn’t feel that hot. Next morning I unwrapped the laptop AND. It started booting!!!!

I’ll make some photos tonight and upload it on the website. I guess, I’ll try this trick with another failed laptop. I have a hp dv2000 (but exactly it’s dv2808ca), and I had the same problem, namely it didn’t work at all.

Simply no response, computer was totally dead. So, I fully disassembled the laptop, looked on the motherboard solders with magnifying glass and found two of them disintegrated. Funny, the two solders connect that small thing that is on the other side of the motherboard, right by the nvidia card. So, it isn’t hard to guess which part was to blame for overheating this part of the motherboard.

Anyway, I applied new solder (plumbing one:)), and it works!!! Reconnecting elements and cables were easy, but i don’t remember exact places for cables, so i can’t close outside covers. But it’s only a matter of time. Anyway, thanks for the advice!!

For those who have the same chipset, the two solders are numbered C178, and are on the top side of the motherboard (so you don’t need to disassemble everything like me and have a problem putting it back) •. I’ve been battling the same problem on my DV-6000 for a few days. The laptop would turn on for a few seconds then off again. Somtimes it would stay on for about 15 seconds, then turn off again. For a while I had it booting up and running normal except the wireless card wasn’t being detected at all. I tried everything recommended even replacing the card with another, yet it didn’t help.

Finally I pulled the motherboard out entirely and baked it in the oven for 6 minutes at 385F. Reinstalled exactly as it was before and voila! It boots and runs fine and now detects the wireless card.

I recommend this for those who have tried everything and have had no luck. I’ve seen good results for baking video cards and motherboards in the past as it applies just enough heat to reseat the solder joints that break over time. Hope it helps and good luck to those who continue to run into this problem.

Easy way: Remove HDD/battery, connect laptop to AC power source, wrap laptop in bubble wrap or a towel (I used a towel), let it run for an hour. Turn it off, let it cool for a while (until it feels barely warm/room temp or even cool), turn on and be happy. This worked for my HP Pavilion dv9000 with an Intel Core 2 Duo T7200 processor and a nVidia GeForce Go 7600 GPU. It had strange font problems, I rebooted, and was greeted with a grey screen with weird patterns/other stuff. This method, which I recently used, fixed my laptop. Thank you Walliot.

PROBLEMS: turn on lappy.powers up but black screen/lines on screen/turns on then turns off again. MY SOLUTION:ps. Viseo of this repair on Youtube (no it’s not mine). TOOLS- philips screw driver, very small butane gas torch, tiny socket tool for 2 bolts beside wireless cardand as much knowledge as you can get on the stripdown and reassembly process_”Google” if you have to.

Disconnect batteries,remove CPU and RAM! Strip lappy down to motherboardlocate GPU chip (usually NVIDIA chip)chop a square piece into centre of thick cardboard slightly bigger than “GPU chip”, place over GPU chip and secure to board with cellotapeget thick aluminium foil, or thick aluminium builders tape (100% aluminium) and put over cardboard and as close to the “GPU chip” as possible (wrap tightly around the “GPU chip”. If your happy that you’ve done that right, fire up the “Very Small Butane Torch” to a pencil like flameand go in. – keep torch about 8-10cm from “GPU chip” start counting as soon as butane torch tip touches the “GPU chip” count to 20 fairly fast (this is melting the solder on the GPU chip back into place)slowly circle the “GPU chip” until the count reaches about 20 (1,2,3,4.20)imediately remove the Butane torch and turn off flame (put torch in safe place away from everything, to cool down)give “GPU chip” about 5 minutes to cool down. —–Reassemble the lappy.(there should be no spare screws) —–Reattach bios battery to M/board (on Compaq presario v6000 bios battery located beside wireless card and Ram/Memmory chips) If it doesn’t Power-on properly the first time, Strip it back down and try againcounting from 1-30 fairly quickly. If the jobs done right.this should fix the problem straight away.

