Hi @Ayush_05,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand the TPM option has disappeared from the BIOS and it's not showing up in Windows 11, there could be a few reasons for this issue. 

Here are some steps to troubleshoot and potentially resolve the problem:

1. Check BIOS Settings

Even though you've updated the BIOS, it's worth double-checking the BIOS settings:

• Reboot your laptop and enter the BIOS setup (usually by pressing F10 during startup).
• Navigate to the Security tab and look for TPM settings. Ensure it's enabled.
• If you don't see TPM settings, look for any option related to "Security Device Support" and ensure it’s enabled.

2. Load BIOS Defaults

Sometimes, loading the BIOS defaults can help in re-detecting the TPM:

• Enter the BIOS setup.
• Look for an option to load BIOS defaults, which is usually under the "Exit" menu or a specific option like "Load Setup Defaults."
• Save and exit the BIOS.

3. Check for Firmware TPM (fTPM) vs. Discrete TPM

Some laptops have both discrete TPM and firmware-based TPM (fTPM):

• Look for options related to fTPM or PTT (Platform Trust Technology) in the BIOS.
• Ensure any related settings are enabled.

4. Windows TPM Management

Check the status of TPM in Windows:

• Press Win + R, type tpm.msc, and press Enter.
• If TPM is detected, it will show the TPM Management Console. If not, it will say "Compatible TPM cannot be found."

5. Device Manager

Ensure TPM is not hidden in Device Manager:

• Open Device Manager.
• Click on "View" and select "Show hidden devices."
• Expand "Security devices" and check if TPM is listed. If not, look for any devices with yellow exclamation marks, indicating driver issues.

6. Windows Update

Ensure Windows is fully updated:

• Go to Settings > Update & Security > Windows Update and check for updates.
• Sometimes, driver updates for TPM are distributed through Windows Update.

7. Reinstall TPM Driver

Try reinstalling the TPM driver manually:

• Visit the HP Support website and download the TPM driver for your model.
• Install the driver and reboot the laptop.

8. BIOS Update or Downgrade

Since updating the BIOS didn't resolve the issue, consider the following:

• Check HP's website to see if there is any specific BIOS version that addresses TPM issues.
• As a last resort, consider downgrading the BIOS to a previous version where TPM was functional.

I hope this helps. 

Take care and have a good day.
