Upgrade from TPM 1.2 to 2.0 on a Dell Precision T7610

Solution 1:

I've had a fair bit of experience recently with upgrading TPM chips from 1.2 to 2.0 on Dell laptops, and I'm afraid if there is no firmware upgrade available from Dell, you're out of luck, at least for now. It's possible that Dell might release an upgrade utility for this model in the future, but I think it's unlikely given that they have already done so for other models of a similar age.

The chip is not replaceable without replacing the entire mainboard - we've had a small number of TPM failures and a mainboard replacement was the route Dell went when it came to warranty service. If Dell don't have an upgrade utility available they don't have mainboards with a 2.0 TPM firmware either.

Your question doesn't specify why the upgrade is needed. Depending on your issue there may be another solution, so you may find it worthwhile to create a separate question with more details of the root problem you're looking to solve. If it's BitLocker related, you may well be experiencing the same scenario we did.
