Not for a server, but many years ago my brother had his work desktop fail after he let it cold boot for the first time in a very long time.

Normally he would leave his work machine turned on but locked when leaving the office.

Office was having electrical work done and asked that all employees unplug their machines over the weekend just in case of a surge or something.

On the Monday my brother plugged in machine and it wouldn’t turn on. Initially the IT guy remarked that my brother didn’t follow the instructions to unplug it.

He later retracted the comment after it was determined the power supply capacitors had gone bad a while back, but the issue with them was not apparent until they had a chance to cool down.
