Powermac G5 won't sleep properly AGAIN

I upgraded to 10.5.8 and my G5 won't sleep anymore. I had this problem before and after one upgrade, it started working fine. The problem is back. I tried deleting com.apple.PowerManagement.plist as was suggested in a thread but that didn't work. Anyone have any ideas?

Powermac G5, Mac OS X (10.4.1)

I wonder why you wouldn't wait longer then that to make sure you were not passing something on to the new OS?

Yeah maybe the iMac was still contagious ....And needed 48 hrs in quarantine.

Ok. I fixed the problem again.

This time I had a process/program(LittleSnitch) attempting to spawn every 10 seconds or less. I thought I had it disabled under Leopard, but perhaps it still loaded something into memory and sat around idle. Or Snow Leopard awakened it. Anyway I believe the version I had is incompatible with Snow Leopard and that was probably was this LittleSnitch process was stuck in an endless loop of trying to load or spawn.

I downloaded the newest SL-compatible version and then uninstalled it. Problem solved.

Of note is the computer and display and set to sleep at 1 minute for testing. Display sleeps at 1 minute, but computer takes a few extra minutes to sleep.
