SECURITY CABLE SLOT — Lets you attach a commercially available antitheft device

to the computer (see "Security Cable Lock" on page 95).

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.

AIR VENTS — The computer uses an internal fan to create airflow through the vents,

which prevents the computer from overheating. The computer turns the fan on when the computer gets hot. Fan noise is normal and does not indicate a problem with the fan or the computer.

HARD DRIVE — Stores software and data.

XPRESSCARD SLOT — Supports one ExpressCard. The computer ships with a

plastic blank installed in the slot. For more information see "Using ExpressCards" on page 79.

a wireless local area network (WLAN) in your vicinity. You can also use it to rapidly turn off or on any wireless devices such as WLAN cards and internal cards with Bluetooth wireless technology (see "Dell Wi-Fi Catcher™ Network Locator" on page 94).
