28 About Your Computer
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.
AIR VENTS 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.
