TPM Not Usable, PCR7 Binding Not Possible, and BIOS Update Issues on HP Pavilion Gaming Laptop

[amjaths]

Hello,

I am facing serious security and encryption issues on my laptop. Here are the details:

• TPM 2.0 is enabled in BIOS but reports "TPM not usable" in Windows.

• PCR7 Binding shows "Binding Not Possible" in msinfo32.

• Device Encryption Support fails due to TPM and PCR7 issues.

• Virtualization-based security is active but Hyper-V is off.

• After disabling virtualization in BIOS, hypervisor errors are gone but device encryption still fails.

• BIOS update attempts fail with "Can't open BIOS image file" and earlier reported disk space issues despite sufficient free disk space.

• EFI partition only shows drivers folder; no visible BIOS update files.

• Tried clearing TPM, resetting BIOS to defaults, updating chipset drivers, and running updates as admin.

I suspect these issues are related to firmware or BIOS compatibility with TPM and BitLocker requirements.

Could someone please advise:

1. How to resolve TPM not usable and PCR7 binding issues?

2. How to safely update BIOS and manage EFI space for update?

@amjaths,

Welcome to our HP Community forum!

Thank you for providing the detailed information. Based on the issues you've described with your HP Pavilion 15.6-inch Gaming Laptop PC 15-ec2000 (2P6B2AV), here's a structured approach to resolve the TPM and BitLocker-related problems:

---

1. Resolve TPM Not Usable and PCR7 Binding Issues:

a. Clear TPM in BIOS:

• Restart your laptop and press Esc or F10 during startup to enter the BIOS setup.

• Navigate to the Security tab.

• Select Clear TPM and confirm the action.

• After clearing, save and exit the BIOS.

b. Enable TPM in BIOS:

• Re-enter the BIOS setup.

• Go to the Security tab.

• Ensure that TPM Device is set to Enabled.

• Save and exit the BIOS.

c. Check TPM Status in Windows:

• Press Win + R, type tpm.msc, and press Enter.

• Verify that the TPM is listed as Ready for use.

d. Update TPM Driver:

• Open Device Manager (press Win + X and select Device Manager).

• Expand the Security devices section.

• Right-click on Trusted Platform Module and select Update driver.

• Choose Search automatically for updated driver software.

---

2. Address PCR7 Binding Not Possible:

a. Verify Secure Boot Status:

• Enter the BIOS setup again.

• Navigate to the System Configuration tab.

• Ensure that Secure Boot is set to Enabled.

• Save and exit the BIOS.

b. Check Device Encryption:

• In Windows, go to Settings > Update & Security > Device encryption.

• Ensure that device encryption is turned On.

c. Run System File Checker:

• Open Command Prompt as Administrator (right-click on Start and select Command Prompt (Admin)).

• Type and Enter (or copy/paste/Enter): sfc /scannow

• Wait for the scan to complete, may be a while.

• Copy/paste/Enter: DISM /Online /Cleanup-Image /RestoreHealth
• Wait for the DISM command to complete, may also take (quite) a while.  Be patient.

---

3. Safely Update BIOS and Manage EFI Partition:

a. Prepare for BIOS Update:

• Ensure your laptop is plugged into a power source.

• Download the latest BIOS update for your model from here: https://support.hp.com/in-en/drivers/hp-pavilion-15.6-inch-gaming-laptop-pc-15-ec2000/2100188522.

• Save the BIOS update file to your desktop.

b. Create a Bootable USB Drive:

• Insert a USB flash drive into your laptop.

• Format the USB drive to FAT32.

• Copy the downloaded BIOS update file to the root directory of the USB drive.

c. Update BIOS:

• Restart your laptop and press Esc or F9 during startup to enter the boot menu.

• Select the USB drive as the boot device.

• Follow the on-screen instructions to update the BIOS.

d. Manage EFI Partition:

• After the BIOS update, check the EFI partition:

  • Press Win + X and select Disk Management.

  • Locate the EFI partition (usually labeled as EFI System Partition).

  • Ensure it has sufficient free space (at least 1 GB).

  • If necessary, extend the partition by right-clicking on it and selecting Extend Volume.

