Using battery power

When a charged battery is in the computer and the computer is not plugged into external power, the

computer runs on battery power. When the computer is plugged into external AC power, the

computer runs on AC power.

If the computer contains a charged battery and is running on external AC power supplied through the

AC adapter, the computer switches to battery power if the AC adapter is disconnected from the

computer.

NOTE:

The display brightness is decreased to save battery life when you disconnect AC power. To

increase display brightness, use the

fn+f3

hotkey or reconnect the AC adapter.

You can keep a battery in the computer or in storage, depending on how you work. 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. However, a battery in the computer slowly

discharges when the computer is off and unplugged from external 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.

Computer battery life varies, depending on power management settings, programs running on the

computer, display brightness, external devices connected to the computer, and other factors.

Using Battery Check

Battery Check provides information on the status of the battery installed in the computer.
