Battery packs

When a charged battery pack 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 pack 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.

disconnect AC power. To increase display brightness, use the

battery pack in the computer whenever the computer is plugged into external AC power enables the

plugged into external power.
