Could you elaborate on your question? What exactly is wrong with the Zero button? Does it not work at all? Does it work some of the time? Does the button not press down? How long have you had this calculator? Do the surrounding buttons operate correctly? I have never seen a TI BA II Professional, could you please shares some images of the front and back of your calculator?
