when i shut my powerbook's lid it goes to sleep then wakes then sleeps then wakes rapidly until a few minutes when it stops and goes to sleep... what's wrong with it?! and everytime it wakes it would go like "EWRWERKACH" kinda noise, but it did that before also.. also when you mouse over the dock is makes a small click noise but if you reposition the dock it's not on the bottom but just where the dock is?>
