I have a G4 desktop Dual 1.41GHz machine that has worked perfectly until today. After powering down, I tried to restart by pushing the power button on the computer and nothing happens. After unplugging the computer, letting it sit for about 30 seconds, and then replugging, it will restart normally. But then, I have the same problem.

I read another posting that recommended replacing the 1/2 AA battery on the motherboard and also pressing the CUDA button. I did both of those but still the same problem. I also changed the date/time to the correct numbers.

Does anybody have any ideas?

The battery is the easiest first choice. The power supply is another suspect, but that one's expensive.

Try unplugging the mouse and keyboard, then try the power button again. A shorting USB cord can cause issues.

Do you have any other 3rd party devices connected? Or PCI cards?

Make sure the battery holder is holding the battery securely, and that the contacts (battery and holder) atre clean and shiny. A crappy battery connection can be as bad as a bad batttery.

Exhaust all your easy possibilities before worrying about a major hardware failure. Try the USB connections thing reader50 mentioned right away - a USB cable can go bad without your knowing it if the device is idle, but when the computer restarts it provides power to everything and will find a short and refuse to start.
