It's trickier than you think. For instance, the power might go out, the
computer might shut down, then the UPS would drain the batteries and
shut down. Next, the power flickers back on, UPS starts up and turns on
the computer, and the power goes out again---but because UPS battery is
empty, the computer crashes hard. Such power flickering is actually
fairly common in brownouts.
