But how can that be i updated my OS from Windows 10 to Windows 11 so i should have Tpm enabled alrdy no? So now all of the sudden i cant play games like Valorant or League cause the require tpm2.0.

Hi @Darren38 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

It sounds like you're encountering a frustrating issue with TPM 2.0 on your HP Pavilion 15-ec2000 laptop. Even though TPM is enabled in your BIOS, the system isn't recognizing it properly. 

Let's work through some steps to resolve this:

1. Verify TPM Status

• Press Windows + R, type tpm.msc, and press Enter.
• Check the Status. If it says "The TPM is ready for use," then TPM 2.0 is enabled. If not, proceed to the next steps.

2. Clear TPM

• Restart your laptop and enter the BIOS/UEFI settings by pressing F10 during startup.
• Navigate to the Security tab and look for the TPM settings.
• Select Clear TPM or Reset TPM (this will not erase your data but will reset the TPM configuration).
• Save changes and exit the BIOS.

3. Enable Secure Boot

• In the BIOS, ensure Secure Boot is enabled. This is often required alongside TPM 2.0 for features like device encryption.
• Navigate to the Boot Options or Security tab in the BIOS and enable Secure Boot.
• Save changes and restart your laptop.

4. Update BIOS

• Visit the HP Support website and check for the latest BIOS update for your laptop model.
• Install the update and restart your laptop. BIOS updates often resolve TPM-related issues.

5. Resolve PCR7 Binding and DMA Issues

• PCR7 Binding: This is related to BitLocker and Secure Boot. Ensure Secure Boot is enabled in the BIOS.
• Un-allowed DMA-capable Devices: Disconnect any external devices (e.g., USB drives, docks) and restart your laptop. Some devices can interfere with TPM.

6. Check Windows Settings

• Go to Settings > Privacy & Security > Device Security.
• Under Security Processor, check if the TPM is listed and operational.
• If not, click Security Processor Troubleshooting and follow the prompts.

7. Reinstall Windows

• If the issue persists, consider performing a clean installation of Windows 11. This can resolve software conflicts and corrupted system files.
