TPM_E_PCP_DEVICE_NOT_READY

TPM_E_PCP_DEVICE_NOT_READY means the Microsoft Platform Crypto Provider cannot use the TPM yet because the device is not fully provisioned or ready. It is a readiness-state error, not proof that the TPM hardware is permanently defective.

What to check

Collect the current TPM state before changing configuration: present, enabled, activated, ready, and lockout status.
Check whether Windows reports a restart, shutdown, or physical-presence action as part of TPM provisioning.
If the state changed after firmware or BIOS updates, review the OEM instructions before attempting any reset.
