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.
l
Attach a commercially available antitheft device to the security cable slot on the back of the 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.
Trusted Platform Module (TPM)
TPM is a hardware-based security feature that can be used to create and manage computer-generated encryption keys. When combined with security

feature is enabled through a system setup option.

Security Center help file. In the event of these backups being incomplete, lost, or damaged, Dell will be unable to assist in the recovery of encrypted
data.
