Today I show how to fix a known video problem on some HP laptops using bubble wrap.

Most likely the fix is not permanent but this will buy you some time, enough to backup personal files or even use the laptop until you get a new one. There is no guaranty this fix work 100%.

Here are some HP models affected by this known video failure problem: HP Pavilion dv2000, dv6000, dv9000, tx1000 tablet PC, Compaq 700, v3000, v6000 and probably some others.

If you know more models, please mention them in comments after this post.

CAUSE OF THE PROBLEM:

As I know, the video problem somehow related to NVIDIA graphics chip located on the motherboard. Overtime the graphics chip separates from the motherboard and the video fails.

SYMPTOMS OF THE PROBLEM:

The computer turns on and all LEDs light up but there is no video on the screen or external monitor. The internal screen remains completely black and blank.

I found this trick mentioned by Walliot in this post. This trick called “towel fix” and used to fix “no video” issue in xbox360.

HOW TO FIX:

1. Remove the battery and hard drive.
2. Plug the AC adapter and turn on the laptop. Make sure it’s is actually on, all LEDs should work.
3. Wrap it up with towels so all air intakes are closed.
4. Keeps the laptop wrapped in the towel for about one hours.
5. Unplug the AC adapter from the wall the let it cool down (do not move it for a while).
6. Unwrap the laptop and try tuning it on.

I didn’t really believe that this trick might work and tried it just because of curiosity but… IT WORKED!!!!

#1. HP tx1000 Tablet PC repair.

First, I tried this fix on a failed HP tx1000 Tablet PC.
I didn’t have paper towels at work but I had plenty of bubble wrap.
I closed it in a tablet mode (with hard drive and battery removed), plugged the AC adapter and wrapped the laptop properly in bubble wrap.

After that I just waited for about two hours and unplugged AC adapter from the wall. Waited for about 30 minutes and tried turning it on.
Success!!! It starts with with video.

I just couldn’t stop and tried the fix on another one.

#2. HP Pavilion dv6000.
This is a different model with very similar failure symptoms. It failed exactly the same way as the first one.

This time I did something extra. To make sure there is no cool air coming into the case through the bubble wrap, I closed all air vents with sticky tape.

After that I turned it on from AC adapter (again with hard drive and battery removed) and wrapped the base.

It was running like that for about 60-70 minutes but then I noticed that all LED lights went off.

Not sure what happened. Maybe the motherboard overheated too much and shut down on its own. Anyway, I didn’t touch it for about 30 minutes and let it cool down.

My fix was successful again! The laptop turned on with video and booted to the desktop.

HOW THIS FIX WORKS:

Here’s my understanding of how this fix works.
When you run a laptop wrapped in towels (bubble wrap in my case), it gets very hot because there is no air circulation inside the heatsink.

The heatsink gets so hot that it melt solder between the chip and motherboard and the video chip gets resoldered to the motherboard.

Now I have to test for how long this fix last. :)

    This procedure is called reflowing of BGA soldering.. As being said before, I would not trust this fix to run for long – month if lucky.
    In the ideal world you need to get video chip off the motherboard, clean the solder, reball it and solder it back to the motherboard, but I wouldn’t risk it doing at home without required equipment (costs thousands).

    Great work for discovering this kind of kludge!!! I’ll try this fix next time I have hands on dead pavillion.

    Noob Rescue Says:

    Just like Max said, this is a temporary fix. The problem is due to certain circuits loosing contact with the motherboard. If you are trying to recover files and don’t have an external enclosure, then this should help to back them up before your computer fries again.

    A permanent solution is to replace the motherboard.

    I think you are right, but for someone anxious to get personal data back or just make the laptop work for a while this could be a very easy and valuable solution. To be hones, I wouldn’t put any money in fixing this problem. Ideally you have to replace the motherboard but it’s too expensive.

    If you are trying to recover files and don’t have an external enclosure, then this should help to back them up before your computer fries again.

    This is a very good advice. If you are lucky and your laptop boots after this fix, back up all important files ASAP. After that just have fun with the fixed “zombie” laptop. :)

    Yep, but I really doubt that you can find a brand new motherboard for these laptops. Most motherboards out there are refurbished.

