Toshiba Satellite boot failure

[Jeff Evans <jwevans1@xxxxxxxx>]

Trying to do something with a Sat. A65-S126 with boot problems.  Windows 
XP installed on NTFS root partition.  Things got progressively worse, 
from Windows not booting until now, when the BIOS screen does not even 
appear.  There does not seem to be any video activity of any kind on 
powerup (screen is black).  I can't tell if the POST passes or not, but 
there are no beeps I can hear.  The CD/DVD drive still spins up if a new 
disc is inserted, and the fan is going.

Any ideas on things to check/try?  Utilities to use?  Any way to narrow 
down the problem even a little bit?  Trying to avoid the need to send it 
in for service if possible.  Thanks for your help.
