the primary password, the computer prompts you for both. Two different passwords provide greater

security.

NOTE: The administrator password provides access to the computer, but it does not provide access

to the hard drive when a hard-drive password is assigned.

If the administrative password is installed when the user creates the primary hard-drive password, then

the administrative password can be used in place of the primary hard-drive password. This feature allows

an administrator to unlock password-protected hard drives as long as an administrative password is

installed before deploying the computers.

There are two behaviors associated with this feature that help to preserve the integrity of the hard-drive’s

password:

• The administrative password will only work to unlock a hard drive on the computer on which the

hard-drive password was created. This means a password-protected hard drive cannot be removed

from one computer, placed in a second computer and be unlocked using the administrative password

on the second computer.

• Installing an administrative password on a computer after the hard-drive password has been created

will not enable unlocking of the hard drive using the administrative password.

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.

NOTE: 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. The EMBASSY Security

Center is launched through the pre-installed Dell Control Point software on your computer. In the

event of these backups being incomplete, lost, or damaged, Dell will be unable to assist in the

recovery of encrypted data.
