30 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.
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.
