Error messages

This is where you'll see any relevant error messages about your security processor. Here's a list of the error messages that might appear:

  • A firmware update is needed for your security processor (TPM). Your device's motherboard doesn't appear to support TPM currently, but a firmware update might resolve this. Check with your device's manufacturer to see if a firmware update is available and how to install it. Firmware updates are usually free.

  • TPM is disabled and requires attention. The trusted platform module is probably turned off in the system BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface). Refer to your device manufacturer's support documentation, or contact their technical support, for instructions on how to turn it on.

  • TPM storage is not available. Please clear your TPM. The clear TPM button is on this page. You'll want to make sure you have a good backup of your data before proceeding. 

  • Device health attestation isn't available. Please clear your TPM. The clear TPM button is on this page. You'll want to make sure you have a good backup of your data before proceeding.

  • Device health attestation isn't supported on this device. This means the device doesn't give us enough information to determine why TPM may not be working properly on your device.

  • Your TPM isn't compatible with your firmware and may not be working properly. Check with your device's manufacturer to see if a firmware update is available and how to get and install it. Firmware updates are usually free.

  • TPM measured boot log is missing. Try restarting your device.

  • There is a problem with your TPM. Try restarting your device.

If you still encounter problems after addressing an error message, contact your device manufacturer for assistance.
