MEMORY MODULE/WLAN MINI-CARD COVER — Covers the compartment that contains the second memory
module connector (DIMM B) (see "Memory" on page 155).
AIR VENTS — The computer uses an internal fan to create airflow through the vents, which prevents the computer
from overheating.
CAUTION: 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.
