 Dell recommends that you attach external devices
only while the computer is turned
off
unless you are instructed otherwise in the documentation for the particular device.
Then turn the computer on before turning on any external devices unless the doc-
umentation for the device specifies otherwise. (If the computer does not seem
to recognize the device, try turning on the device before turning on the
computer.)

On the back of the computer are a security cable slot and padlock ring (see Figure 1-3)
for attaching commercially available antitheft devices. Security cables for personal
computers usually include a segment of galvanized cable with an attached locking
device and key. To prevent unauthorized removal of the computer, loop the cable
around an immovable object, insert the locking device into the security cable slot on
the back of the computer, and lock the device with the key provided. Complete
instructions for installing this kind of antitheft device are usually included with the
device.
NOTE: Antitheft devices are of differing designs. Before purchasing such a device,
make sure it will work with the cable slot on the computer.
The padlock ring allows you to secure the computer cover to the chassis to prevent
unauthorized access to the inside of the computer. To use the padlock ring, insert a
commercially available padlock through the ring and then lock the padlock.
