keyboard/OS malfunction
keyboard will not output key strokes . for every key all I hear is a click. FN sleep key does work. Swapped KBs, same result. Tried different USB port, same result. mouse works fine. When inserting/removing USB cable get expected ka-chunck sound. Unable to enter PIN while booting. Select options produces PIN and P./W icons but nothing happens when selecting.. On screen KB does work. Device Manager KB reports "device working properly" Admittingly cat walked across KB just before this happened but cannot see any key(s) that would produce this problem. Suggestions?.
