I have a laptop that will not fully power on. And would like to know what may be the problem. I have spent a while trying to find out why. I have tried everything I found online from the discharge method / changing out the ram removing battery / anything plugged in to usb ports and nothing works.
I have came to the conclusion that the video processor has failed. But would like a second opinion.
The problem started when I was watching a video on youtube when the screen went black. But was still getting sound from the video.
When I try to turn the laptop on the following happens.
Key board lights flash like normal
Battery charge light
Able to get power via usb ports.
Does not power on!
HDD "Can be connected to another pc and can retrieve files"
internal cooling fans.
monitor back light.
Sony VAIO Model PCG-71511L
