Can't Enable TPM in Bios

[HasnatJavaid]

Hello Everyone, 

I am trying to enable TPM in my Elitebook 840 G2. I can't change TPM embedded settings in bios. I tried every thing. My Bios version is 1.31. I don't know where is the problem. I hope TPM 1.2 is installed in my laptop.

The series has TPM 1.2 BUT not all machines of the series have TPM.   Page 116 of the following manual shows you the settings process.

Hi, @HasnatJavaid 

If you are wanting to enable the TPM so you can upgrade to W11, your notebook's processor also does not meet the W11 hardware requirements established by Microsoft.

You can read this discussion for how I upgraded several HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11.

Hi, 

Thanks for your reply. I reset my BIOS settings and changed the password. Now I enabled TPM in BIOS but windows 10 is not recognizing TPM now. Can you help me to resolve the issue. I am attaching the screenshots. I manually tried to manually install through add a new hardware option in device manager. It shows option to install TPM 2.0 I installed it but still my windows couldn't  Recognize it. SO I uninstalled and rebooted my PC. I am using Win10 x64 bit lasted built with all updates

Maybe I will But I can manage to install without TPM or CPU. I used to install it on Both my office and Home Desktops. But I want to enable TPM.

I believe that you need this driver for the keyboard filter device in your screenshot.

This package provides HP Hotkey support for special function keys on supported computer models that are running a supported operating system.

Can't help you with the TPM device not showing up.

I think that is a lost cause.
