This problem has been noted before, perhaps only occurring on BIOS 1.57 and later.[1][2][3][4][5] This model does not have an external PS/2 port, so mux does not appear to be useful. Odds of a BIOS fix appear to be low: 1.57 was released over 6 years ago and although the [BIOS changelog] notes "Fixed an issue of UEFI touchpad/trackpoint/keyboard/touchscreen" in 1.58, it appears to be insufficient. Adding 33474HU to the nomux list avoids the issue on my system.
