I'll take the necessary steps. >=20 I was thinking... Maybe I'm wrong, maybe I mistaking, but isnt this TPM located inside of the CPU chip? So that issue is not specific to laptop vendor or model, but its CPU-specific. My MSI A12MT laptop has i5-1240P, Framework laptops mentioned in this thread, also has i5-1240P CPU. Unfortunately there are no such information about other affected models, but could it be just that CPU line?
