I realize there is a thread for the Asus ultrabook series (Ivy Bridge Zenbook with FHD IPS screen UX21A UX31A UX32A UX32VD). However, there is already so much material in that thread that it is difficult to find answers about a single issue.So, here's the question, is it possible to turn off keyboard backlighting on those ultrabook and have the computer remember it! I know about Fn F3 to turn down keyboard backlight but it keeps coming back.

I'd like to be able to turn it down to minimize battery usage (while having it available if/when I need it).Thanks.
