CAUTION: The TPM is not a customer-removable part.
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.
If you suspect a TPM board failure, leave the TPM installed and remove the system board. Contact
an HP authorized service provider for a replacement system board and TPM board.
