PD 400 G2.5 SFF - Can't find BIOS update

[josetur]

Hello good evening. I need someone's help to update the BIOS of my computer to activate the TPM 2.0 because in my current BIOS, I can't find the option to do it and I really need it. I have an HP Prodesk 400 G2.5 SFF with an Intel I5-4590S processor. But when checking the drivers on the official support page (where the drivers are supposed to be) they are not there, I need to flash a USB with that driver and it is simply as if it does not exist. Would you do me a big favor by finding the BIOS update for me? Thank you and good night.

The latest bios for your system is 2.27 dated Dec 2, 2019

At the 44 second mark in this video the author show how to find if your system supports TPM

if you have tpm 1.2 you can do bitlocker.  Upgrade to 2 will  not make your system qualified for windows 11.

It is not necessary to have tpm 2 for windows 11.  Do you need help upgrading to wijndows 11?

Hi, @josetur 

BIOS updates do not update the TPM firmware to 2.0.

There is separate way to do that on select HP business class PC's and your 400 G2 SFF is not on the list of those supported for the upgrade.

HP Desktops, Notebooks, and Workstations - HP TPM Configuration Utility With Windows 10 Anniversary ...

I'm running W11 on two Dell PC's with Intel 4th generation core processors, and I have found that this video is very easy to use to update from W10>W11 or W11 to newer builds of W11:

If you are interested in installing W11 23H2 on your PC as is, watch this video:

How to install Windows 11 24H2 on Unsupported PC (Early Access) 2024 (youtube.com)

Download the W23H2 ISO file and use that (3rd option).   

Download Windows 11 (microsoft.com)

You'll have to repeat this procedure each October when Microsoft rolls out the new builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

@Paul_Tikkanen there is an updated list at the bottom of this document, but the G2.5 is not listed

I just need to update the TPM 1.2 to 2.0 and I already have Windows 11. I can't find any TPM option in the BIOS that i actually have (2015 update) and that's why i wanted to update the BIOS, to see if I finally find the trusted TPM option. I need the link to download the BIOS update and then with that, getting TPM 2.0 activated. Do you think my PC it is not supported to TPM 2.0 or something like that?

[Paul_Tikkanen · Accepted solution]

Your notebook definitely does not support updating to TPM 2.0.

Only the HP business PC's with Intel 6th generation core or newer processors have TPM 1.2 versions that can be updated to 2.0.

Some Prodesk 400's G2/G2.5's don't even have TPM security devices.  It was an option on those.

Yours is probably one of those if in the BIOS's security section there is no embedded security device to hide or show.

The Embedded security device is the TPM chip.

Oh, that's actually sad, I didn't know that, thank you for letting me know

You're very welcome.

You will need to use that video to upgrade your W11 23H2 installation to 24H2 because none of the other tricks I used to use worked when I tried doing an in-place upgrade from W11 23H2 to 24H2 with my Rufus W11-hardware check bypass flash drive.

My HP 350 G1 notebook (Intel 4th gen core processor) has no TPM chip but like yours has secure boot and a UEFI BIOS.

When I clicked on the W11 24H2 setup information file, it checked my PC like always but this time it rejected upgrading because it indicated my PC had no TPM security device.

The procedure in the video worked perfectly and it also worked on an older PC I have that does not support secure boot.
