Hi, I’m not positive, but, it’s likely that you’d see something in the System Log if system access to the keyboard was lost. If it is some other issue more related to software freeze-up, it may be more difficult to find. Take note of the specific time that the problem occurred so that a look in the log file is more directed. If you have those times logged yourself, the Service Tech may be able to better locate the problem. These sorts of issues are rare and are usually caused by circuitry problems, therefore, replacement of the keyboard itself is a real possibility.
