Hacking a power button on a PC

I'd remove the button altogether and use the holes and the solder pads to put the capacitor in it's place.
Just remember to meter the pads to see which is the positve lead and which is negative.

Which is good if he was just going to use a switch, he wants to use a cap. If he doesn't get the polarity correct, best case scenario nothing happens at all, worst the cap goes *pop* and he has to get another cap.

This is probably a stupid question but I just want to make sure, If I leave the button in place and the wiring I just ran to the button outside the cabinet will the capacitor interfere with any of it. Reason for this is because I want to be able to also power down windows by simply pressing the button outside the cab?
SirPeale:
I dunno.

I would think so.

I've done this on a couple of Dells and it turns out to be pretty simple. On the small PCB remove the ribbon cable (the one you've labelled as "This ribbon goes to the power button" on your photo) and you should find a standard set of pins for the power, HDD lights, etc (none of them are labelled). The number of pins here has been different on both the Dells I've worked on so it's a case of plug in a power header and try it, if it doesn't work move onto the next set of pins.
Of course you'll no longer be able to turn on the PC via the PC power button, but that's not really a problem.
