Chromebook Reset TPM Error

Modified on Mon, 12 Mar 2018 at 08:35 AM

First how do you know if the chromebook has a TPM error?


If your chromebook automatically boots into the "recovery mode" (or the screen with the Yellow exclamation point) hit "tab" on your keyboard.  Look next to recovery_reason in the second line of text. If you see "TPM Error in read-only firmware", you will need to apply the fix below.




The TPM fix:


You may need to repeat steps (1-3) approx. 20-25 times to clear the TPM error but it usually works within 6-10 attempts.


  1. Power on the Chromebook and leave it on for approx. 30 sec

  2. Then turn it off by holding the "power" button down for approx. 7 seconds

  3. When the Chromebook is off, wait a couple seconds and push the power button once to turn back on


Remember, you will need to repeat steps 1-3. You will know you have successfully cleared the TPM error when the chromebook boots up normally and/or returns back to the login screen.
