security cable slot — Lets you attach a commercially available antitheft device to the computer. For
more information, see
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.
