Improving Battery Life
The operating time of a battery, which is the time the battery can hold
a charge, varies depending on how you use your laptop computer.
The operating time of your battery significantly reduces if you use:
• Optical drives.
• Wireless communication devices, ExpressCards, media cards,
or USB devices.
• High-brightness display settings, 3D screen savers, or other
power-intensive programs like complex 3D graphics applications
and games.
You can improve the battery performance by:
• Operating the computer on AC power when possible. Battery life
reduces with the number of times the battery is discharged and
recharged.
• Configuring the power management settings using Microsoft Windows
Power Options to optimize your computer’s power usage
(see
Power Management ).
• Enabling the Sleep/Standby and Hibernation features of your computer.
NOTE: The life of the battery decreases over time depending on how
often the battery is used and the conditions under which it is used.
You can configure your the battery-charging behavior to increase the
battery life.
