I have an HP m7680n. It turned off by itself, and would not turn on by pushing the button. After searching many sights I tried several things. First I checked the PSU. It puts out 5.1 volts and 11.9v on the red. I finally jumped the green wire to a black on my 20 pin and it wiil start up. Ran checks on everything with PC doc and everything seems to work fine. Problem is if I shut it down it won't start again unless I jump it. Any ideas? or what I might check?

:thumbsup: To bleepingcomputer..

If you are able to turn the computer on with jumping the green wire I would suspect your power switch first. Trace the lead from the power switch back to your motherboard and using a small screwdriver (ballpoint pen works too) jump the two pins and see if the computer turns on. If it does then your switch is worn out, if it doesn't then there is something wrong with the circuit in the motherboard. Could be a power supply issue but you said everything tested out ok.

Had the power-switch button go out on a new computer I just built for a friend after only about 3 weeks running. Had never had one go out before and just got a new case (w/PS) and moved everything over. Found out by jumping the pins like mentioned above.

At least she has a backup PS for use if the new one goes out.
