TPM issue

ali2312 · ‎11-10-2026

My HP OMEN 40L Gaming Desktop (product number 8R3T1AA, motherboard 8A98, BIOS AMI F.20) is failing TPM key attestation.

My AMD TPM firmware version is 6.32.0.6.

TPM 2.0 and Secure Boot are enabled and functioning. However:

* Get-Tpm reports ReadyForAttestation: False.
* IsCapableForAttestation: False.
* Get-TpmEndorsementKeyInfo reports ManufacturerCertificates: {}.
* AIK enrollment fails with error 0x80070490.
* Get-TpmSupportedFeature -FeatureList “Key Attestation” fails with HRESULT 0x80280084.

Please investigate whether there is an updated AMD fTPM firmware, EK certificate provisioning issue, or BIOS compatibility problem for motherboard 8A98.
