Another caveat to owners of the new Powerbooks: As I just found out, for some reason Apple in its infinite wisdom set the Energy control so that the Powerbooks will never go to sleep either on the battery or on the adaptor. I just discovered this today when I walked into my office that my computer had been on all night and the display showed the log-in window. The temperature was at 125° (but I could not hear any fans going...hmmm!) The System logs said that it rebooted (Macaroni's does this after running Cron scripts) at 3:00 am and tried to go to sleep on numerous occasions, but that sleep was not enabled on my machine. So, better check Energy Control in the System Preferences and see that sleep is enabled. jg
