Re: laptop. no video
What laptop does he have, and how old is it?
If he hasn't already, the first step would be to try resetting the BIOS.
The second step to try would be to remove all RAM modules and install a new or borrowed one and see if the system is able to boot.
If the problem still persists, then it's possible that the BIOS is corrupt, or other hardware is faulty (such as the motherboard or CPU) which would be difficult to diagnose and repair.
