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:

1Use 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.

3Recharge 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:

mIf you’re working near an electrical outlet, plug in the power adapter.

mIf you aren’t using the computer, put it to sleep and plug in the power adapter.

mTurn down the screen brightness (¤) whenever possible. At its brightest level, the screen consumes about a third of the power your computer is using.

mKeep virtual memory turned off in the Memory control panel.

mIf your computer has 8 MB of memory or more, you can use a RAM disk as your startup disk to minimize hard disk use.