---

Additional Tips:

• Check for Windows Updates: Ensure that your Windows operating system is up to date by going to Settings > Update & Security > Windows Update.

• Disable Hyper-V: If you encounter issues with virtualization, you can disable Hyper-V by running (copy/paste/Enter) the following command in an elevated (as Administrator) Command Prompt:

  dism.exe /Online /Disable-Feature:Microsoft-Hyper-V-All

• Consult HP Support: If the issues persist, consider reaching out to HP India Support for further assistance.

Hope this was helpful.

@amjaths,

And lest I forgot to mention it, out of an abundance of caution:

Important Warning Before Proceeding:

Before attempting any of the steps as outlined in my previous post:

1. Back up all your important data -documents, photos, and any files stored on the system drive.

2. If BitLocker is enabled, save your BitLocker recovery key in a safe location (Microsoft account, USB drive, or printed copy).

3. Ensure your laptop is connected to power during BIOS updates to avoid interruptions.

4. Understand that clearing TPM or incorrectly updating BIOS can render Windows unbootable or cause data loss if steps are not followed carefully.

Do not proceed without a complete backup.

Kind Regards,

Thank you for the suggestions. I have cleared the TPM from BIOS as instructed, but TPM still cannot be found in tpm.msc. In Device Manager under Security Devices, I only see "AMD PSP 10.0" listed, not a traditional TPM device. Additionally, in Security Processor details, it shows that TPM 2.0 is not available.

For reference, my BIOS version is AMI F.30, dated 4/23/2025.

Could this AMD PSP device be the firmware TPM ? And is this a known compatibility issue with Windows recognizing TPM 2.0 on this model?

Please advise on any further steps to resolve TPM detection or enable full TPM 2.0 support.

Thank you!

Exact same issue man please reach out if u find solution, I think the problem is with pavilion series

@amjaths,

Sorry for the delayed response -I don't always get notified when OPs such as yourself respond, making it look like there was no activity.

In any regards, it appears that you've already performed all of the appropriate TPM recovery and configuration steps -clearing the TPM in BIOS, confirming fTPM is enabled, reinstalling the AMD PSP driver, and even running the system on the latest BIOS F.30 Rev.A (April 2025). Given that TPM 2.0 still doesn't appear in tpm.msc and that Device Manager → Security Devices only lists "AMD PSP 10.0", what you're seeing is most likely a firmware-level issue in the current BIOS release for certain HP Pavilion 15-ec2000 models.

 

Technical background:

• On AMD-based HP systems, TPM 2.0 is implemented through the AMD Platform Security Processor (PSP) as firmware TPM (fTPM).

• When Windows fails to enumerate fTPM correctly -even though "AMD PSP 10.0" appears, it means the BIOS/firmware isn't exposing the TPM 2.0 interface to Windows Security.

• Multiple Pavilion 15-ec2000 owners (on BIOS F.30 Rev.A) have now reported identical symptoms, suggesting a firmware regression or compatibility fault rather than user configuration error.

 

Recommended actions:

1. Do not attempt further TPM clears -repeated resets can invalidate existing BitLocker or Secure Boot keys without restoring detection.

2. Re-install the latest AMD chipset and PSP driver package directly from AMD’s support site: Drivers and Support for Processors and Graphics.
   (Chipset → AMD 400/500 Series → Ryzen 4000/5000 Mobile).
   Reboot and re-check tpm.msc.

3. Confirm Secure Boot is still Enabled in BIOS.

4. Report the issue to HP Support India so it's logged as a potential BIOS defect for the Pavilion 15-ec2000 series running BIOS F.30 Rev.A.

   • Include: product ID (2P6B2AV), BIOS version (F.30 Rev.A 4/23/2025), and that tpm.msc reports "TPM not found".

   • HP may release a corrected BIOS (F.31 or later) restoring proper fTPM enumeration.

Look, it appears to me that until HP issues an updated BIOS, the fTPM may remain unavailable in Windows Security, meaning Device Encryption and BitLocker can't be enabled. All other system functions, including Secure Boot, will continue to operate normally.
