Ok guys, this is a two-part question. Recently my Macbook (specs as per title) powered off by itself and couldn't start up again. In recent months it has done that, and it was able to restart but it would get to the grey loading screen halfway and then shut down by itself. If I tried restarting several times, one of those times it would be successful. I never found the exact reason why this was happening. Note, the battery was also bulging at that time, and I guessed it may have something to do with that? But was still working so I left it at that.
But this time, it can't start up at all. Battery shows full. Tried disconnecting the battery and using power cable only. Also no success. So my guess is it's hardware related? Logic board maybe?
The second part is if I do have to have to replace the logic board, might as well take the opportunity to upgrade if possible. What's the latest model of 17" logicboard I can replace with for my model?