    I am so grateful for this advice……so far i have worked on about 23 HP laptops with similar problem. I have a blower…so i take everything apart and heat the motherboard with the blower. But in few weeks it goes off again. I want to know how to replace the chip.

    int21h,

    So far, so good – customer happy and no problems whatsoever. I was wondering if this method would work on video card as well, as some HP models are well known to have construction flaw that results in fail-chain: WIFI -> Video card -> and motherboard finally.

    It might work. Basically it’s same method as described in my post – overheating the CPU and “resoldering” the faulty NVIDIA chip.

    If you could keep us updated if result is permanent, that would be great.

    So far my “fixed” laptop work fine. :)

    if you worked and did not burn your motherboard is a lucky man. please all the people who have video fails go to a service technician first. the only way to fix definitely the re-soldier or “reballing” process, but also works “reflow” is the same as explained here but with professional tools.

    Tomas Says:

    Thanks man! It worked perfectly! I wrapped the computer with 2 nylon bags, a towel on the top and some blankets on the back and bottom. The screen I left it open so that it wouldn’t get damaged with the heat.

    I left it like 1:30 hour and I started smelling burned plastic. So I turned off the machine, uncovered it and waited for it to cool down. It was very hot!

    Then I put the hard drive back in and now it is working.

    Just in case though, I will leave the program “TeamViewer” very accessible in my desktop in case I have to get in blindly if the fix is just to last one month. It’s a pity to throw the computer away, so if I can use it from another computer, that’s better than nothing.

    But for now this works, and I will enjoy my display once more.

    I will also post a link to here in HP’s forum for all the people who couldn’t get into that class lawsuit against NVIDIA.

    Thanks!

    Tomas.

    Hello All, interesting comments, I don’t normally reply to these things but I figured in this case I would. The correct term for what has occurred is re-balling of the BGA(BALL GRID ARRAY) Chip. I own two repair facilities(1 located in Silicone Valley, CA. & the 2nd in Concord “East Bay” ca.) this is all we do all day long 30-4- laptops a day, for a lot of Laptop repair Companies. We service customers in every state in the country as well as several locations outside the US. I assure you it is cost effective and it definitely is an ideal option to replacing a board. With that said, here is some additional information for you we see all brands not just HP, from MAC, Acer, HP, IBM, Dell, Toshiba, etc… Hope you get the picture it is not just HP, but laptops in general run very hot. When solder becomes molten the chip as it cools sucks in dirt and contaminants from the board. This produces what is called a cold solder joint. If you are lucky and you can do the above process to a laptop with out completely frying the chip(which by the way is not recommended)then you will have re-flowed the solder. But as someone mentioned this is what we call a band-aid fix, we offer a 90 warranty to the parts we repair or replace. We couldn’t possibly do this if it didn’t work, nor could we do as many laptops as we do.

    The proper thing to do as someone stated above is to pull the chip, clean the pads and the board, re-ball the chip and re-apply directly to the board. Not only does it take the proper equipment to do this, but it takes experience. NO ONE who does this with success publishes the times an temps, which are essential to do the work even if you laid down the thousands of dollars for the BGA equipment.

    One final note is that when someone reports “NO Video” this doesn’t mean that it is automatically the video chip. There are 5-10 different components that control whether or not someone sees an actual picture. In some cases it is video chips but certainly not all, also unlike other companies we have the ability under high powered microscopes to jump from one pad or trace to another, when there is a short on the board.

    The bad thing is that after 1-3 re-flows the chip is shot, which means higher expense, if it is sent in right away a re-ball of the current chip is usually all it needs to repair it, as long as your not using the laptop on a blanket, the carpet, your lap, or a comforter, etc…

    Hope this helped everyone…

    Best Regards!!

