    Hey guys.
    So I bought a 13" base model and I absolutely love it!
    The only problem is that my backlight keyboard just stopped working. I turned it completely down to safe battery, and I wanted to turn it up again but now it doesn't respond anymore.
    it only shows that sign that it is off!
    Does anybody know any solution? apple store is half an hour away and I don't have that much time to waste.

    I assume you have already tried rebooting the computer and trying the keyboard backlight again?

    The next thing I would do is reset the PRAM and SMC which may control the keyboard lighting. Instructions are on the Apple Support site.

    PRAM reset:

    SMC reset:

    Good luck....;)

    EDIT: haha ... yeah, I forgot to mention ... be sure you are in a dim location when trying to turn on keyboard backlighting. I assumed you were probably doing that.

    Yeah, if you just hold your thumb over the isight camera area on your display, the keyboard backlight should be adjustable again.

    playing a gig in the club tonight and just mentioned the same problem here and was afraid I'd have to do the pram/smc reset (which once led to unbootable system). thanks god I did read this to the end. never knew backlight is forced inactive in daylight.

    you just need to go to keyboard settings and uncheck the box "adjust keyboard brightness in low light" and its fully manual even in bright light.

    There's a setting in system preferences for auto keyboard brightness. Turn it off and you will be able to adjust your keyboard manually in bright light.

    Hi there. So my keyboard was damaged. I replaced it by the second hand one from eBay. All working now, BUT NO KEYBOARD BACKLIGHT. I tryed to put backlight plastic from new one, and from old one. NO LIGHT. On motherboard connector of keyboard backlight is 1V. I tryed to do the SMC reset also. So im writing here as a last chance to get it work again. Thanks. :(
