I've been semi-curious about this for a while now. I noticed it about a year ago but it's been happening a lot more in recent days... I put my powerbook into sleep. shut the lid, go through the menu. either way. I leave my room. come back a few hours later, open my door, turn the light on *brrtzzzz* PowerBook wakes up. at first I thought there was some kind of motion sensor. Before I fully knew the magic of the PB. But more and more I think its when I turn the lights on. Any ideas to whats causing this? Or is my PowerBook really just psychic. "oh, welcome James. I've prepared a lovely selection of mint After Eights on a tray for you" "cheers computer, chomputer"
