Q: Option disappeared: "Automatically illuminate keyboard in low light"

Greetings,

 

My backlight keyboard use to work, but now it doesn't and the option to "Automatically illuminate kayboard in low light" is missing.

 

1) I have done SMC reset

2) VRAM Reset

3) All other top row functions like screen brightness and sound work

4) if I press option + f5  or option +f6 the keyboard system preferences window opens up.

5) nothing happens at all when f5 or f6 is pressed alone.

 

Did apple remove support for my backlight in Mountain Lion 10.8????

    Hi,

    I am also having the same issue, keyboard backlight is inactive, noway i cam make it active.

    In the key board system prefrence "Automatically illuminate kayboard in low light" is missing too.

     

    Supersingly it all got started only after i upgraded the OS from Snow Leopard to Mountain Lion. Even though the latest software update to 10.8.2, it's not been fixed.

     

    Anyone having any working idea to address this issue?

     

    Hope apple support will come out with some solution for this.

     

    Thanks

    Shutdown the MacBook Pro.

    Connect the magsafe charger,

    Press Left hand side Opton+Control+Shift and power button togeter for few second then release them at a time.

    Restart the computer.

    Voila backlit is on!!

    Thanks
