Business PC Secure Boot System: TPM state conflict | Auckland
Pattern to record: A recovery-key prompt follows a firmware or hardware change.
Record the boot configuration
A managed business PC may depend on an approved Secure Boot policy, TPM state and recovery credentials. Record the exact warning and recent change before resetting firmware or replacing hardware. One possible explanation is that stored platform measurements no longer match encryption or security expectations.
Preserve recovery options
Security resets can make encrypted data inaccessible without recovery credentials. Clearing the TPM without keys can lock away encrypted data.
Firmware and hardware checks
- Record encryption status and approved policy before changing TPM or Secure Boot settings.
- Confirm recovery credentials and review the precise change before resetting anything.
Recovery and startup checks
If the checks support this cause, restore the intended firmware state or re-enrol security using authorised credentials. Verification should cover authorised sign-in, restart, updates, encryption status and managed applications.
