If it turns on with the jumper set then I think it wouldn't be a power supply issue. The power supplies are fairly dumb and just wait for an indication to turn on from the motherboard. I think this is a common issue with O2s but I'm not sure of the cause; you might also check whether the RTC is working? You could also check the standby voltage on the power supply, I guess, if you really wanted to rule anything out there.Seems both me and Jenna have connected a 'jump-start' switch connected to 'PWR ON' near the NVRAM, in order to get our systems started.
