Cannot activate TPM module (grayed out)

Hello,

I would like to enable the secure platform module (TPM) in my BIOS, but to my great surprise, the option is greyed out. How can I enable it, please? I have an HP EliteBook 8460p.

      Indeed, it's for Windows 11. I was finally able to activate it by setting a password in the BIOS; the only downside is that I have version 1.2. Is it possible for me to upgrade to 2.0 with my model?

        On mine, it is activated even though I didn't set a password; it's important to know that each BIOS has its peculiarities, which is why there's no one-size-fits-all solution. 
        Is it possible for my model to upgrade to 2.0?

        No, it is not possible; TPM is not the only thing that needs to be enabled or possessed, see my message here https://forums.commentcamarche.net/forum/affich-37260815-ne-peut-active-le-module-tpm-grise#4

    Unless I'm mistaken, TPM and Windows 11 have no direct connection (though it's true that it doesn't say why either).

    We have been using it (in a professional context) for a while on the work HPs.
    In our case, it's "combined" with disk encryption via third-party software and on Win 10 Pro.

    The chipset must already exist on the model in question, and since HP has series of the same model with and without... this may explain why it is greyed out, same BIOS but not the same options?

    If I were you, I would contact HP with the machine's serial number to find out more.

    Best regards

      Hi, I tested Microsoft's Windows 11 compatibility tool and my PC, Dell Inspiron 7586, which is less than 2 years old, is declared not compatible. In my BIOS, there's no trace of TPM security, but I found out there is PTT security (a low-cost version of TPM). I just contacted Dell support to find out if this will be sufficient for Windows 11.

      Afterward, on my PC, I installed a VM using VmWare with the W11 ISO I downloaded a few days ago, and there were no issues, even though the hardware of a VM is generally a simplified or degraded version of the physical host machine.

       that there is a PTT security (low-cost TPM module)

      You need to have an Intel processor, and so that is what needs to be activated.

      Additional information:

      For compatibility with Windows 11:

      - You need to enable TPM in the BIOS; its version must be 2.0. To check if it is activated and its version, simultaneously press the Windows and R keys, a window will appear, copy/paste tpm.msc and then click OK.

      - The graphics card must be DirectX 12 and have a WDDM version 2 driver. To see if it's good for you, in the search field, copy/paste DXdiag. A window will appear, in the System tab, you will find the DirectX version, and in the Display tab, the WDDM version.

      - The "secure boot" must be enabled in the BIOS.

      - The BIOS must be in UEFI.

      I know this is a lot of "needs," but Microsoft is developing a new compatibility tool that will explain the reasons for incompatibility. This is just a first draft; Microsoft will likely lower its requirements, so just wait for the follow-up and don't rush or panic for no reason.

      Remember, before the arrival of W10, it was the same; the first versions left behind all PCs over 2 or 3 years old, but that wasn’t the case.

      Yes, that's why I reached out to Dell support; the manufacturers are the most interested. It would be stupid for a PC that is less than 2 years old not to be able to upgrade to Windows 11, while I have a Dell that is over 15 years old, originally running XP, that has gone through W7, W8, and finally W10.

    The processor must also be compatible; not all are supported, Intel CPUs are only supported from the 8th generation onwards, see the list of supported processors:

        Hi everyone,

        No, it's ongoing!
        It's common practice at Microsoft.
        Copy to be reviewed ==► The editor emphasizes that it "will be back online in preparation for the general availability (Editor's note: of Windows 11?) in the fall."

    maybe we can change the TPM chip on the motherboard.
    For me, the slot was there but empty, yet it's a recent computer, less than 2 years old.
    The challenge now is to find a 2.0 chip on the market and that's a huge desert.
