Battery Performance

NOTE: For information about the Dell warranty for your computer, see the Product

Information Guide or separate paper warranty document that shipped with your

computer.

For optimal computer performance and to help preserve BIOS settings,

operate your Dell portable computer with the main battery installed at all

times. One battery is supplied as standard equipment in the battery bay.

NOTE: Because the battery may not be fully charged, use the AC adapter to

connect your new computer to an electrical outlet the first time you use the

computer. For best results, operate the computer with the AC adapter until the

battery is fully charged. To view battery charge status, click Start

Battery operating time varies depending on operating conditions. You can

install an optional second battery in the media bay to significantly increase

operating time.

Operating time is significantly reduced when you perform operations

including, but not limited to, the following:

• Using optical drives

• Using wireless communications devices, PC Cards, ExpressCards, media

memory cards, or USB devices

• Using high-brightness display settings, 3D screen savers, or other power-

intensive programs such as complex 3D graphics applications

Running the computer in maximum performance mode (see "Configuring

Power Management Settings" in your

User’s Guide

).

NOTE: Battery operating time (the time the battery can hold a charge) decreases

over time. Depending on how often the battery is used and the conditions under

which it is used, you may need to purchase a new battery during the life of your

computer.

NOTE: It is recommended that you connect your computer to an electrical outlet

when writing to a CD or DVD.
