How do I update my TPM from 1.2 to 2?

When a system board is replaced, you must make sure that the TPM 2.0 firmware is updated to the latest version.

To update the TPM version:

1. Go to Lenovo Data Center Support and navigate to the support page for your server.

2. Click Drivers & Software and download the latest version of BIOS/UEFI firmware.

3. Update the firmware. See Firmware updates.

4. Power on the system and press F1.

5. If you have set the power on password, enter the correct password.

6. Wait for about 90 seconds, the setup utilities window is displayed.

7. Navigate to and update the TPM.

8. Reboot the system once the update is complete.

Hi:

Your notebook is not supported for the TPM 1.2 to 2.0 firmware upgrade.

Only the PC's on the list below can have the TPM 1.2 device upgraded to 2.0.

If you are wanting to do this in order to upgrade to W11, your notebook's processor is also not supported.

Needs to be an Intel 8th gen core, and yours is only a 4th gen core.

If you want to install W11 on your PC as is, you can bypass the W11 hardware requirements using two easy methods.  The first one is the easiest.

I would make a system image of your current W10 installation prior to updating to W11, so you can easily reinstall W10 in the future.  I used the free Macrium Reflect software to do that, under the Backup at Home section. 

Along with the system image, make sure you create the bootable DVD or USB rescue drive you boot from to access the system image stored on your portable hard drive.

No registry changes needed.  No need to create installation media.  Just download the W11 ISO file, and the guy's zip file.

I used the first procedure to do an in-place upgrade an old HP Elitebook 6930p notebook made in 2010 to W11, and I was able to keep my old Office 2010 Starter program that came with the notebook when it had W7 on it, along with all of my other programs, files and settings.

The notebook met none of the enhanced W11 hardware requirements.

That is the 9th unsupported W11 PC I have upgraded to W11, and not one of them have had any issues whatsoever.

They have all gotten all the Windows 11 updates released thus far.

I check those against a PC I have that is fully supported to run W11.

There is also this way you can upgrade to W11, bypassing the hardware checks...

If you have a recent business-class Dell PC with TPM version 1.2, you may be able to upgrade it to TPM version 2.0. Several Dell models are capable of switching between TPM version 1.2 and 2.0 provided a few conditions are met.

Prerequisites

First, your PC must support switching to TPM 2.0. Most supported models are listed in the “Compatible Systems” section of the instructions for the Dell TPM 2.0 Firmware Update Utility itself. If you can’t find your system in that list, there’s a good chance it isn’t supported by this process.

Second, your PC should be configured in UEFI Boot Mode instead of Legacy Boot Mode. Switching boot modes generally requires a reinstallation of Windows, so it’s best to choose UEFI from the start.

Finally, while optional, it’s recommended that you update your BIOS to the latest version. You can get your serial number by running wmic bios get serialnumber from within PowerShell or Command Prompt. Then, you can provide this serial number to the Dell support website to find the latest drivers and downloads for your PC.

Once you’re ready, you can clear the TPM and run the firmware update utility. However, since Windows will automatically take ownership of a fresh TPM after a reboot by default, we have to take some additional steps to make sure the TPM stays deprovisioned throughout the upgrade process.

Step-By-Step Instructions

1. First, launch a PowerShell window with administrative privileges. Then, run the following command to disable TPM auto-provisioning (we’ll turn it back on later):

   PS C:\> Disable-TpmAutoProvisioning 

2. Next, reboot, and enter the BIOS settings. Navigate to “Security > TPM 1.2/2.0 Security”. If the TPM is turned off or disabled, enable it. Otherwise, click the “Clear” checkbox and select “Yes” to clear the TPM settings.
3. Then, boot back to Windows, and download the TPM 2.0 Firmware Update Utility. Run the package, which will trigger a reboot similar to a BIOS update.
4. When your PC boots back up, run the following command in another elevated PowerShell window:

   PS C:\> Enable-TpmAutoProvisioning 

5. Reboot your PC again so that Windows can automatically provision the TPM. While you’re rebooting, you can take this opportunity to enter the BIOS and ensure that Secure Boot is enabled (Legacy Option ROMs under “General > Advanced Boot Options” must be disabled first).
6. Finally, check tpm.msc or the Windows Security app to ensure that your TPM is active and provisioned.
