Windows 10: Initialisation of the Trusted Platform Module (TPM) failed

When I booted the laptop yesterday I was no longer able to login using my windows pin. I had to login using the password, can't get the pin to work again. In event viewer under windows logs>system have continuously:

event ID 27 'The initialisation of the Trusted Platform Module (TPM) failed. The TPM may be in failure mode. To allow diagnostics, contact the TPM manufacturer with the attached information'

I can easily log on to windows still just using the password and not the pin. Hasn't yet affected any other function of the laptop.

Its an older Lenovo ideapad700, Intel Core(TM) i7-6700HQ [email protected] 2.gGHZ, 16g ram, SSD hard disk

Windows version 1909(OS Build 18363.1016)

All windows updates are up to date, I do have the option to download and install win 10 vesion 2004, not sure if that would help?

Not sure if this is a real problem, or I could just ignore it?
Thanks in advance

:)

 

Bitlocker and Trusted Platform Module problems

We appreciate the screenshot you sent.

This issue usually occurs because the Trusted Platform Module (TPM)
uses the manufacturer driver and not the Windows built-in Trusted Platform Module driver.

To resolve this, you can manually uninstall and reinstall Trusted Platform Module. To do so, see the steps below:

• Open Device Manager on the device on which you are experiencing the issue
• Uninstall the Trusted Platform Module driver.

Give us an update after following the troubleshooting steps provided.

 

Verify Trusted Platform Module (TPM) Chip on Windows PC


Something I came across not long ago, is Firmware-based Trusted Platform Modules (fTPM). Whereas before in order to take advantage of a TPM you needed to have a physical TPM chip soldered to the motherboard, that seems to have changed at some point. You can now have either a Discrete TPM (Physical chip) or Firmware-based TPM.

As per THIS article, fTPM is acknowledged by the Trusted Computing Group (TCG) as a perfectly valid form of TPM and seems to perform much the same functions as a physical TPM. For Intel, their fTPM is called Intel Platform Trust Technology (PTT). I don't know what chips/motherboards/BIOS support PTT, however due to it being Firmware based (as the name suggests) and not requiring a separate physical chip, it means for some devices it's possible to retrospectively add a TPM to devices that didn't have one before.

Looking through the Intel NUC list, it's not just 6th gen Skylake NUC's that it's supported on, but also 5th gen Broadwell NUC's and 4th gen Haswell NUC's too. So if you have a NUC and you have the latest BIOS, then the chances are you have a TPM 2.0 module even if you didn't think you did. You just need to enable 'Intel Platform Trust Technology' in BIOS. As previously mentioned, I don't know what other manufacturers support/will support fTPM too.


The Intel Platform Trust Technology (PTT) setting in Intel VisualBIOS:





With Intel PTT on in BIOS, Device Manager and tpm.msc show a TPM 2.0 module installed.

Maybe an addition, unless you have it somewhere else for the Windows Defender Security Center
