I'm running my powerbook while connected to a power adaptor, with the current energy settings to "never" put the computer to sleep. I haven't ever had problems with this, but now all of a sudden, it has started to happen... the computer goes to sleep after about five minutes. Strange... It's becoming bothersome now because I use a Logitech Bluetooth Keyboard and Mouse, so I can't wake it from sleep with those. any ideas?
