I think there is an issue with the latest BIOS version regarding TPM activation with CCTK. I'm not sure if you can revert to an older BIOS to workaround the issue until it is fixed.
Make sure you are rebooting the system in between the "Enable" and "Activate" commands. Also make sure you have a BIOS password set when activating via command line.
At the BitLocker stage of the MDT sequence an error is generated that "Check to see if TPM is enabled". And sure enough the TPM is enabled but not activated.
Seems to me that the CCTK will not set this option for this particular model.
I wont bother reverting to an older BIOS version. We have around 250 laptops to build and running short on time. And I would assume the latest BIOS is best for other features, cant really justify reverting to an older BIOS for just this reason. The build team will just have to set the TPM manually before each build. Will add about 30sec to a minute for each build. Far from a show stopper.
I tried enabling and activating TPM on Dell Latitude E5430 and E6530 (both BIOS A07) using CCTK, for use with Bitlocker.
My steps are (scripted):
- Install Dell CCTK 2.1 - Set bios password - Turn TPM ON - Reboot - Activate TPM - Reboot
According to the log, everything works perfect..
Now, if i check TPM Activation status using CCTK, it returns 'Activated' - but if i check the actual setting in BIOS, TPM is ON, but it's Deactivated. Also tried running CCTK manually, same result. The Bitlocker activation script also detect it's deactivated, so encryption doesn't happen.
We're about to ship 300+ laptops, and unlike Robert i believe this is a critical error. Maybe not a showstopper, but it's forcing hands-on on a job that's supposed to be automated. So... if i'm missing something, please advice - and if not, please fix this Dell!
I opened a ticket and they confirmed there is an issue with the current BIOS version that prevents you from being able to properly set the TPM chip. They said you can either downgrade to an A02 BIOS version or manually set it in the BIOS. They are working on a fix in a future BIOS update, but didn't give an ETA.
It's an issue with the current BIOS version on certain hardware (including the Latitude E4 Series). We'll need to wait for an updated BIOS revision to get that piece fixed. As Warren stated above, if you submit a support ticket then hopefully they'll be able to divert more resources to get it fixed sooner.