    HP Pavilion dv9925nr model fe695ua

    I purchased a hp hp pavilion dv9925nr model fe695ua in fall of 2008. In August of 2010 my computer begin looping on and off. then the screen was blank one day I turned it on. I took it to bestbuy where I purchased it and they sent it in to be looked at. Came back with a diagnoises of bad motherboard. it would cost me $400 to fix it or should I say replace the entire motherboard. I tried the blanket trip first for about 15min. I was afraid I’d burn something up. Then I tried turning it on. Did not work. Then I put it in the blanket for about another 10 minutes and then turned it off and then on. It booted up and now I am on it. I am looking for someone who works on the motherboard and does not jump to purchased and entire MB first. All I need is the place where its a bad wire connection or chip nvida that needs help. I am convinced this is whats going on by the sounds of many others who are or have experienced this problem. HP is a rats hiney for not fixing this problem. ugh

    but I am looking for someone who works on the different components on the motherboard. someone who has experience but wont charge me an arm and a leg.

    Please email me.

    thank you

    back again. I was trying to upload the newest version of adobe flash and playing poker at the same time and all of a sudden got this weird loud noise and the screen went white with black little dashes across the screen. I had my pc on continuous after the first blanket boot up. after it went down I let it rest and then went back and did the blanket technique again so here I am using the pc again. If I cant find local help I may need to send my laptop off.
    Thanks

    This is amazing, I thought my lappy was dead..I tried a bunch of things with no luck..then I got really upset and in the middle of the night, decided to search the web more thoroughly regarding this issue. Luckily, i came across this article, didn’t believe in it at first, but had nothing to lose and symptoms were exactly the same, so I gave it a try and now it’s back to life again. Unfortunately, I can’t do the proper procedure (re-soldering) as I have no equipment for that, so I really hope it’ll work for at least 6 months, but people here say a month is the longest one can get.. WEll, I’m a bit more optimistic, at least I know what’s wrong now.. Maybe i’ll just sell it while it works.. Huge thanks anyway, you made my life happier again.

    And yeah, my laptop is Asus X55s which has a quite powerful graphics card – GF 9500M and it’s not soldered to the motherbord, so it’s replacable. The whole thing started with freezing in videogames. I’m thinking it just lacks proper cooling, I’ll try to think of something and hopefully avoid further “black screens”. But I guess the best solution would be – new videocard. We’ll see how it goes..

I could do the “bubble wrappage” again, but with some time on my hands I’m going to disassemble the unit and heat-shim-regrease both the CPU & GPU. Yes,the “bubble wrap” was only temporary, and is great for retrieving data. The permanent solution for me will be to reflow the chip in question. There are other articles on this site to help one if you are tempted to perform this act.

    Often no video in a laptop means a bad inverter board, in most cases a new one is under $20.
    Inverter board powers the back light in the LCD panel.
    You can tell if the back light is out simply by looking at the laptop screen, (powered on), in direct sun light. If you see a clear image of your desktop, your back light is out.

    Eddie Murphy Says:

    So many cheap-ass graphics chips/laptop manufacturers KEEP ON MAKING these design flaws. I cannot believe it. So please, everyone – sue the sh*t out of them until they learn how to do their job! That’s all we’re asking after all. If everything had to be replaced after just 1/5 of the time it should last, then EVERYTHING EVERYWHERE would be more expensive, not less.
    Fight this, don’t be lazy.
    If you’re in the UK, remember, you have to prove the fault was there at the time of sale once six months has elapsed since purchase. This kind of site is GREAT evidence to show to a court that the fault is in the DESIGN (not durable enough due to a cheap BGA manufacturing process). Hence even, for example, 4 whole years after purchase you should be on steady legal ground to insist on a replacement/refund/high-quality repair.
    6 months until an undefined period as the law only says items should last a “reasonable” amount of time. Laptops should last 5 years maybe more, plenty do, so why not yours?

    I for one would be happy to pay, say, £20 more for every laptop in order to have proper soldering on my chips. It’s just less hassle. For now, though, make the dodgy manufacturers feel the pinch – that’s what the law is there for.

    It did work for my dv6000, but only for 2 weeks. I fixed it again but did it the right way this time. Taking the mother board out and reseating the video chip by heating it with a 125wat flood lamp for 3 minutes,(do this from the bottom side and shield the rest of the board with aluminum foil)then press the chip in with a towel for 30 seconds, then regrease the cpu and gpu for reattachment. However, (and this is the big fix) take out the little rubber spacer between the video chip and the coolant line and replace it with a clean penny, greased on both sides. Since repair, it runs perfect.

