Precision 5510 - No TPM option available in BIOS

This question is not answered


I have a Precision 5510 which is Bitlocker/MBAM encrypted but for the past couple of days i've been getting the Recovery screen at each reboot.  After disablin the protector & trying to re-enable it, I get told that 'Compatible TPM cannot be found'.  I know there is a TPM on this as it has already been encrypted so what has happened??  I'm running Windows 10 (x64) & machine is fully patched & using the latest BIOS version (as of today, 26/1/2017).

I did have to perform a hard reboot earlier this week, could this be related?  I did see something online regarding hared reboot affecting Precision 5510 but the solution to reboot did not work for me.  I have also tried to reinstall the TPM driver but it won't appear in Device Manager nor is there an option in BIOS anymore to enable/activate TPM.

I'm at a loss, anyone know if there is a known issue with Precision 5510 losing TPM?

  • Have the same issue today with one of our users.

  • Call support ... they replaced my mainbord... kr Kristof

  • This helped for me:

    1. Power off the laptop and remove any power adapters.
    2. Remove the rear cover (screws do not come out fully).
    3. Remove the SODIMM(s).
    4. Remove the M.2 drive
    5. Remove the battery (one screw, pull the tab to remove the battery connector from the board).
    6. Press and hold the power button for 20 seconds (to drain capacitors).
    7. Reinstall the SODIMM(s).
    8. Put the M.2 drive back in.
    9. Reconnect the battery and screw it down.
    10. Attach the rear cover.
    11. Power on the laptop

     After this TPM was available again in the BIOS.

    Then I updated the TPM from 1.2 to 2.0. You can download the tool when you search for security drivers for Precision 5520 (Note: Dell doesn't provide it on the driver page for 5510, but it can be used for all Dell TPMs that support 2.0). There is also a quite good manual how to install it when using bitlocker (disable bitlocker, Disable Auto Provisioning, Clear TPM, etc.)
