Use the flat end of a spudger to lift the I/O board connector up and out of its socket on the logic board
Be sure to lift straight up on the connector as you disconnect it from its socket. The socket is very deep on the logic board and prying it from side to side may damage the logic board
My computer doesn’t have any audio device whenever I look at the “device manager” (I don’t remember the Mac OS name). It started after I dropped it almost perpendicularly to the floor, so I wonder whether the problem is with this daughter board or the main one… 🤔 Any ideas? The USB and magsafe ports work, but not the embedded microphone, nor the output jack, nor the speakers. :(
The I/O board cable was not fully seated on the main board. I guess the shock made it move because the adhesive was already ripped and did not absorb the shock.
