Missing TPM after formatting my HP computer

[Ezra989]

I used Windows 11 until Monday when I formatted my laptop HP ProBook 450 G8 Notebook, but now I can't find TPM. TPM is present on the device manager and no TPM in the security section of bios. The bios is up to date. Health check; TPM not detected. What could be the problem?

Does HP consider this a manufacturing defect? I have three HP laptops, and two are working okay. Only the HP ProBook 450 G8 Notebook PC (281U3PC) has a TPM issue. 

1. TPM is not on BIOS. 

2. TPM is present on Device Manager

3 BIOS is up to date. 

Secure boot is on.

Hello,

Welcome !

Could you elaborate ? Is it  or  is it not in the Windows Device Manager ? How about opening tpm.msc  from the Windows search ? What's the status there ?

1. Please, hard reset / power reset your notebook by pressing and holding your power-on button for 15 seconds. Then repeat the procedure by pressing and holding your power-on button for 30 seconds. Here are instructions >> https://support.hp.com/sg-en/document/ish_1997208-1551050-16

2. Confirm you are really on 01.19 BIOS version >> https://ftp.hp.com/pub/softpaq/sp156001-156500/sp156025.exe

3. Go to BIOS F10 -> Security tab ? Do you see TPM options there ?

While in the Security tab, could you press the "Restore Security settings to Default" button. Exit the BIOS and follow the on-screen instructions.  After rebooting the PC, do you notice the TPM module in BIOS and/or Windows ?

Thank you.

I have followed the steps but there was no solution. Yes, TPM is present on the device manager. There is no TPM when I search using tpm.msc. There is no TPM on bios. Bios is T70 ver.01.19.00.

Hello @Ezra989 

Thank you for following the steps and for the prompt response.

Has anything changed in your "environment" recently ? Has the computer been repaired, any parts changed ?

Can you go to BIOS, choose F1 option (System Information) and take a picture / post it back here ?

Cheers,

The warranty expired 5 days ago, there was no repair done. I formatted the computer and installed a new OS. Attached is the  requested screenshot
