"He who marches out of step hears another drum." ~ Ken Kesey
My UPS included software that saved files being currently worked upon and automatically shut things down properly.On a related note, a friend just fried something or other on her computer, and it was apparently due to, or at least reportedly helped by her old wiring, and circuits being overtaxed.The folks who built her new one, suggested (insisted) she also get a UPS. When it was plugged in, a red light illuminated, apparently indicating that her wiring is funky!I am assuming that it is detecting that there is not enough current.
