Bit confused by the thread below, "Powerbook won't wake up"; there are no posts in the thread!
Anyway, I got a new 15" Powerbook last week, and twice now after putting it to sleep (by simply closing the lid), in the morning I lift the lid and nothing happens (blank screen, neither space bar nor power button do anything). The situation is rectified by Command+Ctrl+power button, but is there something I can do (or should do) to amend this?
