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.
✎
On select models, the display brightness is automatically
decreased to save battery life when you disconnect from AC
power. To increase display brightness, use the hotkey or
fn+f8
reconnect your AC adapter.
You can keep a battery pack in the computer or in storage,
depending on how you work. Keeping the battery pack in the
computer whenever the computer is plugged into external AC
power enables the battery pack to charge and also protects your
work in case of a power outage.
However, battery packs in the computer slowly discharge when
the computer is turned off. For this reason, the battery pack is not
shipped inside the computer and must be inserted before the
computer can run on battery power.
