Okay... This is the most obnoxious computer problem I've ever encountered... I'm yet to figure out a pattern, but my Macbook Pro's keyboard will just stop working for several minutes at a time at random points in time... Even if I hit caps or num lock, they don't turn green. Sometimes it'll just happen once every few hours, but I was in class the other day and it would work for a minute, then not work for a few, than work for another minute, etc. Quite frustrating... Anyone have any clue what might be up here?
