Hey! I have the same issue. All my Fn-Keys didn´t work until i installed "Samsung Settings". now they do but the only thing missing is the backlite. The standart PS/2 Keyboard is allready shown in the device manager. I´ve reinstalled the driver whithout luck. Is there anyone who has another solution? Something i could try? Thanks a lot and excuse my bad english !
