2013年8月15日 · Long story short - my keyboard backlight in T470 don`t work. Space key have a backlit pictogram, keybord FRU is 01AX 516, and PN: sn20l7283 and as far as i searched it should have backlit. I`ve question to T470 with backlit keyboard users - is backlit light up for a moment and fades down, right after turning on the computer?
