I know it's not a big deal, but my 17" i5 keyboard has an annoyance one key (the %/5 one) is at least double the brightness of any of the others. It shines through like a beacon, as if all the others have some kind of diffusing material under the key while this one is just raw, much stronger light. Solution... I turn off the backlit keyboard. Simple enough. But has anyone else noticed this rogue light on their keyboard? It's no minor difference and very distracting when the keyboard is lit.
