  1. Trying to enable BitLocker but unable to locate Trusted Platform Module TPM


    Hi All,


    I've been dealing with a user's machine Dell Latitude 7480 and I am unable to turn on his BitLocker Encryption. I've done a ton of research and advised him to go to the BIOS Setup on boot up to ensure under Security "TPM 2.0 Security" was turned on but there is no option for this.


    Also, he is getting a pop up message displaying the words "BitLocker cannot be enabled". I sent him the following link to follow - https://helpdeskgeek.com/help-desk/fix-device-cant-use-trusted-platform-module-enabling-bitlocker/


    Now when he turns on his BitLocker it is now asking him two different options from the BitLocker Drive Encryption - Choose how to unlock your drive at startup.


    1. Insert a USB Flash Drive

    2. Enter a password


    He said he chose "enter a password" and when he would shutdown/reboot he had to enter a 30 digit password every time. I just need the user to be able to turn on his BitLocker Encryption for his hard drive but this is proving to be difficult.


    Another thing is I've asked him to type in "tpm.msc" on his machine to see whether it was possible to clear his TPM. The option is greyed out and no cannot be found.


    Any suggestions what I should try next?

    :)

    Bitlocker and Trusted Platform Module problems

    We appreciate the screenshot you sent.

    This issue usually occurs because the Trusted Platform Module (TPM)
    uses the manufacturer driver and not the Windows built-in Trusted Platform Module driver.

    To resolve this, you can manually uninstall and reinstall Trusted Platform Module. To do so, see the steps below:

    • Open Device Manager on the device on which you are experiencing the issue
    • Uninstall the Trusted Platform Module driver.

    Give us an update after following the troubleshooting steps provided.

    Error: This device cannot use a Trusted Platform Module, when enabling Bitlocker

    Hi,



    Thank you for writing to Microsoft Community Forums.



    I understand that you receive an error when enabling Bitlocker on your computer.



    Ideally, Bitlocker requires a compatible TPM (Trusted Platform Module) on the computer to store the encryption keys. The TPM helps in unlocking the drive when the computer boots so that you can sign in to the computer just using the Windows login password.



    However, if you are doing this on your personal computer, we can try to use Bitlocker without a TPM by changing certain Group Policy settings.



    Refer the steps mentioned below:



    1. Press Windows Logo key + R, to open
      Run dialog box.
    2. Navigate to Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives.
    3. Now, on the right pane, double click on Require additional authentication at startup.
    4. Select Enabled and ensure that the checkbox for
      Allow BitLocker without a compatible TPM (requires a password or a startup key on a USB flash drive)
      is selected.
    5. Click on OK to save the settings.
    6. Restart the computer and try enabling Bitlocker.


    If the issue persists, we do have a dedicated forum for issues concerning to Bitlocker and Group Policy, let me point you in the right direction, where you may get further assistance, if the issue persists. I would suggest you to post your query in
    TechNet forums, where we have support
    professionals to address your query.

    Yeah, I misunderstood you, I was thinking TPM. Anyway I just checked my BIOS and interestingly enough, mine is disabled, and yet no issues with my TPM module or BitLocker here....

    All that said, it probably wouldn't hurt if the OP doubled checked the BIOS and tried enabling PTT to see what happens.

    And yes, Secure Boot is Enabled, along with Key Management.
