Battery Performance

CAUTION:
Before you begin any of the procedures in this section, follow the safety instructions
located in the Product Information Guide.
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. 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. 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 optional second battery, see your User's Guide.
NOTE:
Battery operating time (the time it 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.
