Charging a Battery

When the power adapter that came with your computer is connected, the battery recharges whether the computer is off, on, or in sleep. However, the battery recharges more quickly if the computer is off or in sleep. You can monitor the battery charge level using the Battery status icon in the menu bar.

The battery charge level displayed is based on the amount of power left in the battery with the applications, peripheral devices, and system settings (display brightness, Energy Saver settings, and so on) you are currently using. To make more battery power available, close applications and disconnect peripheral devices not in use, and adjust your Energy Saver settings (see the next section).

Battery-Conservation Tips

The amount of work time your PowerBook battery can provide before you need to recharge depends on the applications and peripheral devices you’re currently using and the steps you take to conserve power while you work.

For the best conservation of battery power, do the following:

•Disconnect bus-powered USB or FireWire devices when they are not in use.

•If you have an AirPort Extreme Card installed, turn AirPort off when not in use (use the AirPort status icon in the menu bar).

•Turn off Bluetooth wireless technology when not in use.

•Quit open applications that you are not using.

•Remove CD and DVD discs when they are not in use.

•Reduce screen brightness using the brightness controls on the PowerBook keyboard.

•Set the hard disk to spin down after a short time. In the Energy Saver pane of System Preferences, select the “Put the hard disk to sleep when possible” option.

•Set your PowerBook to sleep after inactivity of five minutes or less.
