Low-Battery Warning
NOTICE:
To avoid losing or corrupting data, save your work immediately after a
low-battery warning. Then connect the Tablet-PC to an electrical outlet, or dock the
Tablet-PC onto an optional battery slice. If the battery runs completely out of power,
hibernate mode begins automatically.
A pop-up window warns you when the battery charge is approximately 90
percent depleted. If both the main battery and the battery slice are installed,
the low-battery warning means that the combined charge of both batteries is
approximately 90 percent depleted. The Tablet-PC enters hibernate mode
when the battery charge is at a critically low level.
You can change the settings for the battery alarms in QuickSet or the Power
Options Properties window. See "Configuring Power Management Settings"
on page 72 for information about accessing QuickSet or the Power Options
Properties window.
Conserving Battery Power
Perform the following actions to conserve battery power:
• Connect the Tablet-PC to an electrical outlet when possible because
battery life is largely determined by the number of times the battery is
used and recharged.
• Place the Tablet-PC in sleep mode or hibernate mode when you leave the
Tablet-PC unattended for long periods of time. See "Power Management
Modes" on page 71.
• Use the Power Management Wizard or the Power Options Properties
window to select options to optimize your computer’s power usage. These
options can also be set to change when you press the power button, close
the display, or press <Fn><Esc>.
NOTE:
See "Configuring Power Management Settings" on page 72 for information
on conserving battery power.
