Okay, so here's the situation. I have a 2006 iMac 20" 2.16 GHZ (Model: A1207). The other day the room the computer was in was being reorganized. Before anyone moved anything, I properly shut down the computer because I knew they wanted to move the UPS from one place to another which required that the computer be unplugged and the power cord be routed around the desk in a different way. Anyway, after I shut it down, I later came back after it had been moved. I pressed the power button to turn it on, and there was no response. I pressed it again, and nothing happened. I went through the usual things, resetting the SMC, trying different outlets, etc.
Basically I know this: when it is plugged in, there is a very faint high pitched hum coming from the machine (I assume this is normal, but I'm not sure). Every three seconds there is a very faint clicking sound. After following the instructions to get to the three diagnostic LEDs, I notice that the lowermost LED is on when the computer is plugged in. This is normal, as far as I know, and means that there is power coming in. Nothing happens when I press the power button. However, every three seconds (at the same time as the clicking sound) the middle LED flashes on for a fraction of a second, while the lower light simultaneously turns of and then back on again. Every three seconds.
Also, I plugged in a USB charging cable for a remote control toy to see if the USB ports are getting power. At the some time as the click and the middle LED flashing, the light on the USB cable that indicates that it is receiving power flashes on. I don't know how much of this information was relevant, but that's all I know so far.
Any advice would be greatly appreciated.
