But last evening, after pressing the power-on button on the cold computer, there was no video even though no Nvidia driver was installed. The video performance was reduced as expected, but it was acceptable, so I thought the problem was solved.
SONY VAIO PCG 5L2L MOTHERBOARD THERMAL PASTE SOFTWARE
I uninstalled the Nvidia driver software (using Add/Remove Programs) and the computer ran for a few weeks.

I tried re-installing Nvidia driver from Dell site and the generic driver from Nvidia’s site, but although each worked for a while, the problem returned. This instance of “stupidity” allowed me to recover use of my computer so I could back it to USB drive before trying other solutions to the problem.) (So much for the popular “definition” of stupidity, which derides trying the same thing over and over while expecting a different outcome. It can take dozens of iterations and several minutes of patience before you are rewarded by seeing your dead screen resurrected. If nothing appears on the screen within three seconds of power on, repeat this procedure from step 1. Wait three seconds for something (such as the manufacturer’s logo) to show on the screen.ģ. Using the power button, shut the failed machine down, then immediately power on.Ģ. In each of many instances of such failures over the past 3 months, I’ve been able to get the computer to boot normally by persisting in the following three steps:ġ. The most-often observed failure symptom is a black screen (no video) during and after booting. At other times, the Blue Screen Of Death (showing the generic hardware failure code) might occur. My Dell D830 w/Nvidia Quatro 135 sometimes starts flickering the video, won’t respond to keyboard or pointing device, so I have to shut it down using the power switch. If you’re patient, you might be able to back up your “no-video” computer before tearing into it. Will it last for a long time? I don’t know. If that’s the case with your laptop, make sure the thermal pad positioned correctly.Īfter I assembled the laptop back together, the video started properly! Some laptops use thermal pads instead of grease.

This video was made for Xbox 360 motherboard but should apply to any laptop motherboard too.įinally, I positioned the heat gun above the NVIDIA chip about 1 inch away and turned the heat gun into the position 1.Īfter 50 seconds I turned it off and let the motherboard cool down for about 20 minutes.ĭon’t forget to apply new thermal grease on the graphics chip when you install the heat sink.
SONY VAIO PCG 5L2L MOTHERBOARD THERMAL PASTE HOW TO
I found this video explaining how to apply liquid flux under the chip. I’ll definitely do it next time when I have to fix another motherboard. UPDATE: Some people mentioned that I should have applied some liquid flux underneath the chip for better results. Just make sure there are no large chunks of the grease on the chip. It’s not necessary to make it perfectly clean. You can remove thermal grease using alcohol swabs. If there is thermal grease on the chip it has to be removed. After that I cut off a square opening right in the middle, same size as the NVIDIA chip. I cut off a piece of aluminum foil and folded it a few times to make my protection shield thicker. To protect the motherboard from the heat I used a regular cooking aluminum foil. After 50 seconds the solder melted completely. I positioned the heat gun about 1 inch away from the penny and turned it on.Īfter about 40-45 second the solder started melting. 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.

I’ll be using an Ecoheat heat gun EC-100.

In most laptops the graphics chip located under the CPU heatsink (and it has NVIDIA logo on it), so there shouldn’t be a problem locating the chip. In my example I’m using a motherboard removed from HP Pavilion tx2000. If you don’t feel comfortable doing this repair, take your laptop to the repair shop.įirst of all, you’ll have to disassemble the laptop and remove the motherboard. Proceed at your own risk and don’t blame me if after this repair you’ll get a very expensive door stop. While doing this repair you may damage the motherboard and make it unrepairable. There is no guaranty this method works all the time. I think this method is more reliable and the repair should last for a while. But today I’m going to fix it using a heat gun.īasically, I’m going to heat up the graphics chip with a heat gun to solder it back to the motherboard (reflow). When the laptop runs hot for a long time, the graphics chip separates from the motherboard and video fails.īefore I tried baking the motherboard in an oven or use bubble-wrap. The graphics chip soldered to the motherboard. Laptop turns on but there is no video on the screen or external monitor. Laptop turns on with garbled video on the internal screen and external monitor.Ģ. By the way, I just fixed my son’s Xbox 360 with red ring of death (error 74) using exactly same technique.ġ.
