G4 450, MacOS 9.1 won't fully sleep

Message #1 - Posted 2001/10/20 - Martin Frost me at stanford...

I have a 450 MHz G4. When I first got it, running MacOS 9.0.2, it would sleep when idle for 30 minutes or whatever the setting was. The green light would go to pulsing amber when it went to sleep.

Then I changed the settings in the Energy Saver to specify a shorter time for putting the display to sleep. I may have set a specific time to spin down the disk too.

At about that point the machine itself quit being willing to go to sleep automatically, although the display and disk would go to sleep automatically after the specified times. The only way I could get the machine itself to sleep (pulsing amber) was to do it manually.

I tried all kinds of combinations in the Energy Saver panel, but no setting would allow the machine itself to go to sleep by itself. The green light would never go to pulsing amber by itself. The disk would spin down and the display go off, but not the machine.

Recently I installed MacOS 9.1 and still the behavior is the same. Disk will spin down and display go off after a while, but the green power light stays on (and the fans, etc.).

Is there some magic combination I have to use to get the machine to automatically go completely to sleep (pulsing amber power light)??

Thanks,
Martin

Martin,

I had problems with sleep on my G4/450 until I put some software called Power Manager (by DssW) to use. It does everything Energy Saver is supposed to do, and more (never had much luck with Energy Saver, going all the way back to a 9500/132 running OS 8.x). Power Manager works well with a related piece called Sleep Monitor. You should check into these.

Good luck!
Eric
