Padlock Ring and Security Cable Slot
Use one of the following methods to secure your computer:
• 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.
• Attach a commercially available antitheft device to the security cable slot on the back of the computer.
NOTE: Before you purchase an antitheft device, make sure that it works with the security cable slot on your
computer.
Antitheft devices usually include a segment of metal-stranded cable with an attached locking device
and key. The documentation that comes with the device contains instructions for installing it.
