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.
