    Hey,

    My Power Mac G5 power button is gonne. It works sometimes, sometimes it doesn't. Is there anyway o turn the machine on without pressing the power button?

    Thanks!

    Original G3/G4 keyboard perhaps? This one came with a powerswitch on the keyboard.

    I am pretty sure that when Apple stopped making those keyboards and replaced them with the Apple Pro Keyboards without the power button they stopped putting the extra circuitry in the USB ports to support keyboard startup in macs released after that. Seeing as that was in 2000 I'm pretty sure the G5 powermacs will not be able to startup from those keyboards.

    The only thing I can think of short of fixing it is setting it to start up every day at a certain time, and reboot after power failure etc in system prefs to ensure that its always on when you want it.

    You can just short the pins out on the logic board with something like a screwdriver. You need to short the right ones though.

    I just crimped some thin wire to the correct pins on my G4, then connected a small micro switch to the other end for ease of use.

    Not sure if it the same issue, but my G5 PowerMac has no problem starting from my Apple ADC monitor switch which is a USB function.
