This is also affecting the 3 Lenovo Thinkpad T420s I have tried in all live/install and normal modes. I can only operate them with the acpi=off parameter, but in this case Standby/Restart/Volume controls don't work. Note: All 3 models have a dedicated nvidia card, which is switched off in the BIOS Menu.
