Maximizing work time
Your PowerBook’s battery can provide up to 3 hours of work time
before you need to recharge it. The actual work time available
depends on what equipment you’re using with your computer
and what steps you take to conserve power while you work.
Ways to conserve battery power
The more of these steps you take, the longer you can use your
battery before recharging it.
m Turn down the screen brightness whenever possible. At its
brightest level, the screen consumes about a third of the
power your computer is using.
m Adjust the battery conservation settings in the PowerBook
control panel for maximum conservation: set the battery
conservation slider at Maximum Conservation; keep processor
cycling turned on. The rest of this section describes these
settings in detail.
m Keep virtual memory turned off in the Memory control panel.
m Quit any program that uses a modem unless you’re using the
program for telecommunication. As long as the program is
open, your modem is consuming power.
m If you’re working near an electrical outlet, plug in the power
adapter.
m If you aren’t using the computer, put it to sleep and plug in
the power adapter.
