About Your Computer
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.
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. 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.
AIR VENTS — The computer uses an internal fan to create airflow through the vents, which prevents the computer
from overheating.
CAUTION:
Do not block, push objects into, or allow dust to accumulate in the air vents. Do not store your
computer in a low-airflow environment, such as a closed briefcase, while it is running. Restricting the airflow
can damage the computer or cause a fire.
NOTE:
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.
