Control Strip. If the gauge is to the right, then your computer is consuming
battery power at a rapid rate.

Conservation setting in the PowerBook control panel, or work with the
power adapter plugged in.

Macintosh systems) not designed for PowerBooks. Make sure to use only
low-power input devices (marked with the icon

program is open. Quit your communications program if you aren’t using it.

AppleTalk in the Chooser or in the AppleTalk Switch module of the
Control Strip.
