The operating time of a battery, which is the time the battery can hold
acharge, 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,
orUSBdevices.
•High-brightness display settings, 3D screen savers, or other
power-intensive programs like complex 3D graphics applications
andgames.
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

(see Power Management).
