The update did not seem to help me.
My backlight keeps turning off to save power I guess but then never seems to turn back on... even in total darkness. Even though I have it set to NEVER on the slider in System Preferences it still turns it off... grrrr.
Is there some way... maybe a command line trick to just disable the MBA from controlling it through the light sensor?
I am happy to just do it all myself with the F5 & F6 keys
I my opinion, the keyboard light should ONLY go off when the MBA goes to sleep. Period!
It is a bit annoying to have it just turn itself off for no apparent reason.
I may try the PRAM reset, but I have no real hope for it.
I LOVE this little laptop, but the backlight really bugs me as I use it a lot at night in dimly lit rooms.
Oh well.
I look forward to any fixes... I am going to try Lab Tick and see if that helps.
