I was trying to install an optibay knock off on my pb g4 and accidentally tore off a connector from the motherboard. Some sites state that either that is the speaker cable or something that has to do with the bluetooth. Thing is everything works as normal and i cant track down the problem. I started thinking maybe it was the fan's cable but i dont really know. And so i became paranoid for the temperature on the processor. It sits around 60-65 celcius while just surfing. Is that normal? I am using an app called temperature monitor. what temperatures do you get on your g4s?
