MEMORY MODULE COVER — Covers the compartment that contains the memory modules. See page 77.
FAN — The computer uses an internal fan to create airflow through the vents, which prevents the
computer from overheating.
NOTE: 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.
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.
