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, check the Power Meter in
Power Options. See "Accessing Power Options Properties" on page 18.
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. You can
install an optional second battery in the media bay to significantly increase
operating time.
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 17 for information about accessing
Windows Power Options Properties or Dell QuickSet, which you can use
to configure power management settings
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 (see "Checking the Battery Charge" on page 16). You can also set
power management options to alert you when the battery charge is low (see
"Configuring Power Management Settings" on page 17).
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.
