This mirrored silver door G4 (dual 1.25Hz) cannot be put to sleep -- at least not for very long. Choosing Sleep in the Apple Menu will get a power down for perhaps 15 seconds and then the system initiates a wake up. After a recent power supply replacement, there is no variable speed on the fan, either -- it's full bore all the time.

I have experimented with the Energy Saving Panel, without success in resolving the issue. Could the wrong power supply have been installed?

Got any PCI cards installed such as USB2 which will cause these problems. As for PS check with whoever did the install. Could well be as there are quite a few models.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
