Chosen Solution
I buy a used MacBook Air and in the first moment it didn’t power on, so I charge him whole night and after pressing random keys+holding power button it turn on. BUT after 10 minutes it power off. So I order new battery from China and after replacement it works. BUT after charging the MacBook with Chinese battery it power off. So I took him to the local PC Service’s and they told me there is on the motherboard little chip called SMC and it is broken. Can somebody help me?
Motherboard replace.
I would recommend you spend sometime reviewing Louis Rossmann’s YouTube vids Unless you have the schematics and boardview drawings as well as a good understanding on electronics theory its a steep climb to diagnose and repair your logic board. You will still need the needed tools and access to the parts.
