Using a Battery

Battery Performance

NOTE: For 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 battery installed at all times. One battery is supplied as standard equipment in
the battery bay.
NOTE: Because the battery may not be fully charged, use the AC adapter to connect your new computer to an
electrical outlet the first time you use the computer. For best results, operate the computer with the AC
adapter until the battery is fully charged. To view battery charge status, click the Start button, point to Control
Panel Power Options, and click the Power Meter tab.
NOTE: Battery operating time (the time the battery can operate the computer) 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 optical drives
Using wireless communications devices, ExpressCards, media memory cards, or USB devices
Using high-brightness display settings, 3D screen savers, or other power-intensive programs such
as complex 3D graphics applications
Running the computer in maximum performance mode (See "Power Management Modes" on
page 45.)
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 you insert the battery into 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 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. Page 43 Monday, February 6, 2006 2:24 PM
