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+f10 hotkey or reconnect the AC adapter.
