Have a look at this: http://andrewdcraig.wordpress.com/2013/02/18/enable-tpm-in-a-task-sequence-dell/
there is a script for cleaning the tpm ownership. With some Dell machines you cannot clean the tpm ownership without receiving a f10 prompt at next boot, some kind of failsafe security I guess. ☺ From: [email protected] [mailto:[email protected]] On Behalf Of Shareef Ellis Sent: 08 August 2014 00:08 To: [email protected] Subject: Re: [mssms] Lenovo x240 TPM - Activate via OSD Task Sequence Sorry, wrote that first email with one eye on the broken TS :) http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/sb_deploy.pdf Per the documentation it looks like to active TPM via Ts you use a script. SetConfig.vbs SecurityChip Active I reboot afterward, and run the Bitlocker task step and it fails. I think its because the TPM is inactive but it still has an owner. I completely cleared the TPM and I'm trying again. Has anyone see similar with enabling TPM on lenovo?

Using WMI to try to enable the TPM. Using SetConfig.vbs SecurityChip Active After booting, trying to enable Bitlocker through the TS and getting an error. The TPM is inactive but still has an owner. I'm testing now, but do I have to remove the owner to enable TPM via WMI?
