Battery When the external power adapter is not connected, your computer draws power from its battery. Depending on the applications you use and external devices connected to your PowerBook, you may find that the length of time that you can run your PowerBook off one battery charge varies. Turning off certain features such as AirPort Extreme or Bluetooth® wireless technology can help to conserve battery charge. For more information about using your battery, see "Battery-Conservation Tips" on page 49. You can determine the charge left in your battery by looking at the battery level indicator lights on the battery itself. Press the button next to the lights and the lights glow to show how much charge is left in the battery. The indicator lights remain lit for a few seconds after you press the button. You can check the charge with the battery in or out of your PowerBook. If your battery runs low while you are working, you can put your PowerBook to sleep and replace the battery with a charged one. The internal backup battery provides enough power to maintain the contents of RAM for up to three minutes while you change the battery. Note: If you have installed additional memory in your PowerBook, the backup battery may provide power for less than three minutes. Also, changing batteries several times in a short period can shorten the length of time the backup battery can maintain data if the backup battery hasn't had time to fully recharge. Important: If only one flashing light is on, very little charge is left. If no lights are visible, the battery is completely drained and the computer will not start up unless the power adapter is connected. Plug in the power adapter to let the battery recharge, or replace the drained battery with a fully charged battery (see page 48). Battery LEDs Battery Chapter 3 Using Your Computer 47

Using Your Computer

Battery

When the external power adapter is not connected, your computer draws power from

its battery. Depending on the applications you use and external devices connected to

your PowerBook, you may find that the length of time that you can run your

PowerBook off one battery charge varies. Turning off certain features such as AirPort

Extreme or Bluetooth

wireless technology can help to conserve battery charge.

For more information about using your battery, see “Battery-Conservation Tips” on

page 49.

You can determine the charge left in your battery by looking at the battery level

indicator lights on the battery itself. Press the button next to the lights and the lights

glow to show how much charge is left in the battery. The indicator lights remain lit for

a few seconds after you press the button. You can check the charge with the battery in

or out of your PowerBook.

If your battery runs low while you are working, you can put your PowerBook to sleep

and replace the battery with a charged one. The internal backup battery provides

enough power to maintain the contents of RAM for up to three minutes while you

change the battery.

Note:

If you have installed additional memory in your PowerBook, the backup battery

may provide power for less than three minutes. Also, changing batteries several times

in a short period can shorten the length of time the backup battery can maintain data

if the backup battery hasn’t had time to fully recharge.

Important:

If only one flashing light is on, very little charge is left. If no lights are

visible, the battery is completely drained and the computer will not start up unless the

power adapter is connected. Plug in the power adapter to let the battery recharge, or

replace the drained battery with a fully charged battery (see page 48).
