Hacking a power button on a PC
<< < (7/8) > >>
mrracer:
Well I got back into the front panel took the PC apart and took pictures of the front power button panel. Unfortunately I can't really try anything until I or someone helps me on determining the positive and negative leads on this board. I've attached some pictures of the back and front of the panel.  hopefully you guys can figure it out by just looking at it!? Please let me know what other info you need.  ???

The mobo number was engraved on the mobo (was not on a sticker) Did I grab the wrong one?  ???
SirPeale:
We're talking about the leads on the motherboard itself, not the PCB with the switch.  You could just remove the switch and solder a cap in it's place.  You can't tell by looking at it which is positive and which is negative, you'll need a multimeter to determine that.  Put a lead on each leg of the switch.  If the number is positive, then whatever the black lead is on is the negative one.  And if it's negative, it's obviously the opposite one.

And yes, the computer must be plugged in to get this reading.  If you feel uncomfortable with this...well, I can't help you there.

that shouldn;t be to hard to figure out which pin on the ribbon cable is power and ground.  Get a continuity tester (like one on a multimeter), take off the cable form the little circuit board and start testing the header with the switch to find out which pins are the power.  Then, if you use a razor and cut the ribbon cable you can splice into those wires.

Thanks SirPoonga, I went ahead and just took out the front panel based on the circuitry in the back and the position of the powerbutton I was able to determine the positioning of the power and common lead, I went ahead and checked it with a continuity tester just to make sure of the positive and the negative and soldered two cables to the back of the panel and ran them to the push button on my cab. It's working great. Now that I have that working...
I'm enthralled by the idea of using a "capacitor" to short out the push button, I'm just still not quite sure (based on the instructions) on how to properly do this.
Since I figured out the power and common on the front panel can I soldered the capacitor to the push button itself and get the same result? Can anyone please confirm this??

It dosent really matter which is pos or neg, they both go to a button and then switched, as long as you havent changed anything else.
