If you own a PowerBook Duo 230
If you own a PowerBook Duo 230 and want to recondition your battery, you
must fully drain and then fully recharge the battery. Follow these steps:
1 Use the computer as you normally would, but ignore the low-power messages that
appear on the screen.
Make sure to save your work when you see the low-power messages.
2Allow the computer to go to sleep automatically after the third low-power message.
3 Recharge the battery completely before using that battery again.
See “Recharging the Battery” earlier in this chapter for help.
Maximizing work time
Your PowerBook’s battery can provide between 2 to 4 hours of work time
before you need to recharge. The actual work time available depends on what
equipment and power-saving features you’re using.
Ways to conserve battery power
Notice the battery consumption rate that is displayed in the Battery Monitor
module of the Control Strip when you are running your PowerBook off the
battery. When it points to the left, you are conserving battery power and will
have more work time from your battery. To conserve battery power, follow
these tips:
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.
m Tu r n down the screen brightness (¤) whenever possible. At its brightest
level, the screen consumes about a third of the power your computer is
using.
m Keep virtual memory turned off in the Memory control panel.
m If your computer has 8 MB of memory or more, you can use a RAM disk
as your startup disk to minimize hard disk use.
