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, access the Control Panel, click
Power
Options
, and then click the
Power Meter
tab.
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.
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 "Configuring Power Management
Settings" on page 44.)
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 (see "Checking the Battery Charge" on page 42) before you insert
the battery into the computer. You can also set power management options to alert you when the
battery charge is low. See "Configuring Power Management Settings" on page 44 for information
about accessing the
Power Options Properties
window.
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.
