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.