I’m not sure for how long it’ll last this time but to be honest I’m not as optimistic anymore.

    I don’t think your problem is related to the inverter board failure. When inverter goes bad, the screen loses backlight but you still should see a very faint image on the screen.
    If your laptop screen went completely blank (but external monitor still works fine), it could be one of the following:
    1. Bad connection between the LCD cable and motherboard or LCD screen. Try reconnecting the LCD cable on both ends.
    2. Failed LCD cable. Try replacing the cable.
    3. Failed LCD screen. Try replacing the screen.
    4. There is a chance of bad video cable connector on the motherboard but it’s not a common one.
    It’s hart to troubleshoot these kind or problems without spare parts.

Note: be very careful about using heat on the board for there are several plastic pieces that don’t react kindly to overheating, and explain to your significant other that it’s all to save money!*wink* Cleaned, regreased, and shimmed the CPU & GPU. Re-assembled the laptop,and…”BAM”! It’s acting like a brand new unit!

    waac Says:

    The processor is detachable, so yeah, dont burn that up, its worth quite a bit. However, dont worry, the processor can handle the heat. The degree of heat this operation attains wont melt it. Its the gpu that has malfunctioned and cant take the heat. Thats why works, at least temporarily. By the way, if you are doing any damage to the motherboard, its ok, cause its the motherboard that needs replacing to fix this issue.

    The white screen could indicate bad connection between the video cable and LCD screen. Sometimes reseating the cable can fix the problem.

    Test your laptop with an external monitor. Start the laptop and configure it to output video on the external monitor or even better on both internal and external monitors. What until laptop screen fails and look at the external monitor.
    If external video works fine and the problem appears only on the laptop screen, this could be related to one of the following:
    1. Loose connection between the video cable and motherboard or LCD screen. In this case reconnecting the video cable on both ends might fix the problem.
    2. Could be bad video cable.
    3. Could be bad LCD screen.
    On the other hand, if video fails on BOTH the internal AND external screens, this is graphics card failure. The graphics card integrated into the motherboard. When graphics card fails, the entire motherboard has to be replaced.

    daughter had hp dv4 computer on then she noticed it shut off went dead ,no activity ,went to office depot they said it was a mechanical problem .

    How dead is it? Do you see any light when AC adapter plugged in?
    Maybe it’s just bad adapter and the laptop is dead because there is no power coming to the motherboard?

    I have a Compaq CQ50 that doesn’t get any video the first time I turn it on. After turning it on and off a few times, the screen comes on and works fine. I took it apart and checked the connections, they are all tight. I decided to purchase a new (used) video cable to make sure it wasn’t a bad wire or something.

    Do you think it is the same as the problem you described with the HP Nvidia chip? Any way to re-solder it permanantly? Or, could it be a bad inverter? I wouldn’t think it’s the inverter because it works sometimes.

    Thanks,

    Did you test laptop memory? This could be memory failure.
    Do you have two memory modules installed? Try running laptop with only one module (either one) and see what happens. One of the modules could be bad.

    Or, could it be a bad inverter?

    Do you see a faint image on the screen when the laptop “fails to start”? If not, this is not inverter problem.

    Well… the problem is still there with different memory modules, so we can assume it’s not memory related failure.
    It’s really hard to tell what is causing the problem.
    The following troubleshooting technique require laptop disassembly.
    You can disassemble your laptop to bare bone system: motherboard, CPU and memory and test it in this basic configuration. If it still fails intermittently, most likely this is motherboard related failure. If it works, start adding parts one by one and test the laptop after each part. This way you can find the part which is causing the problem.

    1. Try removing the hard drive. Does your laptop start with video when hard drive removed? If yes, probably the hard drive is bad.
    2. Try removing memory modules one by one. This could be memory failure. One of the modules could be bad. Test your laptop with only one (either one) memory module installed.

    First of all, I would test the AC adapter. It’s possible the AC adapter is dead and the battery doesn’t have enough charge to start the laptop.
    If AC adapter is good, try reseting memory modules. Try removing memory modules one by one.
    If the laptop still fails, most likely this is motherboard problem.

