I've got a Vostro 15 5568 (LA-D821P board) with the TPM problem. ME works fine (can get data using MEInfo, the firmware is 11.8.92.4222 LP - the latest from 1.20.0 BIOS).

Downgrading the BIOS only avoids the "TPM device is not detected" alert - TPM will not work. After downgrading to 1.8.0, you can upgrade to 1.11.0 - the latest BIOS that does not have the alert.

Tried moving RC1130 to RC1131 to change TPM_ID from HW_TPM to SW_TPM but the alert was still present.

Looks like the TPM chip UZ13 (Nuvoton NPCT650JBAWX) is faulty (or has corrupted firmware) and needs to be replaced.
