I encounter again and again problems with getting my G4 into deep sleep. W/o any recurring reason, the Mac starts to need time to fall into deep sleep (and to fully wake up again). That works as follows: first the monitor gets dark, then the HD spinns down and then a 50 to 90 sec. delay occurs before the fan gets quiet. Wakeup is opposite: after starting the monitor and HD, the Mac needs 50 to 90 s. to update the clock. Nothing helps other than a restart - and that on a Unix system, what a shame... Probabely it has to do with the power mangement. Can anybody explain who to reset the PM on my G4?
