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 48. 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 shut down your PowerBook and replace the battery with a charged one. 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 47). Battery Battery LEDs If the battery icon in the Finder menu bar is set to show the percentage of charge, you may sometimes notice that the battery does not maintain a full charge of 100% when the power adapter is attached. When the battery level eventually drops below 95 percent, it will charge all the way to 100 percent. This saves battery life as charging is not continuously cycled on and off. 46 Chapter 3 Using Your Computer

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 48.

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 shut down your PowerBook

and replace the battery with a charged one.

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 47).

If the battery icon in the Finder menu bar is set to show the percentage of charge, you

may sometimes notice that the battery does not maintain a full charge of 100% when

the power adapter is attached. When the battery level eventually drops below 95

percent, it will charge all the way to 100 percent. This saves battery life as charging is

not continuously cycled on and off.
