Padlock Ring and Security Cable Slot
Use one of the following methods to secure your computer:
l Use a padlock alone or a padlock and looped security cable with the padlock ring.
A padlock alone prevents the computer from being opened.
A security cable looped around a stationary object is used in conjunction with a padlock to prevent unauthorized movement of the computer.

device contains instructions for installing it.
