Hi:

Yes, you can.

See this discussion:  Your notebook is on the list of those that can support such an update.

Solved: How to update tpm from 1.2 to 2.0 - HP Support Community - 9205712

And how can I upgrade it

[Paul_Tikkanen]

You read and follow the instructions on that attachment I posted in that discussion because HP removed the link to the instruction file.

I also posted the links to the exe file you need to do the TPM update with in that discussion (sp81900).

Hi where can I find the TPM FW BIN file and the appropriate HP TPM Configuration Utility file

[Paul_Tikkanen]

Hi:

They are in that sp81900 exe file link.

I've used the same information myself to update the TPM 1.2 security chip to 2.0 on my HP Elitedesk 800 G3 desktop mini PC.

I read the instructions and did it just for fun.

Why do you want to upgrade the TPM?

If it is to install W11, even if you upgrade to 2.0, none of the processors in the Elitebook 840 G3 meet Microsoft's W11 minimum processor requirements and there are no motherboards with W11 processors you can upgrade to.

You don't need to update the TPM to 2.0 to run W11 or even have a supported processor.

I'm running W11 just fine on my 800 G3 DM which is running with an unsupported Intel i5-6500T processor.

You need an Intel 8th generation core processor to fully meet the W11 processor requirements.

I see this

You need to read the instructions on that word document I attached in that other discussion.

Inside that firmware folder are all of the available firmware files.

You have to select the right one that matches the criteria for your notebook.

IMPORTANT! Before attempting to upgrade to TPM 2.0, make sure the system BIOS has been updated to the latest available
version. Check for the latest BIOS version starting here: http://www.hp.com/drivers.

Instructions
1. Run softpaq to extract files. By default it will extract the files in C:\SWSETUP\SP81900 folder.
2. Copy the desired TPM FW BIN file and the appropriate HP TPM Configuration Utility (either 32-bit or 64-bit) to a
temporary folder. Only one TPM FW BIN file is allowed in the temporary folder.
3. Do not rename the TPM FW BIN file.
4. Open CMD Prompt in Administrator mode and run TPM.MSC to determine the TPM Manufacturer Information.
- Manufacturer Name: IFX
- For TPM 1.2, check the Manufacturer Version 6.40 or 6.41:
- For version 6.40, use file TPM12_6.40.190.0_to_TPM12_6.43.243.0.BIN
- For version 6.41, include logic that tries one and,if it fails, uses the other of these:
TPM12_6.41.197.0_to_TPM12_6.43.243.0.BIN
or
TPM12_6.41.198.0_to_TPM12_6.43.243.0.BIN
NOTE: This is necessary because TPM.msc does not reveal the actual build; no way to tell if you currently have
6.41.197 or 6.41.198.
