well as I told before workstation is auto power on with or without jumper set, CPU Modul reseated. Could it be simply the Power supply itself that causes this issue, or simply not delivering correct power to the Board ?

when I first got my working o2 it autopowered everytime I plugged it in. once I was able to get a null serial cable for usb I figured out it was working (has to be regular to null or you have to get an adapter) so after it fully booted and I got video output with a special adapter I was able to power it down properly. never auto started again UNLLLLLLLLLLLEEESSS you pull the power cord when its on it will autostart when plugged in until you shut it down properly again. also what is up with that red o2 in your picture did you paint that? I have 2 that were smashed up in shipping and after some HEAVY gluing sanding and epoxy casting I painted one green and one white. But that red one seems to have factory text mask
