this started an hour ago and I do not know what it is, I have usb keyboard so I can use that for the time being but I mis my bluetooth keyboard. The problem is that certain keys seem to be combined with other keys, when I press the ? i get +?, when I press = i get =/ and when I press the F11 Volume key it acts like F12 so i can only get very quite or extremely load Volume? anyone else have these issues, what should I do?"
