Understanding Battery Conservation Tips
For the best conservation of battery power, do the following:
 Disconnect USB or FireWire devices when they are not in use.
 Quit open applications that you are not using.
 Turn off AirPort or Bluetooth when they are 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 Network 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 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 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 Better Battery Life from the Optimization
pop-up menu. Be aware that choosing this option will adversely affect your
applications’ performance.
