TPM update on a precision T5810 issue

Download and run this TPM 2.0 Firmware Update Utility.  It fixed the issue where TPM option does not show up under Windows with previous TPM firmware.  Scroll down on that page for installation instructions.

https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=rf87d&oscode=wt64a&productcode=precision-t5810-workstation

with this file, it indicate  “Error: The System TPM Query Failled, Aborting” and “Error: Unable to prepare the TPM update payload.”

I run the file with admin rights. the TPM is enable in the bios

I don't know how to unlock the TPM.

hi,

after a reset with jumpers RTCRST and PSWD and bios defautlt and reactivate TPM,

now it's works

PS C:\Windows\system32> get-tpm

Can I update to 2.0

finally with DellTpm1.2_Fw5.81.2.1_V3_64.exe, I can update to TMP 2.0 and TMP2.0 is seen by windows

I had the same issue after running the TPM 2.0 update utility (DellTpm2.0_Fw1.3.2.8_V3_64.exe)

Initially downgraded the BIOS from A34 to A16

Upgraded back to A34

Powered down the system

Move the PSWD jumper to RTCRST for 10 seconds

Powered the system back up into BIOS setup

Loaded defaults and changed the required settings back on in my case for the HDD from RAID to ATA

Turned TPM2.0 on and enabled

Saved and exited

Rebooted and all okay TPM2.0 showing in device manager.

Jumper 22 PSWD - Jumper 28 RTCRST
