I have a Gateway m6885u laptop computer. I got a Blue Screen and then the screen went black. The computer seems to boot ok, the fan works, DVD and Hard drive lights work, and the battery charges normally.
I have tried using an external monitor and still nothing.
it's so easy to replace, at least for the one receiving the money ! :-(
In most shops they even advise to buy a new laptop unless it's under warranty.
But usually it works until 1 day past that !
try to repair it ! Check out my link !
it's cheaper and as efficient !
I understand and agree that replacing the CPU is not always cost effective. What you're suggesting ─ a reflow ─ though, SOMETIMES works fine for problems with solder joints. This does not appear to be an issue with a surface mounted chip, however. The integrated GPU built into the CPU appears to be at fault here (just a prognosis), and if you heat the CPU far beyond its TJunction, you may exacerbate the problem or even destroy the chip.
I suspect the display adapter went bad. From what I see, that laptop uses Intel UMA graphics, which means the processor handles output to your monitor. If my suspicion is correct, you will need to replace the processor.
