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 models only) on page 35.

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

time gradually decreases as the battery storage capacity naturally degrades.
Tips for maximizing battery discharge time:
●
Lower the brightness on the display.
