).
CAUTION:
Any attempt to remove an installed TPM from the system board breaks or disfigures
the TPM security rivet. Upon locating a broken or disfigured rivet on an installed TPM,
administrators should consider the system compromised and take appropriate measures to ensure
the integrity of the system data.
When installing or replacing a TPM, observe the following guidelines:
•
Do not remove an installed TPM. Once installed, the TPM becomes a permanent part of the system
board.
•
When installing or replacing hardware, HP service providers cannot enable the TPM or the encryption
technology. For security reasons, only the customer can enable these features.
•
When returning a system board for service replacement, do not remove the TPM from the system board.
When requested, HP Service provides a TPM with the spare system board.
•
Any attempt to remove an installed TPM from the system board breaks or disfigures the TPM security
rivet. Upon locating a broken or disfigured rivet on an installed TPM, administrators should consider the
system compromised and take appropriate measures to ensure the integrity of the system data.
•
When using BitLocker™, always retain the recovery key/password. The recovery key/password is
required to enter Recovery Mode after BitLocker™ detects a possible compromise of system integrity.
•
HP is not liable for blocked data access caused by improper TPM use. For operating instructions, see the
encryption technology feature documentation provided by the operating system.
