More specifically, I'd like to turn my Wi-Fi Catcher Network Locator button(on the left hinge) into a power button. The original power button(on right hinge) has a snapped wire in such poor condition I couldn't reconnect it. As it is, I am able to turn the computer on using a small metal tool to make a temporary electrical contact. My local computer repair guy would charge quite a lot more than I'd like to fix this, so I'd rather find an alternative that I can do myself.
I've altered button functions before, on XP, but only for the purpose of running programs etc. I'm not sure about turning something into a power button, but that network location button seems like the best candidate.
This one's running on Windows Vista. Let me know if you require any hardware specs(although I can't see how that would pertain to this issue)
