Security Cable Slot and Padlock Ring

To the right of the fan vent on the back of the computer is
a security cable slot (see Figure 1-3) for attaching a com-
mercially available antitheft device. Antitheft devices for
personal computers usually include a segment of galva-
nized cable with an attached locking device and
associated key. To prevent unauthorized removal of your
computer, loop the cable around an immovable object,
insert the locking device into the security cable slot on
the back of your computer, and lock the device with its
associated key. 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 your computer.
