    Are the keyboard and motherboard both brand new?
    Are you sure you plugged the ribbon cable of the keyboard all the way in and clamped/locked it in place? I have seen this happen many times .... you plug it in and while clamping it, it slides back out without you noticing it....

    Thanks Charles ... I don't understand the B grade?
    As per EE help:
    "....Grading at Experts Exchange is not like school. It's more like the "10-point Must" system in professional boxing; in other words, an answer is worth an A, unless it doesn't resolve your issue. If it requires you to do a little more research, or figure out one more piece of code, then it's worth a B. If you think it's not worth a B, the custom is to offer the Experts an opportunity to earn a better grade.
    Giving a higher grade has no impact on your Available Points
    I was under the impression that my answer did resolve the issue when you accepted the answer (of course, unless your keyboard was DOA in which case, nothing I proposed would have worked).
