I've never had a problem like this before, so I'll try to make this short. I have a desktop HP Pavillion 8650C and when I press the power button, the computer does absolutely nothing. I hear the sound of voltage in the power area, and I used different cords that work with my printer and I even tried different outlets. I was away for 9 days on vacation, I left it in a Hibernate state, left it plugged in but the switch off on my UPS. I doubt this would cause a problem as I've done it before... I just recreated my account as I haven't had a problem in that long, so I can only offer the maximum of 50 points... sorry. But if you do have an answer to this, please help. Again, nothing turns on at all.
I have checked the wiring from the power button to the motherboard, but since it is compact, and I am inexperienced with hardware, AND due to the fact that the HP's case is so compact, I don't know what else to do (except bang the case, but that hasn't gotten me anywhere...)
Any answer to this question would help, thanks again.
