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

IMPORTANT: Do not attempt to replace your computer battery, which is installed and sealed at the factory. A broken battery seal voids your warranty.

Your computer has an internal rechargeable battery that can be replaced only by an authorized service provider. For information about keeping your battery in good condition, see Conserving battery power on page 49.

To monitor the status of your battery, or if the battery is no longer holding a charge, run Battery Check in HP Support Assistant. To access battery information, select the HP Support Assistant app from the Start screen, and then select Battery and performance. If Battery Check indicates that your battery should be replaced, contact HP Customer Support.

NOTE: If your computer is unresponsive and you are unable to use the recommended shut down procedures, press and hold the power button and the mute button to shut down your computer.
