I'm just going to cut to the chase. If all of you could please open up Console (Applications>Utilities) and then put your computer to sleep and then wake it up and then search for: IOBluetoothHCIController::restartShutdownWL this is a wake from sleep Basically my computer has been waking up even it's closed after it falls asleep. I took it to the Apple store but since i'm out of warranty they didn't really do a full check but said that error means that the Bluetooth controller is causing it to wake up. But googling that, i found that a lot of people get that message and supposedly it's normal?? I'm just trying to narrow this down because it's extremely annoying. Thank you SO SO much, fellow PowerBook owners!! Also, i'm running a 15" 1.67 ghz pb with the latest version of Tiger. so i guess if you have that you're the best candidate.
