Vostro 5468 - TPM not visible after BIOS update
Hi, I upgraded BIOS from 1.11.0 to 1.12.0 but after that there is an error message every boot:
"Alert! TPM device is not detected."
TPM is not visible in BIOS or Windows, drivers for everything should be the latest.
Downgrade is not possible (even as this option is selected in BIOS). Intalling the update again doesnt help.
When there will be new BIOS to repair this?
Or anything I can do more?
Thank you in advance for any suggestions

@187223 Thank you so much! This method worked for my Vostro 5568 as well and I don't see the "TPM option is missing" error message anymore. Cheers!

Seems like Dell is playing the same trick Apple uses with planned obsolescence (scam would be more appropriate)... I have the same problem as everyone else with the Dell Vostro 5568. Although @187223 might have solved it, I don't want to risk breaking up my laptop, I'd really prefer if Dell itself provided us with a new software update fixing the issue.
This is really bad publicity, we all feel like we've been tricked honestly, how should we ever trust Dell again with the devices we rely on for work?

Hopefully this will help you all, I was having a nightmare with this on one of our Dell Vostro 5468 laptops at work and managed to find a Dell Support Video on BIOS Recovery, whilst it doesn't fix the issues with the actual BIOS updates not detecting TPM, it does show you how to easily roll back to a previous version if your laptop does not have BIOS Recovery installed on the HDD/SSD, which was also my issue, hence @187223 's solution would not work for me.

I skipped over the first part of the video and followed the steps starting from formatting the USB to FAT32 and now have successfully got BIOS v1.11.0 back on the laptop and the TPM message has gone!

Has anyone had success rolling back to 1.11 from a 5468 that had gone to 1.19 ?? Best I seem to manage is 1.14.1. Seems Dell are blocking it from going back too far and gives "bios update blocked due to unsupported downgrade" when you try to recover the BIOS. We now have a useless laptop that won't work with any MS365 systems as the TPM is required.
Thanks Dell!!

Hello, seems a difficult problem. But as I understand rolling back to 1.11 thus the trick?
