Just doing some work on my MacBook happy as larry, this has happend before but I have never thought anything of it.. the backlight on the keyboard has turned off and when I try to change the brightness I get some sort of disabled sign.

Im sure a restart will sort this but does anyone have any idea's what this is and why it happens?
