MacBook Air tricky SMC

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?

There are pretty skillful techs answering questions on this forum but I don't yet know any of them being able to replace an SMC at a distance.

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.
