Using a Battery Battery Performance CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide. For optimal computer performance and to help preserve BIOS settings, operate your Dell™ portable computer with the main battery installed at all times. Use a battery to run the computer when it is not connected to an electrical outlet. One battery is supplied as standard equipment in the battery bay. NOTE: Battery operating time (the time a 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 module bay to significantly increase operating time. For more information about the second battery, see page 41. Operating time is significantly reduced when you perform operations including, but not limited to, the following: • Using DVD, DVD-R, and CD-RW drives • Using wireless communications devices, PC 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 NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD. 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 lithium-ion 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." Using a Battery 33
