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™ Tablet-PC 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, check the Power Meter in
Power Options (see “Accessing Power Options Properties” in your User’s Guide.)
NOTE: Battery operating time varies depending on operating conditions.
NOTE: It is recommended that you connect your computer to an electrical outlet
when writing to a CD or DVD.
Operating time on battery power is significantly reduced when you perform
operations including, but not limited to, the following:
• Using optical drives.
• Using wireless communications devices, PC Cards, Express Cards, 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” in your
User’s Guide
for information about
accessing Windows Power 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.
