Hi, While I'm going to the Genius Bar I still would like some input from you guys. I own a 1.83 Core 2 Dual mini and while I was using it it suddenly turned off. I checked my cables, disconnecting and reconnecting but it won't turn on. I check the power outlet and it was fine. I press the power button and there is no response or beeps at all. Obviously there is a problem but do you think it's just the power supply that needs to be replaced? I'm hoping it's not the logic board dying on me since it would put me in a position of either having to buy a new one or repair it.
