When the battery pack is connected, you can either use the
power from the battery pack or attach the AC adapter for
unlimited power.
To remove the battery pack, follow these steps:
1. Make sure the computer is off.
2. Disconnect the AC adapter.
3. Turn the computer around so the back is facing you. Make
sure the back of the computer is slightly over the edge of the
desk so you can slide the battery pack down.
4. While pulling the release tabs (on each side of the battery
pack) toward you, press down on the battery pack. Slide the
battery pack down and off the computer.
