 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 MacBook Pro

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 light 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. Be aware that 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.
