I have a laptop that has keys that will sporadically work & then not work.
e.g. When writing a Word doc or an email some of the letters will not type. It isn't a specific letter/key either. It is a Win7 laptop & there hasn't been any spillages or physical damage, & I have changed the keyboard settings (repeat delay/rate etc...) in the control panel, but no joy.
Has anyone have any ideas as to what is the problem?
