Apple PowerBook (500 Series) - Manual (Page 45)

Working with an external monitor
For information on displaying the menu bar on the external monitor or using
an external monitor for presentations, see the “Monitors” topic of Macintosh
Guide, available in the Guide (h) menu.
Note: The backlight 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 backlight dimming, see the “Batteries & Power” topic of
Macintosh Guide, available in the Guide (h) menu.

adapter from the port.
