He sounds like he knows something so I didn't want to go to the extreme 
of pointing out to him that there would be logs which may indicate where 
the problem may lie; but the other thing, of course, is that if the 
blue-tooth k/board is disconnected and the cpu usage goes up then the 
only way to do something like 'sudo ps aux' would be from another 
computer on a network :-) .

But, as the man said, he is happy with his situation.
