liquid spilled into it, slammed into something etc., but there has been no such incident. I initially thought this was a hint of an 'external injury' - i.e. See a pattern? They are all placed next to each other on the keyboard. More specifically, the affected keys are: R, T, Y, U, I, and O. Well, in fact they do sometimes, but fail to work seemingly at random. Wether it's a hardware or software problem, it started a couple of weeks ago certain keys on my MacBook Pro keyboard don't work.
