The computer just stopped.

mThe computer may have gone to sleep. Press any key on the keyboard (except Caps Lock) to wake it again.

mThe battery may have drained so far that the computer has put itself to sleep to protect the contents of RAM. Plug in the power adapter, wait 15 minutes, and then turn the computer on again.

mThe computer may have “crashed” due to temporary software problems. Click the Restart button on the screen (if you see one), or use a paper clip or similar object to press the reset button on the computer’s back panel. If you use these methods, you will lose any work you have not saved.

The computer is very hot.

mIt is normal for the computer to be warm to the touch while you are using it, especially on the side beneath the keyboard. If the computer seems unusually hot, try the following:

m plug in the power adapter

m turn down the screen brightness

m use the Maximum Conservation setting in the PowerBook control panel

m make sure processor cycling is on in the PowerBook control panel

m put the computer to sleep or shut it down
