Security Cable Lock
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.
