I have all of my MacBooks set to not sleep while connected to wall current. One keeps getting reset to go back to sleep. That user swears he isn't doing anything like Command-Option-Eject. WoL sometimes bring sit back, usually doesn't. And I constantly see that sleep has been set back to 60. I reset it to 0, and later it's back to 60 again. How can I track down what's doing this?
