Not this machine, but another (Lenovo X1-Carbon laptop) still running Windows-10 Pro ...
In (a UEFI-class) BIOS-Setup: Switching away from TPM-1.2 ... you enable Intel-PTT/TPM-2.0 .
From my notes:
- Config/Intel-AMT/Disabled (only select this Temporary way. Not usable with Intel-PTT anyway) - Security/Security Chip/Security Chip Selection/Intel-PTT (TPM-2.0) - Security/Security Chip/Intel-TXT Feature/Disabled (not available with Intel-PTT/TPM-2.0) - Security/Secure Boot/Enabled - Startup/UEFI Only Note: Google-AI says Intel-ATM and Intel-TXT ARE NOT for "Casual Home Users"
Windows-11 Health Checkup now says TPM-2.0 is fine.
@Tesla1856 Dell has a list of PC's that have PTT. The 5820 is one of them and like I said, we've upgraded TPM several times. Accessing Native Intel PTT is an interesting challenge. I found discussion on it in our Intel Internals documentation....from 2022, when it was fairly new. My Partner suggested changing the BIOS Battery, we've seen that cause weird issues, but, No Joy. I think my weekend will be studying Intel PTT Internals. Thanks for the nudge in that direction.
Good, hope that helps. I just got that machine out of the closet and was messing with those options.
On that laptop ... read those BIOS options above ... Intel-PTT *IS* TPM-2.0 .
And basically, if you want to Enable it, you have to make sure those others are OFF. They are for using advanced network management features on some corporate networks (I think usually with fairly elaborate Windows Servers controlling things).
I went down the PTT Rabit Hole last night. It's good to review stuff like this. PTT is processor based and the machine I'm working on is a Xeon T5820 Workstation, no PTT. It is supposed to have Nuvoton TPM, which I think is integrated into the BIOS chip. I have another T5820 that has the same processor, same MB, same amount of RAM, it's almost the same except for the drive. I was successful upgrading that one a couple weeks ago, but not the other one, rather, the other two in this case. This does not give me a PTT error, so it must be Nuvoton. The DellTpm2.0_Fw1.3.2.8_V3_64.exe update application. I also tried DellTpm2.0_Fw1.3.2.8_V1_64.exe. I never found a version 2. I think the key is the Upgrade Failed statement: Blocked by TPM FW Policy....

1. Good info.
3. Maybe you can find a better Nuvoton TPM updater
@Tesla1856 Very Good Suggestion Tesla1856! Thank you for being interested. Unfortunately, that is an update to TPM 2.0, not the upgrade from 1.2 to 2.0.
Saturday, I had a machine that was updated and one of the two troublesome machines, side by side. The only difference in the Motherboards was the serial number... I took the heat sinks off the BIOS chips, cleaned off the thermal paste and they are the same. I was certain they would be different. There's something in BIOS on these two machines that is blocking the upgrade. I've tried resetting the BIOS by the pin and by pulling the battery. I'm leaning toward the Intel management function in BIOS. I probably have documentation on that somewhere, I just have to look. I'll keep you informed.
I've learned a lot about DELL TPM, more than I expected I, or anyone needs. This applies to the Dell Precision T5820, but might apply to other Dell machines. There are several types of programmable TPM, the one I'm working with is Nuvoton. Dell has a BUNCH of firmware updates that work on this, Each one is a bit different. Dell has two TPM firmware updates that work in DOS and 4 for Windows. The DOS ones are: DellTpm2.0__Fw1.3.2.8_v1_64 & DellTpm2.0__Fw1.3.2.8_v3_64, I could not find a version 2. There are 4 versions to update TPM for Windows: DELLTPM_NPCT750_7.2.2.0_64_v1, DELLTPM_NPCT750_7.2.2.0_64_v2, DELLTPM_NPCT750_7.2.2.0_64_v3, DELLTPM_NPCT750_7.2.2.0_64_v4. Each of those upgrade TPM from 1.2 to 2.0. They are NOT upgrade to existing TPM 2.0 like several people have stated. The latest TPM for this machine is version 7.2.2.0.
Partially Solved my issue. Before I go on, a little background. I have a drive with a fresh install of Windows 10 Pro on it, I have a drive with a fresh install of Windows 11 Pro on it and I have a DOS boot disk. The DOS only works with The DellTpm2.0__Fw1.3.2.8_v1_64. The DELLTPM_NPCT750_7.2.2.0_64_v1 file on both Windows 10 & 11 gets past the "Update Blocked by FW Policy", but fails with the error: "Update Failed: Invalid Command tag/ordinal". In researching this, it suggested to make sure the TPM is totally clear. I cleared it from the TPM.MSC command as well as went into BIOS and cleared it. When you clear it in BIOS it often disables TPM, so you must go back in, before it boots, and turn it back on. What that means is I've cleared TPM.... and it still fails.
This is where I am right now. More to come, I hope.
I gave up and called Dell. The person asked for the Service Tag and Express License Code. I gave it to him. He said the machine had not been registered, which is why it would not update. I asked if I could register it. He said it is outside of warranty and could not.... I don't know if this is correct, but it is one answer...

Your initial post calls them 5280's ?

@StLAdmin ,
How about version-4 here:
https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=pg1rm&oscode=wt64a&productcode=precision-5820-workstation
DELLTPM_NPCT750_7.2.2.0_64_v4.exe
Remember to always "unBlock" these files in File-Explorer before running them.

@Tesla1856 the PC is a Dell Precision T5820, my mistake. I type fast and don't always proof read.

@StLAdmin ,
Sounds more like a way to get you off the phone.
