No TPM available in HP ProBook 450 G1 depending on the BIOS version?

HP Recommended

Hi everybody,

 

we have several (>10) HP ProBook 450 G1 Laptops in our company. At most of them, were are not able to activate the TPM chip (and ultimatively BitLocker). It seems to be dependent on the BIOS version; a few of these laptops with outdated BIOS versions have the option available, so I assume a BIOS update disabled the option to activate the TPM chip. The fun part is that in no BIOS changelog I found the notice "this BIOS update will permanently disable the TPM chip" or something similar.

 

I found several entries in HP forums adressing this issue:

TPM has dissapeared after BIOS upgrade

Pro Book 450 G1 Enable BitLocker

Unable to enable TPM HP Probook 450 g1

(...)

 

Is there any solution to this? A BIOS downgrade? A particular key combination?

Thank you and kind regards,

Ken Adams
