Hello there, so as suggested, I do a new question.
I try to save my Mac from water damage which was fully working on battery but not charging, and I try with a different magsafe card, without being careful I used for 3 seconds a used one for my other macbook early 2015 but 13", so I guess short circuit to the motherboard because with a new 11" magsafe board no light at all ;(
Can I buy a mid 2013-2014 11" motherboard and replace my early 2015 11"? All same connectors look similar but maybe some circuits are differents. Online I found yes and no. If someone did it with success I would love to know.
