12 Quick Reference 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.
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 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 3D
games
• Running the computer in maximum performance mode. See "Configuring Power Management
Settings" on page 14 for information about accessing Windows Power Options Properties or Dell
QuickSet, which you can use to configure power management settings.
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 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.
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.
