TPM - Attestation Not ready

[MrPowershell]

Hi,

I have a TPM not woring on one computer. Attestation is "Not ready". Clearing TPM did not help. And because of this I can't enable BitLocker on the OS drive.

I upgraded the BIOS with sp84209 from this page https://support.hp.com/us-en/document/c05792935#6efa5aef-e44d-408a-8077-117616953373 That did not work. Not after clearing the TMP either.

I installed HP Support Assistant (that was missing) and upgraded the BIOS and some other stuff. I'm now on BIOS F.48. That did not help.

The windows TPM logs gives some information:

Eventviewer generates a lot of TPM id 15:

"The device driver for the Trusted Platform Module (TPM) encountered a non-recoverable error in the TPM hardware, which prevents TPM services (such as data encryption) from being used. For further help, please contact the computer manufacturer."

From the TpmInformation file:

@MrPowershell Welcome to HP Forums!

I have a few steps to help you out:

Windows Defender can tell you which TPM version the system ships with:

• Open Windows Defender Security Center (double-clicking on the shield icon) and head to Device Safety
• Details for the Safety Management Program.
• Look on Specification-Version.
• Then download the version of the TPM update that corresponds to the spec version to resolve the issue.

Ensure you install the latest driver version of all available drivers on the HP support site for Chipset among others, once installed, restart the device and let me know if it works.

If you wish to thank me for my efforts, you could click on "Accept as solution" on my first post as the solution to help others too.

I will try to locate a TPM 2.0 driver then. But as far as HP Support Assistant is consented only a Intel Graphics driver is missing. And then I first looked at the support web I did not find anything clearly related to TPM. Chipset and BIOS should now be up to date.

Also tried to reset TPM in BIOS.

@MrPowershell I suggest you check that, if it doesn't work, you may need to talk to HP for support, as they may need to use the SMC file to clear the TPM:

follow the below steps to get started:

1) Click on this link - www.hp.com/contacthp/

2) Click on "Continue as guest".

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, is yes? please send me a private message with the region you are contacting us from,
