Default The Computer Power Button


I am interested in a remote/wireless solution for turning on a computer from a distance. Im running MCE 2005 and I know the remote can turn off the computer, but not on. So what exactly does the power button on a computer do? Does it bridge the circuit and send a signal to the mobo to turn on the computer? Cause i was thinking maybe a small drawbridge typed motor that would move a bar down, complete the circuit and then flip back up...

If anyone can point me to links about how i can accomplish this, itd be great. thanks!

The power button does just exactly as you said. It has two wires connected to the motherboard. When you push it, it briefly connects the circuit between those two wires and turns the computer on. You could do the same with a screwdriver by just touching the two wires together.

CPU: Intel i7 2600k @ 4.4 GHz
Cooler: Cooler Master V8
Mobo: ASRock Z68 Extreme3 Gen3
RAM: Corsair Vengeance 16 GB DDR3 1600 MHz
GPU: EVGA 560 Ti
HDD: Cruicial M4 SSD 128 GB
HDD 2: WD VelociRaptor 300 GB
PSU: Corsair TX650w
Case: Corsair 600T Graphite Series

there are better ways to do this. all you need as a remote transmitter and receiver, one like a wireless doorbell can do the trick. if you can find a wireless door bell that can play a single "ding" as the door ring. with a few modifications you can use the speaker as a signal wired parallel to the power switch and the single ding will simulate the button being pressed. i'll see if i can dig up a tutorial i saw a while ago. while written for an xbox the principles are similar.
