My MBA's keyboard light refuses to turn on at times, the indicator comes on the screen with a forbidden sign and the light doesn't turn on afterwards, has anyone experienced this?

    I have experienced this as well. I believe this occurs when the ambient-light sensor believes that there is sufficient light in the room to not necessitate the use of the keyboard lights.

    Try this: Cover the hole left of the iSight with your finger, and press the F6 key. After a while, the keyboard light should start to brighten. If you remove your finger, the lights should go out, once again preventing you from powering the lights.

    Yes, I have it switched and the timeout switched to never.

    I can get the lights to come on using Laptick but they wont witch on automatically. I think the screen has dimmed once but it also doesnt work now.

    I have tried the fixes detailed with resorting .plist, but still nothing.

    Can anyone help ?