This also works on other lappy’s with same problems (apparently) I have only used this on Compaq presario v6000 (X2.this lappy I’m using right now is one of them, RIPLEY’s believe it or not!) 1x Hp Dv2000, and an Xbox360 gaming console with RROD.!!!!Xbox may need redoing in a couple of months or yearswe all know how reliable they are (but I do love themHALO!!!!) If you find this usefull! If you follow instructions to the letter.”WRAP THE THICK ALUMINIUM FOIL” as close to the “GPU chip” as possible, and you won’t burn any other part of your M/board.remember about 8-10cm away from “GPU chip” when you are using the Butane Torch •. PS.most laptop problems start when your cpu fan and cooling vents get blocked up with dust and soot before or after any repair you need to have the cpu fan unit pulled apart and cleaned thoroughly or the problem will come back and bite you in the ass again!

Also!even though they are called Laptopsthey shouldn’t be used on your lap unless they are on a flat hard surface, as the cooling system on laptops require good airflow to keep the cpu cooland the cooling vents on most laptops are under neath the laptop.if you are having problems with laptop heating up too much, it might be a good idea (not a cool/I’m hip looking idea to glue 2x small rubber blocks at each corner of the back of your laptop to help with better airflow (cooling). OR!just but a laptop cooling pad, with it’s own fans fittedthese also come in clear plastic with really cool/hip neon coloured lights. Regards Allen Davis •. Hello you dont need to put you laptop into owen just remove your processor and on your laptop if its power on correctley then only hetup your gpu unit with hotair gun for 1minute and after the cool down assumble it and enjoy if you se same problem again then do it again and little peace of almonium foil on the gpu unit before reasumbling you heat sink because we hav put some presseure on your gpu by the reason of heat its lose their their paste which hold gpu unit on motherboard.

And sorry 4 poor engglish. The oven trick worked, however after using it for a day the computer would start acting up after about an hour or two being on. The screen starts flickering, mouse won’t work which forces me to shut it off. When the laptop cools down after a few minutes, I’ll power it back on and everything works fine again but then eventually will start acting up again. Is there a connection loose?

Did I not reassemble the laptop correctly? Is it possible to be the same problem acting up? Should I put it back into the over for a longer time or use a heat gun? Any help would be appreciated. i was seriously doubtful about this article, and for most part i was thinking this wont work.

Then again, as the guy mentioned he had nothing to loose so i had also made up my mind that i’ll have to dump my laptop and get a new one. Mine is XPS M1530. I have got it working again by the same method and this re-heating the motherboard thing really works. The logic is corrent, the heat melts the soldering and it flows back into the places. BUT Its just a temporary solution, the performance goes down. And you cant use it again for heavy games or anything which uses heavr graphics Goodluck with your experiment •. The thing is, Nvidia 8600M GT, chips were made of poor heat resistant materials.

So melting the soldering, only clears the way of the video signal, but actual processing is done in the chip which is made of poor quality materials.(which has been made offical by dell and Nvidia). Its like Overhauling a car’s engine. It will make your car run again, but you cant race with it. So, when you try playing heavy games again after repair, you’ll notice Lag and loss of FPS as time goes. This solution Though defintely works.

This is not only dangerous, but can and most likely will reduce 90% of laptops to a complete mess. The purpose of reflowing a system is to heat the GPU and ONLY the GPU up. Using the “Let’s bake this in the oven.” technique (if it can even be called a technique it’s plain butchery) is completely ridiculous. To reflow a board it’s quite simple. This can be used on ANY motherboard. – Open up the case and get down to the motherboard – Strip away any plastic protectors on the board.

– If you have it, use some ELECTRICIANS FLUX (** DO NOT USE PLUMBERS FLUX YOU’LL FRY THE CHIP COMPLETELY!!!**) and drop the flux with a dropper or needle underneath the GPU chip while holding the motherboard at a 45 degree angle to help the flux run underneath the GPU chip. This helps the solder rebond to it’s pins easily. Make sure you run the flux through all the GPU and don’t worry about excess flux, once you heat the board up it’ll evaporate.

– Coat the WHOLE BOARD except the Graphics Processing Unit. (or CPU if you’re reflowing the CPU) in aluminium foil (tin foil) – Using a HeatGun (bought from any hardware store for about £15-20 – I use a 2000W TITAN on low power which heats up to about 280-300 celsius) simply keep the heatgun at about 3-4 inches above the chip and move the heatgun in a tight circular motion over the chip for about 60 seconds. – Once this is done DO NOT move the board for the next 20 minutes!!!!! (If you do, you risk completely screwing up the GPU and it’ll never be fixed!) – Reassemble after 20 MINUTES! – Plug in and give it a try. Reflowing without using a reballing reflow work station is never guaranteed but using a heatgun is the ONLY way to be attempting to reflow any component without a proper reballing reflow workstation. Hope this helps and please, for your own safety DO NOT put your darn motherboard in an OVEN!

