Recently, the same issue happened to mine and I'm about to send it out for the logic board replacement. However, I am not really secure about this at all seeing as I've read some that have been repaired were only on the path to fail once again. If you have had your MacBook Pro repaired with a logic board replacement and it has been working fine, please post here! If it hasn't you can also post. I just want to see how many of them actually are working okay after a repair. If I can get another year out of mine I'll be fine, I'll end up buying a new one when I transfer colleges anyways. Thanks.
