MacBook Pro Charge slowlyI have a Macbook pro 15'' 2010. 4 moths ago, I replaced the logic board to 2012 version because of some beyond repair damages...
Answer to: Replacing logic board with new version?Yes, you can do it because I have done with 15inch Macbook Pro. I upgraded the logic board from 2010 to 2012 (not retina). I also changed the battery because the adapter is different. Before you do it, you had better to check the guide and compare the logic board pictures.
Answer to: Possible Logic Board Upgrade?It may be possible. I replaced my 2010 MacBook Pro 15 inch logic board to 2012 version(not retina), and it works. The only problem is I have to my new battery because the adapter is different.
