Using power management
Power management is a collection of system settings that manages how the computer uses power.
Power management can help you conserve power or maximize performance.
You can customize power management settings.
Viewing the current power management settings
Right-click the Power icon in the notification area, at the far right of the taskbar, and then click
Preferences.
Changing the current power management settings
1. Right-click the Power icon in the notification area, at the far right of the taskbar, and then click
Preferences.
2. Change the settings on the On AC Power tab, On Battery Power tab, and General tab, as
needed.
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
Your computer includes 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 battery that is the sole power source for the computer can cause loss of
information. So before removing the battery, save your work and initiate Hibernation, or shut down the
computer through the operating system.
To remove 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.
