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.
Factory-sealed battery
To monitor the status of your battery, or if the battery is no longer holding a charge, run Battery Check
in Help and Support. To access battery information, select the HP Support Assistant app on the
Start screen, and then select Battery and performance. If Battery Check indicates that your battery
should be replaced, contact support.
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. Turn the computer upside down on a flat surface.
2. Slide the battery release latch (1) to release the battery.
NOTE: The battery release latch automatically returns to its original position.
3. Pivot the battery (2) upward and remove it from the computer.
