Air Vent
The computer uses an internal fan to create airflow through the vents, which prevents the computer from
overheating.
NOTE: The computer turns on the fans only when the computer gets hot. The fans may make a noise,
which is normal and does not indicate a problem with the fans or the computer.
CAUTION: Do not block, push objects into, or allow dust to accumulate in the air vents.
Doing so can damage the computer or cause a fire.
