Kirk,
See, that's the thing - most UPS's "don't" have to come
on-line instantly. They're already on-line. When you plug your
machine into an UPS, you are getting filtered power from the
batteries. Most of the time, you are basically getting some high
class surge protection from the UPS, since all the power is filtered
through the batteries and converted back to AC on the output. When
there's a power outage, there's no switch to trip in the UPS to "turn
it on" because it's already "on." They are on-line all the time.
If you ran the computer headless, you really wouldn't be
using a whole lot of power with just the base unit. About the amount
of a 100 watt bulb most of the time.
