CAUTION:
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.
NOTICE:
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.
