You can connect the AC adapter with your computer turned on or off. 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.

A I R V E N T S - The computer uses an internal fan to create airflow through the vents, which prevents the computer from overheating. The computer turns the fan on when the computer gets hot. Fan noise is normal and does not indicate a problem with the fan or the computer.
