Why won't it power up?
My G4 won't power up. I press the power button it turns on the off immediately. The fan tries to start but stops immediately. After I press the power button once, it won't light up again. I have to unplug the CPU and then plug it back in. Then when I try it again, same thing. I already replaced the little battery inside. Didn't help. This has been going on for a while. If I keep trying, sometimes it starts. I have the 867Mhz machine. What part is bad? Can I replace the faulty part myself? If so, is there step-by-step directions for this anywhere?
Is this a good question?