    I don’t know what else could be wrong: it’s either motherboard issue, bad video cable or failed LCD screen.
    You’ve replaced the motherboard already.
    From your description it doesn’t sound like the video cable issue.
    Most likely it’s bad LCD but I cannot tell if it’s worth replacing. It’s up to you.

    I guess you are referencing another post where I fixed failed GPU with a heat gun.
    You have to heat up only the GPU chip.
    The GPU is soldered to the motherboard. The CPU seated in a socket which can be opened. If you know how the GPU looks, it’s hard to confuse with the CPU.

    Most likely this is known GPU failure. HP Pavilion dv6000 laptops are know for this issue.

    how to do this oven trick, or bubble wrap trick since it will auto shut down within 10 seconds.

    Btw, in that case, is it means tat i have to use heat gun? is it possible to use a hair dryer?

    If you going to remove the motherboard, I would go with heat gun trick.
    I believe one guy mentioned that he was able to fix it with a hair dryer, it’s somewhere in the comments. You just have to figure out for how long you have to heat up the GPU chip.

    LaptopRepairBrooklyn Says:

    In our computer repair shop Brooklyn NYC, we have a lot of clients, bringing on for repair laptops with Nvidia chipset failure. Beside HP and Compaq these problem appear to Sony Vayo, DELL and IBM also. The best fix for you, if you’re not a computer technician is to bring it to a computer repair shop near you, and ask them if they’re using the reflow method. The regular air method to fix the falling video chipset will not last specially now in the hot season.
    Also, be aware that a laptop with falling memory chip will have the same symptoms like a laptop with falling video chipset (light on laptop but no video on screen), also before you going to a laptop repair shop try to hard reset your laptop, as they have the tendency to freeze and act like a video chipset problem.

    My daughter’s DV9000 was having similar symptoms (blue lights lit but dark screen, etc.) however it would boot into safe mode okay – it just wouldn’t boot into a hi-res video mode. After fooling around for 20 hrs. with start-up items, etc., I figured it must have been the NVideo driver. I updated that but still wouldn’t ‘boot’ normally. I found this site re the bubble wrap method & said ‘what the heck’ ‘cuz I was out of free options. I took out the battery & disk drives, taped up the vents with foil tape, wrapped up the laptop with a large bath towel & left it on for 75 minutes. Let it cool for 2 hrs. & lo and behold it booted up normally! It’s been good so far for the last 3 days. I told my daughter to look for a new laptop ‘cuz I don’t know how long this one will last.

    It’s hard to tell without testing the laptop without known good LCD screen.
    This could be one of the following:
    1. Bad connection between the video cable and LCD screen.
    2. Bad LCD screen.
    3. Motherboard failure.

    Probably this is not graphics card failure because you still can see the external image.
    First, I would try reconnecting video cable on the back of the LCD screen. This could help.

    Koala Says:

    So to everyone who has owned a HP/Compaq with these problems listen up:

    Short version of my story….Own a DV6000 HP laptop. After being in and out of the repair shop at Fry’s for the better part of 3 years, my extended warranty finally ran out. Once again my laptop died. I felt like this was the end, but started doing research on the problem and possible solutions.

    The problem is with the Nvidia Graphics Chip (GPU). It was not properly soldered to the motherboard; they used a lead free solder which is of poor quality. When the computer would get hot, as most laptops do, the solder would come un-done, causing the connections to get loose, and bam! screen would get black, not boot, beeps, loud fans, crazy lines across the screen, its a little different the exact outcome from laptop to laptop, but you get the point.

    I have tried all the ‘cures’ out there. Blanket trick, oven trick, heat gun trick. I won’t go into detail, but you can google any of the above with HP laptop in the search box and get an answer.

    Conclusion? All of the above methods work, although I have had the best results with the ‘heat gun’ method. It lasts the longest, but requires that you completely take apart the laptop, so it does require some technical skill, although there are many videos on YouTube that will walk you thru the process of taking apart the laptop.

