Note: The screen-dimming feature in the PowerBook control panel turns the
screen brightness down to a low level when you haven’t used the computer for
a few minutes. (You can think of dimming as “screen sleep.”) Dimming also
affects the external monitor. When you move your finger on the trackpad or
press a key on the keyboard, the brightness is restored on both screens. For
more information on screen dimming, see the “Batteries & Power” topic area
of Mac OS Guide, available in the Guide (h) menu.
