NOTICE: Before you buy an antitheft device, ensure that it will work with the security cable slot.
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.
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.
IEEE 1394 connector — Connects devices supporting IEEE 1394 high-speed transfer rates, such as some digital video cameras.
