Trusted Platform Module (TPM)
NOTE: Computers shipping into China are not equipped with TPM.
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 Archive
and Restore section of the EMBASSY 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.
