hittade det här hos Apple...från manualen för PB G3
------------------------
"The method of resetting you should always try first is to press the Command, Control, and Power keys simultaneously.
If the computer does not start up, connect the power adapter (if it is not already connected) and press the reset button on the back panel.
If the reset described in the previous paragraph does not start up the computer, remove the battery and unplug the power adapter and hold in the reset button for 30 seconds.
Then reconnect the power adapter and put in the battery and try starting up again. "
