I spilled some water on my keyboard and gave it in to a shop for repairs. They quoted a value that was too high for replacing the trackpad so I got it back. They seem to have messed up some of the stuff like leaving the battery disconnected when they handed it over to me. I just started noticing that the device does not seem to realize when the clamshell is closed. Anyone knows where the sensor for the lid is located for this device so I can have a look at it? Thanks a lot!
I can’t be sure as I have not seen the system physically. But I think the iFixit guides and parts listings gives us a good clue! Typically Apple places the Hall sensor along the left or right sides of the logic board or I/O board depending on the series. You’ll want to verify by using a steel paper clip sliding it along the inside side of the display lid to locate the magnet. making note with a piece of colored tape or post-it marker fold the lid down and where the pointer falls is where the Hall sensor is located. So looking at the logic board and the audio jack board its clear the sensor is not present on them. The next two parts is the left and right speakers. I do see extra contacts in the right speaker and that leads me to believe the sensor is hidden within it. Left speaker connector
