Last night i was working with my computer at night and decided to turn on the keyboard backlight ( a feature which I don't use much, but appreciate in certain situations). While F8,9,10 all seemed to perform their function turning on teh backlight and raising it to the max, the backlight did not turn on at all. The software behaves just as it should, not allowing me to turn it on in high light conditions etc, but i get no backlight.
I do not now for how long this has been going on but recently i installed leopard had my top cover replaced (bad track pad button). I'm really hoping this is a leopard bug in some way. I've been to the apple store WAY too many times.
