WARNING
: Do not block, push objects into, or allow dust to accumulate in the air
vents. Do not store your Dell 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. 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.
