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. Keeping the battery in the computer

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. Select computer models can switch between graphic modes to increase battery life. For

more information, see

Switchable graphics (select models only) on page 41.
