Hello,
I am sort of new to MacBook repair, there is an issue that has me perplexed. I have a 2013 MacBook Pro logic board, whenever I put it in a top case and turn it on certain keys don't work and its the same every time. I tried 5 top cases, the likelihood that all top cases had the same broken keys is Impossible I think. My guess was that it was maybe the logic board itself or maybe a firmware issue, I checked the ports on the board everything looks fine , I upgraded to Big Sur thinking maybe it was a firmware issue but nothing else changed.
I'm just posting on here asking if anyone had ever seen this issue and if they've found a fix just in case the upgrade does not do anything.
I put a screenshot besides the num keys and the F-keys those are the keys that wont work.