Not only do you risk blowing a capacitor with excessive heat but umpteen other things can go wrong not to mention inhalation of toxic fumes from a component that might have exploded or been damaged! Regards The IT Guy •. The heat gun method worked for repairing the dead display, but didn’t fix the no-battery-charge or dead wi-fi.

After a couple of more heat gun applications on the south bridge and wireless card area, the display went out and the machine would not boot again. I then tried the oven method and that fixed it all!!

Removing the metal heat sink mounting brackets prevents the plastic insulators under them from melting and smelling up the oven. Thanks for the write-up and pictures. If I hadn’t seen it work, I wouldn’t have believed it. Anyone doing this fix should be sure to update their BIOS to the latest version because it fixes the fan control issue that causes the overheating in the first place. HP has the BIOS updates available for download on their support site.

The detailed service manual for disassembly/assembly is available also. Fantastic Website!!!

Was able to diagnose my Compaq Presario F700GPU issue and reflow the solder. I used the aluminum foil covered cardboard with a hole to heat up the GPU from the back side method. Used a 125W floodlight about 1″ above the motherboard for an hour, then flipped the motherboard over with the GPU on top, used the same foil covered cardboard exposing only the top of the GPU and used my heat gun for 1 minute until it started to smell like something was happening. Let it cool for 1/2 hour, put it all back together and it has been working for 3 days so far.

Without this fix, the laptop was headed for scrap. Thanks for the support!

I used a different variation of the bubble wrap idea. Remove the hard drive and the battery. Open the screen out, and just wrap the keyboard section with two or three layers of foam wrap. Seal off the vent holes on the bottom first with kraft tape.

Find a box,like a large fed ex box, that will accept the warpped keyboard. Hook up the power supply and turn on the unit. Make sure you get it to at least stay lit. You may need to hit F7and F8 several times if it is cycling on and off but not booting.

When you’re sure the unit will stay on, put the keyboard in the box but leave the screen up and out side. Now take towels and plug up the gaps around the screen and lay a few over the box. Leave it alone for two hours. When you check it after that time period, you should hear it running normally. Hit the mouse pad and see if you have a screen.

It worked for me and cost about 1 cent in electricity! It’s been running fine for a week, and my wireless came back on line as well. You do not need to bake this or take it apart. Open the screen up, turn it on, hit f7 an f8 togethere if it won’t keep the blue lights on until it does, hook up the power cable and wrap the keyboard in plastic, AFTER you tape up the vent holes on the bottom.

A plastic bag is fine. Now warp the keyboard in a good, dense towl and leave it on for about an hour. Listen every so often for the fan to be running. When you hear it constantly on, unwrap and use as usual. My WIFI was out on my unit as well as the boot up, but after this fix, it worked too! Still working after a whole month of daily use. If it goes again, repeat the process.

I’ve done that already once before. I can confirm that the concept here is sound. In essense you’re melting the solder that connects the graphics chip to the motherboard and resoldering it – ghetto style! If you’re not the most technically minded soul, there’s an easier way to do this semi outlined above. Remove the battery and the hdd (to avoid damaging them) then wrap the whole damn laptop in towels – the goal being to stop airflow in the case. Plug it in and turn it on.

Since the graphix chip runs hot, it will accomplish the same effect of melting and re-soldering itself to the motherboard. I left mine running in this mummified state for about an hour and then turned it off and let everything cool down for about 12 hours (way overkill for the cooldown, but as I was at work, it didn’t really matter) anyway, after not working for about a year and a half, voila, when I powered everything back up – video! Not sure how long it will continue to run, before the crappily designed board will repeat the same problem, but we’ll see! I had a problem with my HP Touchsmart TX2 (and my TX before it). I tried the copper spacer trick and the heatlamp over the (NVIDIA) Northbridge chip of my TX several times but this didn’t work.

