When the battery power is running low, both the battery and power indicators blink.

When the computer is directly connected to AC power and has a battery pack in the battery bay, it uses power from the AC outlet.

See “Using a Second Battery Pack” for information on installing and charging a battery pack in the multipurpose bay.

Keep the battery pack in the computer while it is directly connected to AC power. The battery pack continues to charge while you are using the computer.

If the battery level falls below 10%, you should either attach the AC adapter to recharge the battery or shut down your computer and insert a fully charged battery.
