A new BIOS

[Samlash]

Hello,
I have an HP ProDesk 400 G3 MT. My current BIOS version is 02.47.
I need BIOS version 02.62 Rev.A, which allows upgrading TPM 1.2 to TPM 2.0 for Windows 11 and Valorant.
Unfortunately, it's no longer available on the HP support site or FTP.

Can you please provide me with a secure download link for this BIOS update?

Thank you!

Hi:

If you look at the release notes for all of the previous versions on the support page, it references that BIOS version 02.08 fixes something regarding the TPM 2.0 device, so the BIOS you have installed should already be good enough for a TPM 2.0 firmware upgrade.

My understanding is that all you need to do to update the TPM 1.2 firmware to 2.0 is to follow the guidance in the pdf file that I attached below and your PC is on the list of those supported by the firmware update.

See the link below:

Infineon TPM Security Update | HP® Support

This is the file you need to run the update according to the above link:
