computer runs on battery power. When the computer is off and unplugged from external power, the battery
in the computer slowly discharges. The computer displays a message when the battery reaches a low or
critical battery level.
Computer battery life varies, depending on power management settings, programs running on the computer,
screen brightness, external devices connected to the computer, and other factors.
