Bitlocker activation HP ProBook 640 G1

[Strahle]

Hardware HP ProBook 640 G1, current BIOS

When I try to activate BIOS manualy, I am getting the message Access Denied.

I could fix the problem, booting the computer, entering BIOS and select „TPM Reset to Factory Defaults“

My really problem, is that I want to do this auotmated by using BCU inside my Tasksequence of SCCM.

If i use BCU to reset the TPM chip i am getting this enty in my log.
