Problem description
Fixing issues related to sleep and waking up on A1707 MacBook Pro
Symptoms
- not waking up from sleep after closing
- only starts after unplugging of battery
- sleep without closing (through OS) is no problem
Solution
- Problem with one of the Hall Sensors
- SMC_LID acts normal (3.4V with open Laptop; 0V closed)
- SMC_LID_LEFT or SMC_LID_RIGHT is not acting
- SMC needs both signals to go to sleep
- Display, Keyboard, Powerbutton, Trackpad, ... are in sleep mode and don't wake up
- Solution: look at R5252, C5250, R5253, C5260, both Hall Sensor Boards (J5250, J5260) and U5255 area for corrosion --> repair
- if Tracks are missing (like my case) to Pin 1 of R5252 or R5252 a direkt connection to Pin 2 of the Hall sensor chip
