| Powerbook G4 won't boot properly/wake I am currently running a 15" Powerbook G4 1.67, 1GB ram, latest update for 10.5. Yesterday my computer randomly went to sleep and wouldn't wake up. I forced it to shut down and then tried rebooting it. It started up, but went to sleep before even getting to the login screen. I have searched the internet, this website, and the apple support site to try and fix the problem. I have tried resetting the PMU (although I don't know if I did that correctly), leaving it to rest without any battery or AC power hooked up to it, and the CMD + ALT + P + R reset all to no avail. It seems like the general outcome for random sleep problems hasn't been too good, but any other help tips would be greatly appreciated. Thank you.  |

| To reset the PMU, you need to turn off the computer, then disconnect the battery and power cable. Once the computer is shut down, press and hold the power button for 5 seconds, then replace the battery and cable and restart. You should make sure your battery holds a charge and your power adapter is working correctly as well. When you say sleep - do you mean the light is blinking, or the screen goes blank? They aren't nessisarily the same thing.