    Bottom Line? No matter what you do, as far as methods go, eventually the laptop will not work again. The best length of time I have gone is 4 months between fixes. The last problem came when I was updating my laptop. As it was installing new drivers, the GPU went out. Because of this the BIOS/registry got messed up. I had to re-install my whole operating system. Unfortunately it corrupted some files when the GPU went out. I had recovery programs, but wasn’t able to get everything off my Hard drive.

    So if you are still using your HP/Compaq laptop and using the trick, please keep in mind that there could be a failure that might cause you to lose files/info. Please keep a backup of all important files (4-8gb USB stick should be fine for most people, they are like $15 now) so you don’t lose anything important.

    I am still doing the trick, but after 3 years I am ready to move on to another laptop. I am tired of the stress and anxiety that I get from constantly working and fixing this one. Recommendation would be this: Don’t buy a HP again. The problem is you usually get alot for the money with HP and that might sway you to once again try them out. Because this could only be a one time thing right? They wouldn’t want this to happen again right? Wrong! I have already seen blogs and reports about additional problems with newer HP’s with i3 and i5 core’s.

    Hope this helps someone out there!

    “Fixing” your laptop this way is a very bad idea. Yes it does reheat the solder on the GPU, but it also overheats EVERY other component on the motherboard. This will not be a permanent fix and will cause more damage than good. The best way to conduct this fix is to completely disassemble the laptop and just heat the GPU to reconnect the solder points.

    It depends on what your goal is. If all you need is to make it working for a while in order to backup personal data quickly, it could be a very good idea.

    The best way to conduct this fix is to completely disassemble the laptop and just heat the GPU to reconnect the solder points.

    Nope, the best way is replacing the motherboard with a new one but it’s very expensive.
    I explained how to reheat just the GPU in the following post.
    http://www.laptoprepair101.com.....hics-chip/
    But it requires complete laptop disassembly and most people cannot do that.
    Also, I believe it’s not a permanent fix either. It might work for a while (and maybe a long time) but also it might fail soon.

    HI Everyone,
    My laptop was died just before a thanks giving and i was very disappointed. It was started but the screen goes Grey (Black and White) look. The sound system was working so I am able to hear the startup sound. The funny thing was i have auto login to gtalk and skype so the moment I logged in people start sending a message and I am able to hear the sound…
    The main problem was, I have not taken the backup of my data yet … and was try to find how to take the backup.
    Here is a trick:
    1. Microsoft Windows has a “NARRATOR” (Speech), so if you hit the windows key + R, it opens the run window.
    2. Type “NARRATOR” and hit enter.
    3. The narrator will start. And it start taking about the open window, the command you type or the button you press.
    4. So after Narrator stared, I attached my external hard disk and run the command prompt by: windows key + R and then type CMD and then enter
    5. It speak everything about the open window, drive name and folder name in the drive.
    6. For example I type dir on c:, it gives a list files/folder name, .. etc.
    7. So I used xcopy command to copy everything from the drive. Goto the destination path and type below command. http://www.computerhope.com/xcopyhlp.htm
    XCOPY /A /E /C/H enter
    Now I was ready to use this method, and I did it… and it works …. Now I install new windows 7 and it works fine. I have to wait and watch how long it work… !!!
    I will post you the updates…

    Thanks

    I just tried this on my HP DV2000 and it worked! I couldn’t believe it but I am so happy! This thing has been dead for years and I am glad I kept it now! I knew it would be fixed one day! Thank you many times!

    Actually its really not a bad idea. in this way. the motherboard will detect over heating to harm the motherboard.(stable heat)
    wont harm the chip set it self.

    but by using a heat blower,spot light heat, or any kind of heating.
    you wont know how long you need to heat it. you just heat it for just 2-3min. then u can see the board have funny puffed-up.

    Thanks for the great idea for presario fix. Previously I had taken in my ailing computer to repair shop. They offerred free diagnostics. They couldnt figure out problem. I have found several solutions on the web and all involve removing motherboard and heating NVIDIA chip. In most cases this works. However, it doesrequire a lot of time and skill without screwing up some connector or component. I needed to get a few hours of reunning time to allow me to transfer to new computer. Basically one has not much to loose, just a cheap, crappy, poorly designed dead computer. Best regards

    I just resurrected a Compaq that has been DEAD for 4 years.
    In the process of trying to steal the touch pad out of it to fix another computer, I came across this fix.
    With nothing to loose, I tried it and IT WORKED!!!!!!

