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.
