Using a Battery

Battery Performance

 

NOTE: 

For information about the Dell warranty for your computer, see the Product 

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.

•

Using wireless communications devices, ExpressCards, media memory 
cards, or USB devices.

•

Using high-brightness display settings, 3D screen savers, or other power-
intensive programs such as complex 3D graphics applications.

•

Running the computer in maximum performance mode (see "Configuring 
Power Management Settings" on page 47 for information about accessing 
Windows Power Options Properties or Dell QuickSet, which you can use 
to configure power management settings).
