I don't know if anybody has run into this problem before but my computer won't go to sleep anymore with 10.4.4. I hear the fans shut down along with the hard drive and the mouse and keyboard capabilities are disabled. That's as far as it goes. This all started after I installed Microsoft's USB mouse drivers(Bluetooth mouse). I wiped the hd and did a fresh install after trying to repair permissions. So, with a new, clean OS installed I figured it would work without a hitch, right? Wrong. Not only will it not go to sleep, I can't get the clock to display even after turning the options on in system preferences. Anybody have any suggestions?
