I have a Dual G4 02' but I have not been able to make my computer go in to a "Deep Sleep" mode. (Deep Sleep is when the computer incl. fans and HD go completely idle and the machine makes no noise.) When my computer goes to sleep, I can hear the HD spin down but the power sup and case fan seem to continue spinning, therefore it is as loud as when it is turned on. Does anyone else have the same problem? Does anyone have any solutions that have helped them?
