My 2 yr old PS3 Slim 120GB makes this beeping type noise randomly. It is a short, high pitched beep. It is not in a closed cabinet, and the front indicator light has never turned yellow, nor does it flash yellow when I'm directly in front of the console (when I catch it beeping).
I've never worked the console hard-no heavy game playing, well, in fact, none at all in months. It happens mostly when streaming, but a couple of times, it beeped when eject a disc. There is never a disc inserted when it beeps. Hard drive is less than half full. Hard wired with ethernet cable.
Any ideas why or what this means?
