The AC adapter converts AC power to the DC power required by the computer. You can connect the AC adapter with your computer turned either on or off. For optimum performance, use only the AC adapter that came with your computer.

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. The computer turns on the fan when the computer gets hot. Fan noise is normal and does not indicate a problem with the fan or the computer

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. 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.
