Trackpad and Keyboard Only Work at Login and After Loggin In
Hello! I have a 2013 MacBook Air 13” A1466 whose keyboard and trackpad only work once you get to login screen. Because of this, I am unable to boot into recovery mode, boot options, or hardware test with the internal keyboard. If I attach a bluetooth keyboard I am able to boot into these options. The board suffered a little bit of liquid damage and was transplanted into a new machine. Apart from not being able to use the startup boot options it seems fully functional.
I booted into AHT with external keyboard and it says there may be issue with trackpad and keyboard but they do work fine once you get to the login screen! I’ve tried SMC and PRAM reset to no avail.
Any help would be appreciated!
