Securing Your Computer: Dell Latitude ATG D620 User's Guide
If you enter the wrong password, a message tells you that the password is invalid. Press <Enter> to try
again.
If you do not enter the correct password in three attempts, the computer tries to start from another
bootable device if the
Boot First Device
option in system setup is set to allow start-up from another
device. If the
Boot First Device
option is not set to allow the computer to start from another device,
the computer returns to the operating state it was in when you turned it on.
If the hard drive password, the external hard-drive password, and the primary password are the same,
the computer prompts you only for the primary password. If the hard drive password is different from
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.
Trusted Platform Module (TPM)
NOTE:
The TPM feature may not be available in certain
regions.
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.

a. Restart the computer and press <F2> during the Power On Self Test to enter the
system setup program.
