Laptop wont load bios or OS
Interesting issue here.
When I press the power button, the HD activity led light comes on for just a second, I feel the HD spinning up and running, the fan kicks in and runs, then nothing. No leds flahing, just power led, no beeps, no screen and no bios.
I'v discharged static build up (battery out, power button held down 30") and tried both mains & battery to no effect. There were no precursors to this issue.
So I can deduce the laptop is unable to complete POST in pre bios, despite the lack of beeps yet can supply power to fan & HD.
Now the GPU is GForce 8400m GS, aware of the issues with the 8xxx series, I'v kept the air flow clean and use a laptop cooler. Possible suspect though it never ran hot and all worked fine till I turned on a couple of days ago. Now I understood that a failure of the 8xxx series usually presented a degraded screen, lines etc rather than failing post.
I'm backed up and use my second laptop so nothing urgent, just a oportunity to learn.
I am interested in hearing from hardware geeks and their thoughts.
