I have a 2017 13” MBA that will not power on. Visual inspection shows no liquid damage, and the liquid indicators are still white. There is a component, R40G L27F, that seems to have leaked its contents onto itself, but not onto the MLB. I haven’t been able to find this part by the code. Is this likely what the problem is? I’ve also checked the I/O board, and it doesn’t seem to have blown a fuse, at least by sighting it alone.
This is a induction coil nothing liquid inside. The shell is compressed Iron dust what you are seeing is rust! The liquid markers don’t always tell if the system was wet and in many cases I’ve seen condensation being the cause. People forget when they are in a humid climate and they exit a nicely cooled office or home the cooler surfaces will act as a magnet pulling the moisture out of the air! Just like a cold can of soda sweating! So… Lets see if we can figure things out. What is the color of the MagSafe plug Amber or Green?
