HP Recommended
Product: zbook 15 g2

Hi Everyone, 

thank you in advance for taking the time to read this message.


I know the notebook in question (zbook 15 g2) is old but it still works very well and there is not only windows 11.


I updated the tpm from 1.2 to 2.0 successfully using the Infineon tool which transforms the tpm from 9660 to 9665.
TPM12_4.43.258.0_to_TPM20_5.63.3144.0.BIN
But unfortunately the tpm is no longer visible to the operating system probably because bios 1.26 is not able to manage tpm 2.0.

Therefore I had to revert to TPM1.2 using same infineon tool and now everything is working as before.

 

However, it would be good to be able to use tpm 2.0 on other operating systems as well.

 

Is there a small chance that I have an updated bios for this notebook that could manage a tpm 2.0 ?

 

Have a nice day,

Andrea.
