I have a powerbook, and when plugged in, is it ok to put the processor to highest? I'm not really good with remembering these techs, and I kept it at automatic because I thought it would get too hot or so. It's on automatic now, if I change it, would I notice some speed? Also, I heard about the computer cleaning or something at 3 AM... kinda like defrag in windows. Does it do that when it's asleep? Should you keep your computer on all night one day to achieve the cleaning?
thanks
