How to fix HP video problem

posted in: Motherboard | 182

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. :)

  1. Had this problem on my G62 model.
    The graphic chip was failing few times a day. Then I uninstalled graphic card driver and everithing was ok. I backed up all my data and then I throw that stupid hp away and since that day, I’m hp hater!
    No more hp products for me, that’s for sure.
