Using battery power
WARNING! To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
The computer runs on battery power whenever it is not plugged into external AC power. Computer
battery life varies, depending on power management settings, running programs, display brightness,
external devices connected to the computer, and other factors. Whenever the computer is plugged into
AC power charges the battery and also protects your work in case of a power outage. If the computer
contains a charged battery and is running on external AC power, the computer automatically switches
to battery power if the AC adapter is disconnected on the computer or an AC power loss occurs.
NOTE: When you disconnect AC power, the display brightness is automatically decreased to save
battery life.