    Hi,

    I ma trying to do the exercise on my HP tx 1200, which has the same identical symptoms. It is not opening now although it is getting th power on. I went to HP Tthey sais they cant repair and i have have to pay 450$ for new mother board. I said thank you & went to another laptop repair shop.They said it is the Nvidia chip problem and they would replace it. And would cost me $150.What should I do? Cant it be soldered and fixed, while i buy in good time a new one.Please suggest.

    If the graphics chip failed, most likely any repair will not last for a long time.
    If you would like to fix it yourself, you can try this heatgun repair trick:

    Wow, thanks lot, it worked and laptop got even to a better state than before. I had some strange lines on the screen for few months and it worked only with generic driver (hanging with nvidia drivers).
    After heating everything is back to original state :)

    For everyone who wants to FIX his broken laptop,
    i’d strongly recommend to use the oven OR heatgun reflow method..
    This bubblewrap is a good theory, but you have to think about the other components, which get EXPOSED to TOO MUCH HEAT..
    This will only shorten your laptop’s life..
    You can better investt 3 – 4 hours in taking apart the laptop,
    and do a oven or heatgun reflow (heatgun beaing the best),
    it will satisfy you way more with a good working laptop..

    Also invest in good thermal paste! (or new thermal pads!)

    Good thing you put the information up cj2600,
    but you should warn other surfers for the damage they could do to their laptops if they use your bubblewrap method..

    How about the over method. Do you think nothing is exposed to too much heat?
    I would say the heat gun method would be preferred if you are able to disassemble the laptop and remove the motherboard.

    On the other hand, if you need just a quick fix in order to access the data, you can try bubblewrap method. It doesn’t require any laptop disassembly.

    THANK YOU! THANK YOU AND THANK YOU!

    IT F*** WORKS! I wrapped it up with plastic cooking wrap (the cheapest) and then with the towel. I wrapped it hard tied. No air at all! I switched on for 1 hour and a half. It got really warm. (do not forget to remove the battery and the HardDisk)
    Then let it chilling out for more than 45 minutes to chill out (with the plastic and the towel on) and it worked. unbelievable!
    The chip is Nvidia GeForce 8400M GS
    Besides my computer is not a compaq o HP but a COMPAL one!
    COMPAL IFT00

    Thank you so much!

    I have about 7 or 8 HP Pavilion boards in the computer room. I tried eBay to get so called refurbished motherboards for DV6000′s. Next I started to look for TX1000 boards. After I got 4 bad DV6000 boards from power sellers, I decided to try the heat gun trick. I took apart a TX1000, used foil that I folded & made a 1″ cut out. First I put the gun on low & warmed up the top side of the board. Next I took the heat gun [Note I timed how long it took to get the solder to start to flow. In my case 9-10 seconds heating up a small piece of solder on a penny.] Now that I knew how to time it, I got my cell phone, started the stop watch & when I got to like 20-30 seconds [I waited for a zero, ya know 20, 30, with the heat gun on "HIGH", at 1" away from the chip I timed it to 10 seconds. Just as I was about to lift the heat gun, I had a oven mitt on my free hand, I pressed as hard as I could for about 3 seconds, let the board cool [which took about 5 minutes.] Then I put it back together. Note: I had a set of feeler gauges from my tool box & I measured the space between the Heatsink & the GPU.I decided to do this because that thermal glob that HP calls a thermal pad, was all balled up from over heating. The gap was the same thickness as a penny so you know what I used for a shim. I even went as far as getting a penny from 1981 because 81 was the last year for solid copper pennies. It took me 35 minutes to assemble the notebook, started it up & it was like new. I even got my missing wifi to show up in device manager & actually work. I used this method on 2 TX1000 series notebooks/tablets. My $118 investment for the 2 ended up being sold for $225 each. Now I’m getting out all my DV6000 motherboards so I can finally sell them. Note, I test them for a few days because if the first heat didn’t work, I’d just do it again. Once you do it a couple of times it’s just like no job at all. It took me more time thinking about doing it than just doing it. What did I have to loose? Broken notebooks? Oh yeah & the temperature? I was getting readings in the 50′s [Celsius] Both ended up in the mid 30′s which is perfect. I di buy a small sheet of copper so I could make my own shims & toss the thermal pads…. Good luck to you guys who decide to try it. Hey, if I can do it, you can too. Take care, Dan

