Hello, I've bought few days ago a Toshiba Satellite C660-11L laptop and after not more than a day I started having this problem that appears and disappears itself. When I hold some key repeating, it starts well but after 10-20 letters stops for half a second and then the same happens in an interval of 3-4 seconds. This way I can't type normally(right now too) as whenever it happens for me to type a letter during that "half second keyboard block" it just does not appear. Any clues? Am I causing it somehow or something is wrong?
