As of late my friends Macbook has suddenly ceased to to turn on. I took it upon myself to try to see what the problem is and I think it is an issue with the logic board. Yet, I would still like a second opinion. What happens with the Macbook is that I can plug it in the charger and it will still receive a charge and the front light will begin to flash but it still wont boot. Other than that the power button does not boot up the Mac at all. Ive tried using different RAM and resetting it, tried a different HD aswell. Anyways let me know what you think. Thanks
