Squarry;
First of all, the PC hardware MUST be Soft-Shutdown capable for the UPS to be able to shut it down when low-battery is dictated. In other words, for you to see a true benefit of the UPS, your PC must be able to shutdown and turn off itself when you click Start, Run, Shutdown (Not just powering down the OS).
2nd, make sure the system is communicating with the UPS by checking for the UPS's icon on the right hand corner of your task bar or from the screen saver tab of the display properties.
3rd, take some time to re-examin any available documentation. The answer to the mistery might be in between the lines. A visit to the manufacturer's websit will also be helpful, as every vendor have their unique configuration guidlines.
From my experiece with APC's PowerChute Shutdown, the software should be able to execute the shutdown on its own without further configuration other than basic install. The more advanced version for network servers, has a user-configurable options to run any commands or set number of minutes to wait before initiating a shutdown.
goodluck
