DL380 G5 Not Booting, Odd Hard Drive Flash pattern

[kknuckles]

I have a HP DL380 G5 that has been working beautifully since 2009. Today, the unit locked up completely. No display, no keyboard or mouse availability. We turned it off and then back on. There are no indications of error, however the hard drives begin to flash from 8 to 1. After a while they stop flashing in reverse sequence. They then start all flashing at the same time with the exception of one. It will be about a second behind the others. They will continue to blink every few seconds with the one trailing it. It will then change to which one is blinking behind the others.

I have been unable to access the bios, and I can't get it to show me any post messages.

Any help would be greatly appreciated.

Have you tried unplugging the harddisks, and seen if you could access the BIOS?

You might alway want to put a voltmeter on the BIOS battery, too.  You may want to also start unplugging devices from the motherboard.  If it has two power supplies, perhaps pull one out, check, and alternate if necessary.
