I found what it does, it picks from three threshold values: 84-142, 
96-138, and 75-144. I believe 84-142 was the default.

Installed Personal Solution-Pac, it says 'charging' too. And besides an 
annoying communication failure warning dialog after waking the system 
from sleep, it has no problem reestablishing communication after a bit. 
The UPS will still cause the system to wake though. There is no power 
management tab in device manager where I could prevent the device from 
waking the system.
