Latitude 5480 TPM Device Not Detected Error

Hi,

We are having issues with several 5480 laptops giving the error "Alert! TPM device is not detected" on start up.

This has started on all these laptops after updating the bios to the latest version. 

We have tried many troubleshooting techniques but nothing shows in the bios settings to disable/enable it, TPM cant be found with in the windows utility and PowerShell says "The Device Is Not Ready" when running any TPM related command

If anyone has a fix for this or Dell can fix this issue in the next BIOS update that would be appreciated. 

Many Thanks

This support page may help. Dell is also in the process of issuing firmware for TPM 1.2 to 2.0. This coincides with the Windows 11 launch. Your 5480 systems may be on the edge of the possible upgrade as I believe you have generation 7 CPUs and MS looks to be changing the system requirement from generation 8 to 7. This page may be of interest as well.

Thanks for your reply JOcean,

We have tried the troubleshooting tips in that 1st support page and none of them worked

We have also tried downloading TPM 1.2 and 2.0 firmware from the Website but both give and error when installing. The 1st error is "Error: The System TPM Query Failed, Aborting" and the 2nd is "Error: Unable to prepare the TPM update payload."

Many Thanks

Just a guess but seeing that you have Intel CPUs, is PTT enabled in the BIOS?

There is no option to enable or disable PTT in the BIOS

Are the systems in UEFI or Legacy boot mode? I have to assume they are UEFI. More information, I have loads of that, can be found here.

yes they are is UEFI boot mode.

I've attached some images that should help explain the situation more

 

TPM ERROR.jpgThe Error we are getting in the 1st place

TPM BIOS NO-min.jpgThis is the bios options we can see, there are no options under security for TPM or PTT

TPM PROGRAM ERROR-min.jpgError within the windows utility

TPM POWERSHELL-min.jpgPowershell showing TPM as false

TPM INSTALL ERROR 1-min.jpgThis is the 1st error when trying to install TPM 2.0 or 1.2

TPM INSTALL ERROR 2-min.jpgand this is the 2nd error when trying to install TPM 2.0 or 1.2

Hopefully this helps demonstrate the issues here a bit more

Hello Ashley,

same prob shows up here after the BIOS update.
We solved the prob with downgrade to BIOS 1.17.1
At 1.17.1 we disabled TPM in BIOS, updated to latest BIOS 1.20.2
and enabled TPM again after the BIOS update.

Did you manage to fix this issue. We've got the same issue on a Dell Latitude 5480
