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 from the computer or an AC power loss occurs. NOTE: When you disconnect AC power, the display brightness is automatically decreased to save battery life. For information on increasing or decreasing display brightness, refer to the Getting Started guide. Select computer models can switch between graphic modes to increase battery life. For more information, refer to Switching between graphics modes (select models only) on page 32.

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 from

the computer or an AC power loss occurs.

NOTE:

When you disconnect AC power, the display brightness is automatically decreased to save

battery life. For information on increasing or decreasing display brightness, refer to the
