Hi guys, on my previous MBP (2012 15") putting a magnet on the left side of the keyboard around the middle activated the hall sensor and clamshell mode was enabled even with the lid open. On the 2017 I cannot replicate this. I tried moving a magnet all around the edges. On a random iFixit forum post (I can't find anymore) someone mentioned that there are now multiple hall sensors as opposed to just one like before to prevent accidental sleeps better. Anyone know their exact location? The iFixit teardown of the 2016 shows 4 magnets in the display. 2 small ones near the bottom on the left/right side and 2 longer ones along the top. I tried a bunch of combinations here but can't find "the one" that puts it into clamshell mode since I don't know where the sensors are. Anyone had any luck with this? --- Post Merged, Mar 16, 2018 --- Alright I figured it out (woo!) with the help of this picture: https://d3nevzfk7ii3be.cloudfront.net/igi/mm2g6UFMIvHU5KW1.huge The magnets in the display don't perfectly overlap the ones in the case. So they need to be held a bit above the ones in the case in order to hit the sensors. They also need to be a little stronger. I tried some fridge magnets I had and they didn't activate it. I then tried a couple really small round magnets out of some toy or something that I had lying around since forever and with those it activates.
