Attaching the Battery Slice to Your Laptop
1. While holding the laptop at a 30-degree angle to the battery slice, set the slots on the bottom of the laptop onto the battery slice hooks, and then
lower the back of the laptop onto the battery slice. The laptop docking connector should engage the battery slice docking connector.
2. Press the laptop onto the battery slice until you feel a click to indicate that the laptop is firmly seated.
3. Turn on the laptop.
Detaching the Battery Slice From Your Laptop
1. Before you detach the battery slice from your laptop, save and close any open files, and exit any open programs.
2. Set your laptop power management settings so that the laptop does not enter sleep, standby, or hibernate mode when you close (lower) the display:
Microsoft ® Windows ® XP

NOTICE: When you disconnect the Dell AC adapter cable from the laptop, grasp the connector, not the cable itself, and pull firmly but gently to
avoid damaging the cable. When you wrap the AC adapter cable, ensure that you follow the angle of the connector on the AC adapter to avoid
damaging the cable.
