Activate Bitlocker via CMD

Hi all,


we actually have some problem activating Bitlocker Protection on our 3rd gen X1 Yoga (20LES1BM00)


Our script does this operations:

manage-bde -on C:
manage-bde -protectors -add C: -recoverypassword > c:\Users\%username%\Documents\Bitlockerkey.txt

(after this the key will be copied to our file server)


After a reboot the crypt process should start. At least he does on all our other notebooks (HP, Lenovo X1 Carbon, Lenovo X1 Yoga 1st gen...)


When I enter:

manage-bde -status

BitLocker Drive Encryption: Configuration Tool version 10.0.17763
Copyright (C) 2013 Microsoft Corporation. All rights reserved.

Disk volumes that can be protected with
BitLocker Drive Encryption:
Volume C: [OSDisk]
[OS Volume]

Size: 474.96 GB
BitLocker Version: 2.0
Conversion Status: Used Space Only Encrypted
Percentage Encrypted: 100.0%
Encryption Method: XTS-AES 128
Protection Status: Protection Off
Lock Status: Unlocked
Identification Field: Unknown
Key Protectors:
Numerical Password

Latest Driver and OS Updates are installed. When I do the same process via GUI (save the key on a USB drive) it works without problems.


Someone has an idea how we can fix this?


Thank you in advanced

Re: Activate Bitlocker via CMD

The problem is that the TPM protector is not added automatically like it happens on all other models, don't know why not on this one. Maybe a driver problem...


To add it manualy:

manage-bde -protectors -add C: -tpm
manage-bde -protectors -enable C:


Maybe it helps somebody...
