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/dual graphics (select products only) on page 38.
