    Hi all. I have a 2006 Core Duo MacBook. I shut it down the other day and nothing unusual happened. But, now when I push the power button there's no response at all. Nothing. No lights, no response, no chimes, no screen flicker.

    Yes, I've read all posts I can find on this and nothing has helped. I've followed the SMC reset (http://support.apple.com/kb/HT3964) and can't zap PRAM since it doesn't even chime. Battery shows a full five lights and the MagSafe cord shows a green LED. I've tried all sorts of booting with just battery, just power, leaving both out overnight but can't get any sort of response. I don't hear any fan motion or HDD whirring up. The power button doesn't seem to be stuck though--it's flush with the case and still gives that slight tactile "click" when depressed. I checked that the RAM's set properly.

    If it were a HDD problem it would at least like up and blink the folder icon and AFAIK.

    I'm guessing the only advice will be to take it into an Apple Store but I thought I'd just check if there are any other ideas. I live 3 hours from the closest store so I can't take it in and the computer's obviously out of AppleCare warranty.

    It's been powering my media center but it's not my main computer so I wouldn't be adverse to some experimenting and cracking it open. In the past I had to replace an AirPort antenna and HDD so I'm comfortable messing around inside if anyone has suggestions of where to look.

    The reply button's gone missing! So, I quoted this... You probably have a bad motherboard. But, you should also try looking at the topcase's connection to the motherboard/logic board.
