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 main 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, place the mouse
cursor over the battery icon in the Windows notification area.
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 media.
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.
l
Using wireless communications devices, ExpressCards, media memory cards, or USB devices.
l
Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as complex 3D graphics applications.
l
Running the computer in maximum performance mode (see
l
Options Properties or Dell QuickSet, which you can use to configure power management settings).
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 batteries 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.
