Many of the fancier UPSes allow software to be running on the computer with 
a serial/USB/etc connection back to the computer. If the battery gets too 
low, it automagically shuts down the computer so it's nice and safe.

Despite the simple function, the hardware requirements for UPSes that will 
do it are going up.
