Sadly, we're just too far down the electronics food chain to be told the truth about this matter. I learned the secret from an engineer at IBM. It's called "Percussive maintenance." We've all know there's a spot on every piece of equipment that--if hit properly--would make it work. We just didn't know there was an actual process involved. In the spirit of how this secret was passed along to me, let's just keep it between us, O.K? Don't tell anyone else.
