Using a Battery

Battery Performance

NOTE: Batteries for portable computers are covered only during the initial one-year period of the limited warranty for your computer. For more information about the Dell warranty for your computer, see page 121.

Use a battery to power the computer when it is not connected to an electrical outlet. One battery is supplied as standard equipment in the battery bay.

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

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

•Using optical drives, especially DVD and CD-RW drives.

•Using wireless communications devices, PC Cards, or USB devices.

•Using high-brightness display settings.

•Using 3D screen savers or other power-intensive programs such as 3D games and engineering programs.

•Running the computer in maximum performance mode. See "Power Management" in the Dell Inspiron Help file for more information. To access the help file, see page 16.

You can set power management options to alert you when the battery charge 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 "SAFETY: Battery Disposal" on page 13.

CAUTION: Misuse of the battery may increase the risk of fire or chemical burn. Do not puncture, incinerate, disassemble, or expose the battery to temperatures above 65°C (149°F). Keep the battery away from children. Handle damaged or leaking batteries with extreme care. Damaged batteries may leak and cause personal injury or equipment damage.
