Battery-Conservation Tips

The amount of work time your iBook G4 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.

•Quit open applications that you are not using.

•If you have an AirPort Extreme Card or Bluetooth module installed, turn AirPort or Bluetooth off when not in use. (Use the AirPort and Bluetooth status icons in the menu bar. If these icons don’t appear in the menu bar, you can turn them on in the AirPort and Bluetooth panes of System Preferences.)

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

•Reduce screen brightness using the brightness controls on the iBook G4 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 iBook G4 to sleep after inactivity of five minutes or less.

To further save battery power, select the following options in the Energy Saver pane of System Preferences:

•Set your computer to modify its processor speed based upon the required amount of processing activity. In the Energy Saver pane of System Preferences, click Show Details to see the settings. Choose Battery Power from the “Settings for” pop-up menu, click Options, and choose Automatic from the Processor Performance pop-up menu. (To set your computer to use its highest processing speed at all times, choose Highest from the Processor Performance pop-up menu.)

•To conserve battery life the longest, choose Longest Battery Life from the Optimize Energy Settings pop-up menu.
