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 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.
Removing a user-replaceable battery
WARNING! To reduce potential safety issues, use only the user-replaceable battery provided with
the computer, a replacement battery provided by HP, or a compatible battery purchased from HP.
CAUTION: Removing a user-replaceable battery that is the sole power source for the computer can
cause loss of information. To prevent loss of information, save your work or shut down the computer
through Windows before removing the battery.
1. Slide the battery lock latch (1), and then slide the battery release latch (2) to release the battery.
