TMP Issue

Hello,

 We have a Poweredge T30. Someone decided to mess with the TPM. It looks like when trying to update the TPM from 1.2 to 2.0 the flash never completed due to the system loosing power. 

In BIOS TPM 1.2 shows up and can be enabled or disabled.

In device manager TPM does not show up under "Security Devices" or "System Devices" - We do have the option to add the TPM 2.0 under "Add Legacy Hardware"

Even if TPM is reinstalled using the "add legacy hardware" option, and with TPM enabled in BIOS, tpm.msc Still shows "Compatible TPM cannot be found" 

If trying to use the 1.2 or the 2.0 .exe to re-flash, the following error shows up for TPPM Update Program "Error: The System TPM Query Failed, Aborting"

 

Looking for any help to get the system back to how it was. Either with the 1.2 TPM or updated to the 2.0

 

Thank you

Have you tried any of the suggestions found here at the MUO site?

A Trusted Platform Module (TPM) is a chip that resides inside a computer and is soldered to the system board on Dell computers. A TPM’s primary function is to securely generate cryptographic keys, but it has other functions as well. Each TPM chip has a unique and secret RSA key that is embedded into it on production.

Resetting the TPM is not the same as clearing the TPM. During a TPM reset, the computer attempts to redetect the TPM and preserve the data that is held within. Here are the steps to perform a TPM reset on your Dell computer:

For laptops
Remove the AC adapter, turn off the computer, and disconnect any USB devices.
Turn on the computer and press F2 key to enter BIOS or System Setup.
Is TPM available under Security? If yes, no further steps are required.
If TPM is not present, turn off the computer and disconnect the battery (if the battery is removable).
Discharge static power by pressing and holding the power button for over 60 seconds.
Connect the battery (if the battery is removable), AC adapter, and turn on computer.


For desktops and all-in-ones
Turn off the computer and unplug the power cable from the back of the computer.
Discharge static power by pressing and holding the power button for over 60 seconds.
Connect the power cable to the back of the computer and turn on the computer.

 

Greeting,
