Won't power on even after replacing logic board.
This macbook won't turn on. There are no sounds, no lights, anything. It's completely dead. After attempting to reset SMC, PRAM, etc. I went ahead and replaced the logic board. Installation was professionally done, but it still doesn't work. In fact, it's exactly the same as before.
The DC jack does light up (and turn orange if charging, green if battery full). But it also did that before replacing the logic board.
What else could it be? Keyboard/power button?
Is this a good question?
