Setting up Your Battery Slice
WARNING:
The AC adapter works with electrical outlets worldwide. However,
power connectors and power strips vary among countries. Using an incompatible
cable or improperly connecting the cable to the power strip or electrical outlet
may cause fire or damage the equipment.
CAUTION:
Always use the Dell AC adapter that came with your computer. If you
use any other commercially available AC adapter—or the AC adapter from earlier
models of Dell computers—you may damage the battery slice or the computer.
CAUTION:
Use the battery slice with your computer only. If you use a battery slice
from other models of Dell computers you may damage the battery slice or the
computer.
CAUTION:
When you disconnect the Dell AC adapter cable from the computer,
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.
1 Connect the AC adapter to the AC adapter connector on your computer.
2 Before you dock or undock your computer from the battery slice, save and
close any open files, and exit any open programs.