Sold it on ebay for parts and bought a TX2 (yes I didn’t learn from the mistake that myself and thousands of other people have made). Then I saw this post after the same thing happened with my TX2 a month after the warranty ended AAAARGH! Blinking caps lock and number lock lights, Blinking HP! I stripped the motherboard of foam and the lithium battery only, then put the motherboard on three balls of aluminium foil (one of which was supporting the heatsink over the ATI Northbridge chip) on a flat tray and stuck it in the convection oven for 8 minutes preheated to 200 degrees Celcius. I then let the motherboard and oven cool with the door partially open for ten minutes then took the tray out to cool for another 15 minutes (the smell was not good, and the fan wires had melted).

Otherwise the board looked fine. I put the board in the computer and fired it up and WOW, crap in a bag and punch it it worked!!! Well, ok, it worked for 6 months of hard use then the black screen of death reappeared. I’ve just repeated the process again which takes about an hour and a half each time. I also take the opportunity to clean the dust the fan and heatsink. If you’re considering selling a knackered HP laptop (that has the black screen of death) for parts I would have a go at the above.

Remember to let the board cool slowly to avoid stressing the parts and soldered joints. What have you got to lose apart from an hour and a half of your time and a kitchen smelling of melted plastic?:o) •. @ Nestor, i have this coputer presario v 6000, but my problem is with the power on all the unit. When i plug the charger on the laptop the blue light arround the plug is on but only in there when you press the on boton no light apear there or any sound like the fan or anything just the light on the charger area. First, I would try reseating both memory modules. It’s possible one of the modules has a bad contact with the memory slot.

If it doesn’t help, try removing memory modules one by one. Test the laptop with each memory module separately. It’s possible the laptop doesn’t start because one of the modules is bad. My Presario have the problem of blank screen and so do my sis son and couple friends too.HP sucks any way how can I test the AC adapter before the frying operation? The special thing about my hp is that it worked perfectly when I was working in Saudi Arabia and never get heated!!!!

Later it started doing the rebooting thing, I put it aside and get a Toshiba with 3 years warranty:), then one day I remembered the hp junk and took the HDD format and plug-it to the system luckily it worked so I installed UBUNTU linux OSfor 2 months it worked soo fine till one day re-die.I’ll do some work on it and hope it will return to life, but the question is how to know that the AC adapter is fine? man, i really don’t have any words to thank you! And seriously if I have a credit card, i would send you because you really deserve it!!!!

First of all, i have Hasse Laptop ( Chinese product ) with Nvidia it was perfect but suddenly the monitor stopped working so i connected it to external monitor and it works fine! After while, some green vertical lines started to appear ( ofcourse in external monitor ) and the color wasn’t perfect! And now, it became dead!

I took it to many repair shops and all of them couldn’t fix it ( or in another word, they fix it but the problem returned after 2-5 days ) so i bought new laptop. And i don’t know why i suddenly remembered my old laptop and google it to find your post. And i tried Oven trick because im poor and i don’t have the heating GUN! IT WORKS and really really thank you so much deep in my heart! And as i usually say ( nothing have, nothing lose ) and here im the winner 😀 have a nice day sir and i will remember this adventure for ever! I know this is a long dead tired thread but just wanted to post something that might help someone else. The reflow methods listed are good and will (if only temporarily) allow you to use your laptop again..

They used zero thermal paste on the gpu and there is no contact with the heat pipe inside. I suggest using thermal paste as well as 2 copper shims (one on the CPU and one on the gpu) to help disperse future heat. The first time I did the “oven” method and it gave me about 60 days of use.

Then it did it again. Sadly the oven method destroys heat sensitive components and although the screen worked again, it wouldn’t recognize the IDE drive for very long then it would “lose” or drop the drive. The oven method can cause every component on your main board to float from where it should be. I wouldnt use the over method. It ultimately does more harm than good. I currently use the a torch with liquid flux and an aluminum heat shield to float the gpu back into position. Reballing is near impossible for the average person without templates and the proper equipment but with a pen-torch/heat-gun, liquid flux, thermal paste, as well as copper shims for both the CPU and GPU it is possible to give your broken laptop a new lease on life.

It doesn’t work for all Laptops with blank screens, the 6 beeps of death, or gpu floating issues, but it has worked for me and I have been using this once dead laptop for 2 years post reflow with no secondary problems or another blank screen. Also take care when reattaching the heat pipe not to over tighten it or you could push your GPU off its pads. I will post a video detailing the process but it is basically a combination of 2 or 3 solutions rolled into 1 long term solution.
