I'm just curious to see if anyone else is having this problem. I recently bought a 20" iMac G5. I tried plugging it directly into the wall, and then into a UPS system (a battery backup), but whenever I wake the computer from sleep or turn it on after a complete shut down, it flips my circuit breaker in my apartment. Now, when this happens, I usually only have one or two lights on in my apartment. I'm not running a vacuum or my microwave, or even my TV, so the strain on the circuit is not great at all. I find this very strange since the iMac is supposed to be Energy Star compliant. Any advice, or is this just a fact of life?
