I have a PPC G4 AGP graphics model, 450 mhz single processor with 2GB ram running OS9.2.2 on a 120 GB Western Digital HD & OSX 10.4.11 on a 30GB Maxtor HD. When I shut the computer down (doesn't matter whether it is running in OS9.2 or OSX) the fan in the power supply keeps running as does the larger inside case fan, and a little red light near where the ram chips are mounted stays lit, similarly to how it is lit when the machine is running. It appears to shut down normally, and there is no signal output on the screen, however the fans are still running.....? For now I have been unplugging the machine when it is not in use to prevent the fans from running constantly however I am wondering why this is happening and if it is ok to just continue to unplug it when not using it? As soon as I plug the power cable back into the computer, the fans start running but it does not boot up until I push the start button and it then boots up normally into either OS/HD. If I don't push the start button, it would just sit there with the fans running. Is this a signal of an upcoming problem with the PSU? Any easy fix other than replacing the PSU?
So far I have tried: resetting the CUDA switch and the PRAM to no avail. This machine runs a SCSI desktop drum scanner in our photo studio and is not used too often. It is one of two machines we have just in case one fails however due to living in Brasil at this time, and the fact that these older parts are not easy to come by down here, I am hopeful to solve this issue ahead of a more disastrous result . Also, because it is not used frequently, it is not an option for me to keep the machine running at all times. Any help is greatly appreciated!
