Hi kevinnurmi,
Welcome to Sony Community!
We're sorry to hear this kind of issue. SVE14A35 is not being recognized by our system. This may be an incomplete model or a non-U.S. model.
I plugged in an external USB keyboard, and the 'c' key on that keyboard works fine.
Most likely, this is already hardware issue and this is not just the keyboard issue. This might be an internal part issue (certain part underneath the keyboard or the motherboard). We highly suggest visiting Sony Authorized Service Center for further assistance.
Regards,
Vincent
