My e-machine model number t2984 will not turn on when the power button is pressed. We just bought a new power supply and nothing changed. the machine simply has no response to the power button. no beeps, no fan movement, nothing. I reset the bios jumper, and the cmos. Please help!

Re: Will not turn on.
Did you try bypassing the switch?
To do so:
Remove the case
Follow the wire from the power switch to the motherboard
Remove the wire from the 2 pins
Use a screw driver and touch both pins at the same time, creating a connection
That would be the equivalent of switching the computer on, if it powers on then you know the switch is bad and just need to replace it. If it does not turn on I would be 99% sure it is the motherboard as you already swapped the power supply.

Ok, test the power button pins. First disconnect any power source to the computer. Then, find the power pins on your motherboard (the one that your case's power button connects to. Usually two wires, one red and the other black). Grab a jumper a connect it to those two pins, they usually have the letters "pwr" or "power" printed next to them. Then, once you've done this, with the jumper connected, connect the power cord to your power supply. It should turn on by it self. If it does, then the problem is the power button. If it does not do it, then the problem is the motherboard. Good luck.
