Securing Your Computer
91
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:
Computers shipping into China are not equipped with the TPM feature.
NOTE:
The TPM feature may not be supported in all countries.
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.
