indicate the following:
A
IR VENT The computer uses an internal fan to create airflow through the
vents, which prevents the computer from overheating.
HINT: The computer
turns on the fans when the
computer gets hot. The
fans may make 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. 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.
