Apple MacBook Pro (17-inch) - Manual (Page 78)

78 Chapter 3 Using Your MacBook Pro
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.
 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 MacBook Pro
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 MacBook Pro to sleep after inactivity of five minutes or less.
 Your MacBook Pro is preset to automatically reduce its processing speed during
periods of low processing activity when using battery power, thus reducing power
usage. The setting that determines this is the Normal option in the Optimization
pop-up menu of the Energy Saver pane of System Preferences. During periods of
high processing activity, your computer will automatically switch to a higher
processing speed. To conserve the most battery life, choose Better Battery Life from
the Optimization pop-up menu. However, choosing this option may affect your
computer’s performance. To set your computer to use its highest processing speed at
all times, choose Better Performance.
