I own a Dell Latitude D630. I purchased on 2007. It’s been problem free for 4 years. Since last year, the boot screen was double with lines through it or not booting at all. something like this:
It worked for a while with connecting to external monitor, then totally stuffed.
After some researches, this problem is fairly well documented as a fault with the nvidia quadro nvs m135 video card. The internal solder becomes brittle with age and causes this exact type of failure. Unfortunately, even though this chip is considered a separate component with it’s own memory, it is installed permanently on the motherboard itself. I don’t think it is worth to replace the motherboard for a such old laptop, then I decided to put it aside.
Recently, while I was researching other thing on youTube, I came across the most curious suggestion for a fix by baking the motherboard for 10 mins at 390 F degree. Initially, I didn’t quite believe it. However, it makes scene that the heat will soften the brittle solder which allows the chip to gently re-seat itself.
Then I decided to give it a shot with nothing to lose. I put the laptop a part and took the motherboard out by following this video clip :

After that I followed this one to bake the motherboard:

Once all done, I reassembled the laptop and it is working beautifully. If you have same problem, it is worth to try.
One more last thing, don’t forget to update the BIOS to latest version:
