I know the 6850 is a very old model, but here goes.
I have a poweredge 6850 that a friend of mine has had for quite a while, but hasn't used for about 9 months. He's recently made more space in his room for his computer stuff and so wants to plug the poweredge back in (It's better than nothing, right?) He's not great with hardware, so he sent it over to me to give it a once-over, make sure everything's working, etc...
I put it together and powered it up, and it immediately powered itself down again, quoting misconfig on the LCD screen. I reseated the vital parts and powered it up once again, this time the error was cleared, the fans were running and I thought everything was ok to plug in monitor etc, then I noticed that none of the lights on the hard drives or on the memory risers were on. I tried the CD drive, and it wouldn't open, which left only one answer, no power.
There's no error message on the LCD screen, and both the green lights on the PSU are solid green, the amber warning light is not lit, and the fans are running fine.
However, neither of the system indicator lights are active, and there doesn't seem to be any power to the motherboard.
I've looked up this problem and it appears that several other people have had the exact same problem after long periods of inactivity. However, after running their unit at minimal config (min ram, 1 processor, no drives, 1 PSU) and reseating everything, it started working again, alas, not for me. I've also tried moving the NVRAM jumper, but to no avail.
Is there another solution? Is there something I need to reseat that I'm forgetting about?
Any help appreciated,
