Ok any tips to scratch the silicon without breaking everything? Should I try to heat it with a hairdryer or something?

So indeed I never get 3Volt on pin 25 as far as I can measure… so I haven’t tried the magnet indeed… For now based on what’s happening with the brand new audio flex I’m thinking there is a problem with MLB I’ll retry a second ultrasonic bath and if nothing happens I’ll bring it to someone with...

"I already explained you how to check if original right sensor works. Why don't check???" ===> I'm under the impression that I've checked everything you shared already. please tell me, what did I miss? What haven't I tested already? By the way I tried with 2 other audio flex (so 3 new in...

Ok but I’m measuring 300k ohm… (even though I should measure 1meg based on the schematic) And I tried linking tp hall_sensor_right + tp hall_sensor_left and the signal doesn’t die and stays at 3v on both tp (Even with audio flex plugged in and touching no other resistors) So what do we...

Ok that’s what I thought. Do we agree that if there was corrosion to ground I would measure 0 Ohm between hall_sensor_right and ground? If that’s not the case we can safely assume it’s not a short, correct? Or is ground not the same circuit accross the MLB?

any tips to measure those voltage when the audio flex is connected? Cause there is no tp and the pins are not easily accessible… when the audio flex is not connected, I do get 3v on pin 27. Regarding pin 25, why measuring from it rather than TP hall_sensor_right should be different? There is 0...

Ok so I do locate the sensor on both flex, but it's covered/protected in some sort of silicon. so I can't really access it, without removing it. I'll try to do that on the old one just to see if I can measure stuff there directly. Other than that I did measure voltage on J6600 pin 27 and pin 25...

Hi, So update on this. I have tried with a brand new audio flex thinking the right sensor was faulty. But no improvement at all. I still can put my mac to sleep only with left sensor… as if I haven’t changed anything. I did a few measure and I do have 3.3v on TP LID_OPEN and TP SMC_LID_LEFT...

Cause I don't have experience with micro soldering and don't want to mess it up, can I actually unplug the corroded right sensor by unpluging the audio connector on J6600 and then connecting the 2 TP TP SMC_LID_RIGHT with TP SMC_LID_LEFT ? Can this work to isolate the problem?

Ok thanks I'll see what I can do ;)

Sorry for the esthetics. "Both hall sensors are connected to SMC too" => Ok so you are saying that it's expected that we need 2 hall sensors with high signal to wake the computer right? Can I try the fix above without removing anything and just connecting TP SMC_LID_RIGHT with TP SMC_LID_LEFT...

Thanks. I'll see how I can try that. (don't have much experience with micro-soldering etc). If there is anyway to check/test the audioflex sensor, it might be less complex for me without micro-soldering to just change the audioflex completely? In the meantime if I look at schematic, I'm not...

Hello, I'm new to macbook repair but after spilling some water on my macbook I did an ultrasonic bath of the motherboard already. Everything works fine except after closing lid. From the schematic, I see that there is 2 hall sensors, but playing with magnets, I can put the mac to sleep only...
