Wow it's been a while since I posted!
This is a weird case, it has a history of liquid spill a year ago but customer did not want to replace neither trackpad or keyboard.. fast forward for today:
A2681 turns on but not trackpad or keyboard feedback (or external keyboard and mouse) and then after a minute or so the Mac sleeps..
It's a NOT a sleep sensor or trackpad or keyboard or daughterboard or anything else (I replaced all those); it's the logic board..
Tested another locked logic board on customer's top case and it posted with keyboard and trackpad functioning..
Anybody experienced such issue with the logic board?
No signs of liquid on board, so signs of blown caps or resistors or chips.. everything seems intact..
