Answers :

Okay but you need to be very careful. Open ther server up and short the power switch wires. Trace the power wire to the motherboard, take it out, and short the two pins on the motherboard with a piece of metal and as soon as it's on remove the metal. A more permanent way is to replace the power switch obviously.

My emachines T3828 will not power up. I changed the power supply, but that didn't help. my next suspect was the power switch. I found that the wires wer a little loose. Thinking that the power switch wires were one unit, I pulled them.
