In most laptops the graphics chip located under the CPU heatsink and it has NVIDIA logo on it, so there shouldnt be a problem locating the chip. Ill be using an Ecoheat heat gun EC 1. Compaq-Presario-CQ50-CQ60-CQ70/removing-laptop-motherboard-10.jpg' alt='Compaq Presario F700 Drivers Linux Ubuntu' title='Compaq Presario F700 Drivers Linux Ubuntu' />In this guide I disassemble a Compaq Presario CQ50 laptop. Also this guide should work for Compaq Presario CQ 60CQ70 and HP G50G60G70 models. Start the disassembly. In order to figure out how to position the heat gun and for how long, I tested it on a penny with a small piece of solder on the top. The heat gun has a switch on the handle. There are two positions for the switch. Position 1 slow. Position 2 fast. I used position 1 slow. I positioned the heat gun about 1 inch away from the penny and turned it on. After about 4. 0 4. After 5. 0 seconds the solder melted completely. To protect the motherboard from the heat I used a regular cooking aluminum foil. I cut off a piece of aluminum foil and folded it a few times to make my protection shield thicker. After that I cut off a square opening right in the middle, same size as the NVIDIA chip. If there is thermal grease on the chip it has to be removed. You can remove thermal grease using alcohol swabs. Its not necessary to make it perfectly clean. Just make sure there are no large chunks of the grease on the chip. UPDATE Some people mentioned that I should have applied some liquid flux underneath the chip for better results. Ill definitely do it next time when I have to fix another motherboard. I found this video explaining how to apply liquid flux under the chip. This video was made for Xbox 3. Finally, I positioned the heat gun above the NVIDIA chip about 1 inch away and turned the heat gun into the position 1. After 5. 0 seconds I turned it off and let the motherboard cool down for about 2. Dont forget to apply new thermal grease on the graphics chip when you install the heat sink. Some laptops use thermal pads instead of grease. If thats the case with your laptop, make sure the thermal pad positioned correctly. After I assembled the laptop back together, the video started properly The NVIDIA graphics chip problem fixedWill it last for a long time I dont know.
