After BIOS F.49 update, TPM 2.0 missing on HP Notebook 15-da0077tx

[Roni04]

Hello,

I have an HP Notebook 15-da0077tx with Intel Core i5-8250U.
After updating to BIOS F.49 (20-08-2024, InsydeH2O), the option for Intel PTT / TPM 2.0 has disappeared from BIOS.

• In Windows 11, "tpm.msc" shows: “Compatible TPM cannot be found.”

• In BIOS → Security tab, there is no setting for TPM / PTT.

• Rollback to BIOS F.48 is blocked due to security lock.

• Previously, with BIOS F.48, TPM 2.0 worked fine and I successfully installed Windows 11 Pro 24H2 and also order builds with Secure Boot enabled.

This looks like a BIOS F.49 regression/bug that prevents Windows 11 installation with TPM 2.0.
Please escalate this issue to the BIOS engineering team and provide either:

• A fix in the next BIOS (F.50 or later), or

• A rollback path to F.48 where TPM was working.

Thank you.

Hi @Roni04,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand that after updating your HP Notebook 15-da0077tx to BIOS F.49, the Intel PTT/TPM 2.0 option has disappeared, and Windows now reports “Compatible TPM cannot be found.” Since TPM 2.0 worked fine on BIOS F.48, this does look like a regression in the new BIOS.

Clear CMOS / Restore Defaults

Enter BIOS → press F9 (Load Defaults) → press F10 (Save & Exit).

Restart and check if TPM/Intel PTT reappears.

Check BIOS Security Tab

Sometimes TPM is listed as Intel Platform Trust Technology (PTT). If available, enable it.

Update Chipset Drivers

Install the latest Intel chipset and Management Engine drivers from the HP Support site for your model.

I hope this helps.
