E7470 laptop was running fine on BIOS 1.12.3 but received security advisory concerning AMT vulnerability.
BIOS 1.15.4 was just released to address concerns for security advisory CVE-2017-5689 / INTEL-SA-00075. Applied BIOS revision to the E7470, but after applying it continued to prompt for Bitlocker code after each restart. Unable to successfully leave Bitlocker protectors on without being prompted for code after each reboot so opted for reimage.
Ran through process of reimaging computer via MDT, but now receive error in smsts logs:
'ProtectKeyWithTPM' failed (2150694914)
Failed to enable key protectors (0x80310002)
Failed to run the action: Enable BitLocker.
The BIOS did not correctly communicate with the Trusted Platform Module (TPM). Contact the computer manufacturer for BIOS upgrade instructions. (Error: 80310002; Source: Windows)
Can someone please confirm issue with this latest BIOS and will need Dell to re-evaluate.
Solved! Go to Solution.
So far, I have seen two threads (Latitude E7470 & Latitude 5280) who went to the latest BIOS and now TPM is not available. Attempting to downgrade a BIOS is always risky as it could "brick" the motherboard CMOS if it fails. Makes sense that the image failed because the image was made when TPM was enabled. For now, all we can do on the Forum is gather the system models, BIOS number, and usernames and track it.
I'm having same issue on mine after upgrading my BIOS with the latest version.
Good to see another user with same issue!
[UPDATED to include model number of my laptop] I have Latitude E7470.
We are seeing this same issue with our 7470s. We upgrade the bios due to a screen flickering issue while in the docking station.
On the laptop that had been bitlocked it request a key on every reboot (yes the proper process for upgrading was followed).
On new laptop that have yet to be bitlocked it same issue as above.
We are running Windows 7 with tpm version 1.2.
Thanks for paying attention to this thread. A corporate reimaging process was applied to the system in question and all done from scratch even resetting the TPM beforehand. Although this has patched the AMT vulnerability, use of both AMT and TPM is a requirement for our environment. Since this has now affect use of TPM, we would be unable to apply this BIOS to our E7470 and E7270 equipment, so I would appreciate any push of attention to this to BIOS engineering as I can see I am not the only one affected.
Hi Chris, I have an E7470 with BIOS 1.15.4, and when I tried to configure Bitlocker, it would not recognize the TPM, so I have the same problem as these other users.
I am not really sure what this response from Client Technical Support means. Please comment on it =
That is not one of the errors that we have seen being the result of the previous BIOS updates. Usually this one would be the result of Bitlocker simply not being disabled prior to updating the BIOS. Resetting the TPM now that the BIOS is installed will resolve.
I am getting the same issue just trying to setup BitLocker. I get..
"The Trusted Platform Module (TPM) on this computer does not work with the current BIOS. Contact the computer manufacture for the BIOS upgrade instructions.”
- Windows 7 x64
- Legacy boot
- TPM 1.2
Ive tried (either single or with combinations of the following) clearing the Clearing the TPM, rebooting many times, initialize the TPM many times.
I was able to successfully setup BitLocker with BIOS 1.13.4 last week or 2. So i tried to install 1.13.4 on this laptop having the issue and bitlocker did not work still.
