Hi friends.
I am writing from Chile and I have a problem in an A1990 computer, logic board 820-01041-A
(sorry for the translation)
Equipment had problems in C9081 - C9088 were replaced and equipment was turned on again, the problem is that the fans are at full capacity, when performing apple tests it indicates problems in SMC, I attach a screenshot.
Replace battery flex, screen flex, trackpad and continue with the same problem.
If they could guide the fault.

ThanksSMC.jpg

First of all, welcome to the forum!

There should be a problem with trackpad board/flex.
Just in case, disconnect screen cable and test with external monitor; do this to discard ALS issue.
