Trusted Platform Module (TPM)

NOTE:

Computers shipping into China are not equipped with the TPM feature.

NOTE:

The TPM feature supports encryption only if the operating system supports TPM. For more information, see

the TPM software documentation and the help files that came with the software.

TPM is a hardware-based security feature that can be used to create and manage computer-generated

encryption keys. When combined with security software, the TPM enhances existing network and

computer security by enabling features such as file protection capabilities and protected e-mail. The

TPM feature is enabled through a system setup option.

NOTICE:

To secure your TPM data and encryption keys, follow the backup procedures documented in the

Broadcom Secure Foundation Getting Started Guide

. In the event of these backups being incomplete, lost, or

damaged, Dell will be unable to assist in the recovery of encrypted data.
