Using Batteries and Module Bay Devices

Using a Battery

Battery Performance

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the

Product Information Guide.

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

NOTE: Battery operating time (the time it 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. With average usage, you may expect from 3 to 4 hours from a single, fully charged battery. You can install an optional second battery in the module bay to significantly increase operating time. For more information about the second battery, see "About the Module Bay" on page 36.

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

Operating time is significantly reduced when you perform operations including, but not limited to, the following:

Using optical drives, especially DVD and CD-RW 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

You can check the battery charge on the bottom of the computer. You can also 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. Read the safety instructions for battery disposal in the Product Information Guide.
