TPM issue after BIOS update – Windows 11

[lucaszahdn]

Hello HP Support Team,

I am requesting a technical investigation and, if necessary, a BIOS patch or firmware fix for my HP OMEN 25L Gaming Desktop. I want to explain the full situation so that the underlying issue can be investigated rather than receiving generic troubleshooting instructions.

My system specifications:

• Product: HP OMEN 25L Gaming Desktop GT15-0xxx

• Product SKU: 575M3AA#ABA

• Processor: AMD Ryzen 7 5700G

• Motherboard/Baseboard ID: 89EB

• Operating System: Windows 11 Home 64-bit

• Previous BIOS version: AMI F.20, dated March 15, 2023

• Updated BIOS version: F.39 Rev.A, released May 4, 2026

• Boot mode: UEFI

• Secure Boot: Enabled

What happened:

Before updating my BIOS, my TPM 2.0 was working correctly and Windows reported that the TPM was ready. Secure Boot was enabled, and device encryption was enabled, although I temporarily suspended device encryption during troubleshooting.

My main concern was that Call of Duty was reporting the message "Attestation Required." I wanted to resolve this problem while keeping my computer's security features working correctly.

I investigated the issue and considered whether a BIOS or firmware update could help. I subsequently downloaded and installed HP's official BIOS update, F.39 Rev.A (SP172754.exe).

The BIOS update completed successfully, and my computer restarted normally. I did not experience a failed BIOS flash.

However, I am concerned about TPM 2.0 initialization, detection, and attestation compatibility following the BIOS update. When checking the BIOS Security menu, I saw that the TPM Device setting was set to Available. I want to ensure that the TPM remains properly initialized and that Windows 11 and Call of Duty can use the required security and attestation functionality.

What I am requesting from HP:

1. Please investigate whether BIOS F.39 Rev.A has any TPM 2.0 initialization, firmware, or attestation compatibility issues on the HP OMEN 25L GT15 platform with motherboard ID 89EB and the AMD Ryzen 7 5700G processor.

2. Please confirm whether this BIOS version correctly supports TPM 2.0, Secure Boot, and the attestation functionality required by Windows 11 and Call of Duty.

3. If there is a BIOS firmware defect or compatibility issue, please provide a corrected BIOS update, patch, or official workaround for this exact hardware configuration.

4. Please provide clear instructions for verifying and restoring the correct TPM configuration without unnecessarily clearing the TPM, reinstalling Windows, losing access to encrypted data, or compromising my system's security.

I am looking for a permanent, technically appropriate solution rather than being advised to reinstall Windows or reset security settings without first identifying the underlying cause.

I would greatly appreciate this issue being reviewed by the appropriate BIOS or firmware engineering team. If this requires a new BIOS release, please consider investigating and providing a fix for affected systems.

Thank you for your time and assistance.       Lucas and Chat GPT 😊

Hi @lucaszahdn 
 
Welcome to the HP Support Community!

Thanks for reaching out!

I understand your concern,and I appreciate the thorough troubleshooting you have already performed and your focus on identifying the root cause rather than applying unnecessary resets or reinstallations.

Based on the information you have shared, the issue may be related to TPM attestation behavior on AMD platforms. AMD has published guidance regarding TPM attestation failures on systems utilizing AMD ASP fTPM. I recommend reviewing TPM Attestation Failure on AMD Platforms with ASP fTPM for additional technical details. - Click here

To help ensure the TPM firmware and platform security components are operating correctly, please follow the steps below:

1. Visit the Official HP Drivers and Software Download page.  - Click here 
2. Enter your product name, serial number, or product number.
3. Select Software & Drivers.
4. Choose your operating system and version.
5. Expand BIOS - Firmware.
6. Download and install the latest BIOS version available for your system.
7. Follow the on-screen instructions to complete the BIOS update.
8. After the BIOS flash process completes and the system restarts, follow any TPM initialization prompts that may appear.

Please note that during TPM reinitialization, Windows security credentials may need to be refreshed. Before making any TPM-related changes, ensure you have access to your BitLocker recovery information.

I hope this helps.

Thank you for your response. However, I have already installed BIOS F.39 Rev.A on my HP OMEN 25L Gaming Desktop GT15-0xxx with the HP 89EB motherboard and AMD Ryzen 7 5700G processor.

Before installing F.39, my TPM 2.0 was working correctly. After the update, Windows stopped detecting the TPM. Running Get-Tpm in an administrator PowerShell window reports TpmPresent: False.

Additionally, every time I start my computer, I receive an F1 TPM deletion / F2 continue prompt, which is preventing me from accessing the BIOS normally.

I have not intentionally cleared the TPM, and I want to avoid unnecessary resets or reinstallations that could put my encrypted data at risk.

Since I have already installed the BIOS version recommended by HP, could you please investigate whether F.39 has a known TPM detection issue on this motherboard and advise whether a firmware fix or supported BIOS recovery/downgrade procedure is available?

I would appreciate a solution specific to this issue rather than being advised to repeat the same BIOS update.

Thank you.
