Apple Macintosh PowerBook 145B - Manual (Page 258)

The computer just stopped.
m The computer may have gone to sleep. Press any key on the
keyboard (except Caps Lock) to wake it again.
m The 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.
m The 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.
m It 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
