Battery Performance

CAUTION:

Before you begin any of the procedures in this chapter, follow the safety instructions in the

Product Information Guide.

NOTE:

Batteries for portable computers are covered only during the initial 1-year period of the limited

warranty for your computer. For more 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. Use a battery to run the computer
when it is not connected to an electrical outlet. One battery is supplied as standard equipment in
the battery bay.

NOTE:

Battery operating time (the time a 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.

Battery operating time varies depending on operating conditions. Operating time is significantly
reduced when you perform operations including, but not limited to, the following:

Using DVD+RW/DVD+R drives

Using wireless communications devices, PC Cards, or USB devices

Using high-brightness display settings, 3D screen savers, or other power-intensive programs
such as 3D games

Running the computer in maximum performance mode. For more information, see the

Dell

Inspiron Help file. To access the help file, see page 9.

NOTE:

It is recommended that you connect your computer to an electrical outlet when writing to a CD

or DVD.

You can check the battery charge before or after you insert the battery into the computer. You can
also set power management options to alert you when the battery char
ge is low.

CAUTION:

Using an incompatible battery may increase the risk of fire or explosion. Replace the

battery only with a compatible battery purchased from Dell. The lithium-ion battery is designed to work
with your Dell computer. Do not use a battery from other computers with your computer.

CAUTION:

Do not dispose of batteries with household waste. When your battery no longer holds a

charge, call your local waste disposal or environmental agency for advice on disposing of a lithium-ion
battery. See "Battery Disposal" in the Product Information Guide.
