I couldn't power up my macbook pro so I had apple look at it. They replaced the logic board and it seemed OK but now I am having the same problem. I tried the option command p r trick and the Mac powered up.The Mac sometimes work without this trick but most of the time I need this trick. Do I have a problem with the battery or is there a problem still in the logic board?
