Using the power meter
The power meter allows you to quickly access power settings and view the remaining battery charge.
● To display the percentage of remaining battery charge and the current power plan, move the
pointer over the Power Meter icon, at the far right of the taskbar.
● To access Power Options, or to change the power plan, click the Power Meter icon and select
an item from the list.
Different power meter icons indicate whether the computer is running on battery or external power.
The battery icon displays a message if the battery reaches a low or critical battery level.
Running on battery power
When a charged battery is in the computer and the computer is not plugged into external power, the
computer runs on battery power. If the computer has a charged battery installed and the AC adapter
is disconnected from the computer, the computer automatically switches to battery power and the
display brightness decreases to conserve battery life. The battery in the computer slowly discharges
when the computer is off and unplugged from external power.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the computer, and other factors.
