>Well, I guess it works because shorting the power plug actually means unplugging the computer? I´ll bet that just unplugging it for a few seconds will also solve the problem, the rest is just to entertain or distract you from the real problem.
That is what I understood from your previous explanation - so let me rephrase the question: why would unplugging the cable work?
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
