Trusted Platform Module (TPM) (on selected models)
The TPM, or Trusted Platform Module, is a security hardware device on the system board that will hold
computer-generated keys for encryption. It is a hardware-based solution that an help avoid attacks by hackers
looking to capture passwords and encryption keys to sensitive data. The TPM provides the ability to the PC or
notebook to run applications more secure and to make transactions and communication more trustworthy.
The security features provided by the TPM are internally supported by the following cryptographic capa-
bilities of each TPM: hashing, random number generation, asymmetric key generation, and asymmetric
encryption/decryption. Each individual TPM on each individual computer system has a unique signature
initialized during the silicon manufacturing process that further enhances its trust/security effectiveness.
Each individual TPM must have an Owner before it is useful as a security device.
TPM Applications
TPM is useful for any customer that is interested in providing an addition layer of security to the com-
puter system. The TPM, when bundled with an optional security software package, can provide overall
system security, file protection capabilities and protect against email/privacy concerns. TPM helps
provide security that can be stronger than that contained in the system BIOS, operating system, or any
non-TPM application.
IMPORTANT! Use your TPM
application’s “Backup” or
“Migration” function to backup your
TPM security data.
The TPM is disabled by default. Use BIOS setup to enable it.
Enabling TPM Security
Enter BIOS Setup (press [F2] on system startup).
Set TPM Security to [Yes] in BIOS setup
Security > Trusted Computing.
Clearing TPM Secured Data
When Supervisor Password is installed,
Clearing the TPM will appear. Use this item
to clear all data secured by TPM. (You have
to restart the Notebook PC after setting the
password to see the security clear option.)
IMPORTANT! You should routinely
backup your TPM secured data.
