Hi fellow gurus',
I need your opinions.
I have a server (IBM x3400 - 7973-52M) that now requires me to keep the on/off button pressed and held pressed to stay on. If I just press and release (as it is meant), it attempts to start and just turns off again. To then start it again, you have to remove the power cable completely until all residual power is drained from the PSU, then press and hold.
I have replaced the on/off switch assembly with a new one - same problem.
I have replaced the PSU (non-Hot Plug) with a refurbished unit - same problem.
I have flashed to latest BIOS - same problem
I am thinking; Is it the refurbished PSU that is questionable or is it the system board that is faulty?
Am I missing something?
