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. 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.
