I have an HP 4525S.   It will not boot.  It has Windows 7 pro installed.
When I press the ON button, I can hear the normal disk drive sound but then no video displays.
I have attached an external monitor, no video on that either.

I have read all the manuals I can find for this unit.  There is no troubleshooting information.

How would you troubleshoot this problem?

Thank you for your help.
