For the past 10 days my G4 tower OS 9.1 has been shutting down spontaneously so after much research and no luck I finally took it into the Apple store. They put in a new battery, ran it for 4 days and it was perfect, passed all the tests. Brought it back to the office, ran fine for 6 hours then whamo! it shut down. I find that if I leave it off overnight it will usually boot right up in the morning, last a few hours, then whamo again. Like someone pulled the plug. I've tested all the in house wiring. Am connected to 2 strips and an APC 650. Everything else on the strip runs fine. HELP please. Any ideas anyone? Cheers and thanks.
