Running on battery power
WARNING!
To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
When a charged battery is in the computer and the computer is not plugged into external power, the 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.
NOTE:
When you disconnect external power, the display brightness is automatically decreased to conserve
battery charge. Select computer products can switch between graphic controllers to conserve battery charge.
