I have a QS 733, nVidia GeforceMX2, 512MB Ram and am now runing Panther 10.3.1. I started haveing problems with the machine with my 10.2.8 update. When the machine is shutdown the fan and hd's stop but the light on the front of the Mac will not shutoff. To turn the machine back on I have to unplug the machine, wait 10 secs, then plug it in, at which time it gives off one long tone then the startup chim and then boots me to the firmware white screen. After typing mac-boot the machine does a normal start and has no other problems. If I restart it also boots to the firmware screen.
I have tried reseting the PRAM, checking the battery(3.64 volts), reseting the s1 switch, upgrading to Panther, and tried to reset the nvram in the firmware.
Does anybody have any ideas?

I have a dual G4 1.25 MD PowerMac running 10.2.7. I also very often get a crash when shutting down my computer. I will either get an error message telling me to press the startup button for 10 seconds or so to stop my mac and then restart or my screen will go blank but I'll still hear the fans running and see the power button lit and the computer simply will not shut down.

This is a Mac OS X problem. I have no problem when shutting down from OS 9.

Anyone can help here ?

I just read an article about some problems that might occur under Mac OS X. It looks like I get a kernel panic when I shut down. Can I use the halt command via the shell to shut down my Mac ? If I can't find what's causing the problem, I might as well skip it but I need some insight here. I'm only beginning to use the Unix command lines...

I've never tried the halt command. To shut my computer down from a shell I normally type "sudo shutdown -h now". But thanks for that, I'll have to look into halt.

I've never once had a problem shutting down from the command line or the GUI and I've been using OSX since 10.1.2.
