Backlight Keyboard doesn't work anymore!

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.

LOL, new to mac?
go somewhere dark and try again.

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

haha....

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.

Well well I never knew that

Cheers for the advice.

I love this thread. It reminds me of when I took my wife's macbook to apple cause the screen was out. They just brightened the screen and wa la it worked.

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.
