TPM Activation
Trusted Platform Module (TPM) is an industry standard cryptographic module that provides attestation, integrity metrics
and reporting, and a secure key hierarchy. Dell client systems use TPM to verify if the state of the system has changed
between two boot cycles.
To activate and check the TPM activation:
1. If not set, set the BIOS password on the system. Type:
cctk --setuppwd=<new-BIOS-password>
2. If not enabled, enable TPM. Type:
cctk --tpm=on
