Bitlocker Troubles on Lenovo T420i

Posted on 2013-11-12
Last Modified: 2013-11-21
I have a Lenovo T420i that asks for the bitlocker recovery key every time it is re-started or shutdown. The TPM is enabled and BIOS settings are proper per all the documentation I have perused. I have tried suspending bitlocker, re-starting the machine and re-enabling bitlocker. I have also tried un-encrypting and re-encrypting the drive. Group policy is locked down so I cannot modify the PCR's. I have dozens of other Lenovo's that do not have this problem on the same network. Idea's?

You even decrypted, re-encrypted and right on next start it asked for the key? That's what you say? Is it possible that some oddity is going on caused by an empty BIOS battery or by constantly connecting/disconnecting external devices or extension cards?
