If the one on the PC case got stuck, I would expect the machine to
power down. So look for a key on the keyboard. As I said, I can only

It confirms what you posted before. Swapping keyboards may be helpful
in diagnosing the cause. It might be the only solution too. Otherwise,
I can only reiterate my suggestions for masking the symptoms.

116 agrees with KEY_POWER in the source file.
