I have been using a Poweredge 2850 for a while now and it's been fine. It was removed from the rack for about 24 hours (carefully, no knocks or bumps and was stored flat as it would have been in the rack, albeit on the floor).
While it was on the floor I was asked what CPUs were in the machine so rather than plug it in and turn it on I just lifted the heatsync off one of the CPUs to have a look. The CPU was stuck with thermal paste to the heatsync so I gave up and put it back.
About 10 minutes later I was asked again so I just plugged it back in (Both PSUs and ethernet, nothing else) and went to turn it on.
- I get no error messages just an orange "Poweredge 2850" message on
the screen. - The hard disks flash once and then the lights go off.
- The fans all spin up but barely at all, nowhere near what it would be like if it was actually on. Barely audible.
- No visual output to the monitor on either the port at the front or back.
I've since reseated the CPU twice more in case that was it, found a thread on the internet which suggested reseating the RAM, CPU, and HDDs, all of which I've done to no avail.
If any other information will help with a diagnosis then please do ask!
If anyone has any suggestions they'd be received with much appreciation!

If the only thing that changed was you removing the CPU from the socket, then it's a safe bet than you didn't return the CPU or heatsink back to the socket correctly. If the heatsink isn't making good, tight contact, then you'll see this behavior. Make sure it's screwed down or clipped down evenly.
