Method 1: Enabling TPM Control from OS

  1. Restart your computer. While it boots up, keep pressing the designated BIOS key (usually Del, F2, or Esc) to enter the BIOS setup utility.
  2. Navigate to the Security > TPM Embedded Security page (the path might vary slightly depending on your BIOS version).
  3. Locate the options “RESET of TPM from OS” and “OS Management of TPM”.
  4. Enable these options using the available keys (usually arrow keys and Enter).
  5. Save your changes by pressing F10 and then Enter.
  6. Check if the error persists by attempting to clear the TPM again.
