I found a lot of humor in your anecdote that the light sensor had to be replaced. In a similar vein, a family member had a hardware issue in their laptop where some keys would not register some of the time (moisture). Their understanding was that they did not press hard enough for the device to register the press. This confusion between the boundaries of electronic and mechanical problems led to some mocking. If your anecdote can be taken at face value - they could find some respite in the fact that by pressing the keys too hard they could damage some peripheral electronic parts.
