[Soji]

The macbook is efi locked , so I worked on the bin file to remove the password, then I installed monteri os. Everything worked well
Except that it wount wake from sleep either by closing the lid or when it’s sleeps it’s self.
it will come up either through smc reset or when I remover the battery.

Check the signals from Hall sensors.

 

[Soji]

3.414 on hall sensor pin7
3.415 on pin6
It’s like it doesn’t goes to sleep instead it shots down
The current on the ammeter goes to zero when closing the lid or when it goes to sleep itself

There are two Hall sensors.
One is connected to J6600.
Post U5255 voltages, if possible.

 

[Soji]

Pin 1 SMC_LID_RIGHT 0.014v
Pin2. SMC_LID_LEFT_R 3.4v
Pin4 LID_OPEN_R. 3.4v
Pin 6 PP3V3_G3H. 3.4v

"Pin 1 SMC_LID_RIGHT 0.014v"
Need to fix this problem.

As per schematic, right Hall sensor is on the audio flex.
A fast bypass solution, is to remove R5257 and join pins 1 & 2 of U5255.
Changing audio flex is still the recommended option.

Fixed. Thanks
