Really? Turning on machine at some random time seems dangerous to
me. Airplane is one example. Or imagine closing lid than going

kind of vibrations when powered down, but I do not think it would
survive them with disk spinning...

IBM was calling it "redisafe". I'm not sure how fast it killed the
batteries...
