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 equipment damage.
CAUTION: When you disconnect the 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.
NOTE: Some devices may not be included if you did not order them.
