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
•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.
