The people of Texas here got a much better way of doing it!
Just take the computer out back and use the ole trusty 12 gauge shotgun to put the it out of it's misery. Then you just pitch what is left into the local dumpster for trash.
It is truly sad though to see we are always finding ways to get rid of the things we use the most and spend a lot of money for also. Seems I rarely shoot any of my computers here and as much as I would like too! I've never tried it - yet!!!
So I do not think I'll be trying the key suicide thing anytime here soon. But it sounds like a good option to using a shotgun or my favorite gasoline and a match... There is even the ole favorite of laying it out on the railroad tracks and come back the next day to see what was left after the train has passed. But it just seems to vanish and one might figure the computer was stolen instead of destroyed???
But for those that care - I'd just besure not to be holding down any keys for too long and be good to your system. Also there is a way I believe to deactivate that set of keys or for that matter any other set of keys from doing much of anything. But you might need that - so ...
