Has the UPS ever worked correctly? There ought to be a "test" button. When you push it, does it "pass"? Q: If it has never worked correctly, did you hook up the battery when you first purchased it? Not all UPS are ready to go out of the box. Some of them require a little bit of prep before you can use them. > This is 720VA, that should be plenty, right? Dunno. The 750VA is just 400 watts, the 550VA is 330 watts, the 1100 is just 660 watts, so the number in the name is not necessarily the capacity. The 750VA is "geared toward entry level computers" according to Belkin's website (I imagine the 750VA is an upgrade of your year-old 720VA). I'm not sure a dual G5 qualifies as an entry level computer, or not. I'd double-check whether you're overloading the beast. ~Linda
