There is a laptop with the same problem, before entering the BIOS and in the BIOS itself, the keyboard and touchpad work, immediately after exiting the BIOS they stop working, the laptop came with an embedded BIOS, there is a strong suspicion that the problem is in the BIOS, possibly in DMI or some kind of protective chip , tried different dumps - it doesn't help

post the backup of the bios as it is, the name and the complete model of the laptop, the model of the motherboard.

No changes, laptop works as well + asks for DMI data. I have doubts that the dump is native, although the serial number from the dump matches the number on the case, but there are traces of soldering on the BIOS chip.

Nothing has changed, most likely the problem is still in the hardware, thanks for helping

Replacing the hub and removing the TPM chip helped, removing the TPM separately did not help
