<p>A method and apparatus for reducing unexpected sensations when a user contacts a conductive outer surface of a device are herein disclosed. In one embodiment, a computer system includes a conductive outer surface touchable by a user during computer system operation, a ground conductor, and a protection device. The protection device is coupled between the conductive outer surface and the ground conductor. The protection device conducts current from the conductive outer surface to the ground conductor when the voltage across the protection device exceeds a preselected threshold voltage, and insulates the outer surface from voltages within the computer system that are lower than the preselected threshold voltage.</p> |
