 Here’s how I fixed a  motherboard with “no video” issue. Not sure if this fix will last forever but it works and the laptop is back to life.

Also, this fix might work for the following HP/Compaq laptop motherboards: HP Pavilion dv2000/dv6000/dv9000, Compaq Presario V3000 and probably some other models. If it works for you, please mention the model number in the comments after the post.

Proceed at your own risk only if you have nothing to lose. Otherwise, close this page and take your laptop to the professional repair shop.

Problem description: I had an abandoned Compaq Presario V6000 laptop. The laptop was turning on when I press on the power button but after a few seconds turning off by itself. There was no video on the laptop screen or external monitor. I tried another AC adapter, new memory modules but it didn’t help. I was pretty sure this is motherboard related failure.

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 (aka GPU or video chip) is soldered to the motherboard. Apparently, there are bad solder joints between the graphics chip and motherboard. Overtime the graphics chip separates from the motherboard causing all kind of different 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 graphics 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.

STEP 1.

Remove all peripheral components installed on the motherboard (memory, cooling module, CPU, etc…). Remove all protective films from the motherboard. The motherboard will be baking at a very high temperature and all that can burn has to be removed.

Tip: Make lots of pictures while stripping down the motherboard. They will help you to put all removed protective films back in proper locations.

STEP 2.

Here’s how the same side of the motherboard looks without protective plastic films.

You can see the problematic graphics chip, it’s on the right side from the CPU socket.

STEP 3.

Remove all protective plastic films from the other side of the motherboard. Disconnect the audio cable.

STEP 4.

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.

STEP 5.

I installed screws in four corners of the motherboard. There are plenty holes for screws.

STEP 6.

You can see there is a 3/4 inch gap between the motherboard and desk surface. By the way, I positioned the motherboard so the graphics chip seats on the top.

STEP 7.

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 motherboard 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.

Install the motherboard back into the laptop, assemble the laptop back together and see if it works.

This fix worked for me! After I assembled the laptop, it started properly right away taking me to the BIOS setup menu. I didn’t have the hard drive, so I tested my laptop with a Knoppix live Linux CD. The laptop video works great!
