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

I have the same problem except I have an Vostro 5568. I usually don't update for just this reason but Dells site said this bios was an urgent update. Whats worse is my laptop is just over a year old and only a month out of warr. I can't roll back back and reinstalling did not work.

Re: Vostro 5468 - TPM not visible after BIOS update

I have a Vostro 5568 too and facing the same problem. I downloaded Vostro_5468_1.11.0 bios driver to see if this fixes the problem. Unfortunately, it doesn't.

How could an organization like Dell release drivers without proper QA? Why take something which works and then break it?

Does anyone from the Dell customer support has any update for us please?

uninstalL TPM from the Device Manager.

Next reload Intel Chipset Driver.

TPM is now intel based.

Trusted Platform Module (TPM 2.0) - TPM 2.0 is a microcontroller that stores keys, passwords, and digital certificates. A discrete TPM 2.0 also supports Intel® vPro™ Technology and Intel® Trusted Execution Technology (Intel® TXT).

@speedstep 

the Thing is that the TPM is not detected in the BIOS in the first place so obviously it's not listed in Device manager.

i tried to reinstall the Chipset driver , didn't help.

TPM is either there or its not.  It cant be added later.
