Silly question : is the battery plugged in? I once did that to one of our staffers, set her up with her new UPS (it was an old APC model) and went on my way. About a month later she stopped me in the hallways and asked "What is that UPS thing supposed to do? Whenever we have a power glitch it just beeps once and the computer turns off." Me, VERY red-faced, go directly to her office and connect the battery ... Silly question: Is the computer plugged into the battery back-up side, and not the surge protector side? I don't know if it beeps on power failure when there's no load on the battery. Less silly question: Make sure you don't have something like a laser printer plugged into the battery side. Those pull way too much current starting up, and most UPSes will not work if they're plugged in. I"m not sure what the ES series does, but otherones don't work at all, just immediately go into a fault mode. Test: Make sure whatever's plugged into it can take a power off condition and unplug the UPS from the wall. It should start beeping at you, and things should keep running. With bad batteries the ES-500 should beep at you occasionally and show a yellow (iirc, I don't have one of those in the office right now) Battery Fault LED. Batteries are relatively cheap and readily available at Batteries Plus....that's where we get our replacements, and the ones in those ES models are a standard size sealed lead-acid used in a lot of different equipment. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
