TPM 2.0

MrDanne over 7 years ago

Hi,

Have a Lenovo X260 with TPM 2.0 (and also 1.2) and Windows 10.

When installing Sophos SG I got "Bitlocker could not be enabled" but when I changed TPM version to 1.2 in BIOS it worked fine.

Is Sophos 7.00.2.23 incompatible with TPM 2.0 ?

Hi MrDanne

Sophos 7.00.2.23 is compatible with TPM 2.0, hence am sure the issue is not about the TPM compatibility.

Ok. Do you have any idea why it won't work when 2.0 is enabled?

Hi MrDanne

To enable BitLocker Drive Encryption with TPM and PIN on machines that are installed in Legacy (BIOS) mode without re-installing the Operating System, the Security Chip Setting in the machine's firmware needs to be changed from 'Intel PTT' to 'Discrete TPM'

I had a similar problem with a DELL E5570 laptop. Solution was enabling UEFI mode in BIOS. But the OS had to be reinstalled afterwards.
