I'm trying to trouble shoot a Compaq Presario 4560.

Symptoms are when the power switch on the rear of the machine is switched on
the Green Power LED lights up immediately and the Green HDD activity light
stays 'solid' green for about 15 seconds and that's all that happens.

There is no video what so ever, I tried a known good monitor.

I put a boot disk in the floppy drive and there is no apparent attempt by
the system to try and read from the disk.

I have no idea how to get into the BIOS setup, especially with no video at
all.

I have put the "Rescue" CD in the CD-ROM drive and there is no apparent
attempt for the system to access it.

I have removed the HDD and CD-ROM drive and tried to boot from the floppy
with no success.

The next thing I'll try is to put a video card in one of the PCI slots and
see if I get any video from that.

Any other suggestions before this thing hits the scrap heap, which is
probably where is belongs!

Thanks.....
