Different power meter icons indicate whether the computer is running on battery or external power.
The icon also reveals a message if the battery has reached a low or critical battery level.

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
screen 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, screen 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, from the Start screen, type support, select the
HP Support Assistant app, and then select Battery and performance. If Battery Check indicates that
your battery should be replaced, contact support.
Do not attempt to remove or replace the factory-sealed battery. Removing or replacing the battery
could affect your warranty coverage. If the battery is no longer holding a charge, contact support.
When a battery has reached the end of its useful life, do not dispose of the battery in general
household waste. Follow the local laws and regulations in your area for battery disposal.
