"TPM failure." during POST on Poweredge T620
Hi all,
During boot up of a PowerEdge T620 (this is a used server that I am repurposing), I see a message: "TPM failure."
In Windows, when I go to tpm.msc, it tells me that there is no TPM found. In the BIOS, I tried a few different settings with the TPM options but it makes no difference. The BIOS does, though, tell me that the TPM is active ??
The prior Windows Server installation on this server didn't use the TPM so I have no idea if the TPM was ever working or if there even in fact is a TPM module in this server that has failed (how would I know if there is one anyway … did all T620's come with a TPM ?).
This server is beyond warranty, and I don't think there's anyway to get a TPM replacement, other than replacing the entire motherboard …. so I may just go with Bitlocker with the USB drive option on startup....

I apologize, that was based on a different system type altogether.
I suggest clearing the NVram and see if the TPM failure message clears out, if not then it will likely require a new motherboard to resolve the error. The jumpers for clearing the NVram can be found next to the coin battery on the motherboard. Poswer down the server and move jumper over, power the server to clear the nvram, power down afterwards and restore jumper to original location. After that then power up and let me know what you see.

Mike-ffec,
You can find failure points, as well as troubleshooting steps for the TPM here. I suggest you start with the following;
Verify that TPM is enabled and activated in the BIOS following the steps below:
Let me know what you see from that, and any other tests you do from the page.

Chris,
The Poweredge T620 bios settings appear to be different than what is shown in the link you had provided (which I think is as seen on regular Dell computers). I don't see an Attestation Enable nor Key Storage Enable setting in the server bios under System Security. BIOS is version 2.8.0 which I had updated after acquiring this server. I didn't check if the TPM worked under the old BIOS version. I'm not sure the BIOS version should make any difference.
It does show TPM status as Enabled, Activated even though I do get TPM failure. during boot (as I showed in my other post). And within a clean install of Windows Server 2019, tpm.msc says there is no TPM present.

Just wanted to get back and let you know that clearing the NVram did the trick!
Seems like when I did the BIOS firmware update, it may have scrambled something there to do with the TPM.
Anyway, it works. The "TPM failure." message went away and that in Windows, tpm.msc reports that there is now a working TPM module.
Thank you!
