Hi, I've got an old g4 digital audio that isn't starting up. I would like to get it working so that me mom will have her own computer to use. I don't usually mind sharing mine but after getting an eyetv for my computer I'm afraid of her messing up some recordings without knowing it. The computer is showing no signs of getting power and I figured that the Power supply is busted. I was wondering if anyone new how to start the power supply manually without using the motherboard. I know how to do this with an ATX style power supply but now with the power supply that came with this mac. Usually I would use a bent paper clip and touch the black and green connectors. I figure if the power supply starts then I have a problem with my motherboard. If it doesn't start after using this test, then I need to start searching on ebay for another one. I appreciate any advice you could give me.