    Gokmev Says:

    Lol, I can not believe that this worked on my Toshiba sattelite A200. Here is what I did:
    I wrapped the laptop excluding the monitor side after turning it on(of course without HDD and battery). I could hear fan accelerationg as it gets hotter. As someone else mentioned in the comments, computer shut down when temperature got very high (to protect system I guess). I waited for it to cool down some time and gave it a try. First try was failure, however it started working after second try. I don’t think it is a permanent fix for me as it didn’t work straight away. If is stops working, I can try other methods.

    Thank you

    Got a Dell 9400 lost all video to it to a shop was told I needed a motherboard. Ordered one new but cheap then found this thread.

    Had already dissasembled and thought what the heck Ill give it a try. Thought about the grapeics card and thought might as well bake that dude too. Put it back on and put some srews in the screw holes to elevate it put it on pan preheated the ole oven to 385 degrees F and stuck her in for 8 minutes. Let her cool for about an hour (was busy with something else) put it back in and it works perfect. Still got a new mobo but it was cheap enough so I will hang on to it.

    But thanks guys for the thread I sure appreciate it cudos to all of you.

    Born Skeptic Says:

    To say that I was skeptical about this “fix” would be an enormous under statement. But, like most everyone else reading this proposed fix to the graphics issue, I decided I didn’t have anything to lose. Much to my surprise, after covering the fan and vents with tape, and wrapping the lower half of the machine in a towel, I allowed it to sit running for an hour. I then unplugged the power and let it sit for 45 minutes. Much to my amazement, after re-installing the hard drives and apply power, the thing booted up like it was fresh off the assembly line. AWESOME FIX!!

    Awesome trick. Just revived my HP TX 2000 laptop with it (Problem was nothing on screen and Caps and Num lock keys blinking forever).
    I removed every easily accessible parts (RAM, Wireless card, battery, optical drive, keyboard) and wrapped the computer in plastic bags and towels.
    It overheat in 1h, shutting itself down. After 15 more minutes, I put it back together and it started as it used to for 3.5 years.
    Thanks for sharing this tip!

    The heat gun method is more reliable but it’s necessary to disassemble the laptop.
    http://www.laptoprepair101.com.....hics-chip/

    I don’t think the laptop is worth taking to the repair shop. Most likely they will quote you a new motherboard and make it not worth fixing.

    It felt silly pampering my laptop with towels and bubble wrap and my wife was starting to worry about my mental health, but I figured; if it fails, the motherboard has to be replaced and if I don’t give it a try… the motherboard had to be replaced (according to Sony and laptop repair shops). So, I gave it a try and guess what? IT WORKED! (two days so far)

    Fix for Sony Vaio VPC FE41M with Geforce 7400 go. Had the same probs as this guy: http://www.youtube.com/watch?v=JDl-ZxA2G_Y , but the GPU is now 100% online again. I taped the vents as well but I think that was overdoing it; the Vaio ran very hot (but didn’t shut down).

    Worked on my HP Pavilion dv6655ec with Geforce 8400M GS. I removed battery, hard drive, taped all air vents and wrapped the notebook in towel (display was not wrapped). Plugged AC power, turned it on and let it overheat itself. Progressively the fan speed increased and after 45 minutes I started to wonder how long should I let it run. Fortunately few minutes later the notebook shut down itself due to overheat (ambient room temperature was very hot 31C, so it took little bit shorter, than in the blog post). I disconnected AC and let it cool down for 6 hours (still wrapped in towel). Then removed the towel, connected AC and hesitantly turned the notebook on. To my surprise I was greeted with HP logo and no disk found message (as my hard drive was still removed) :-) Thank you.
