Hi fellow repair gurus,
Liquid damaged A1707 was stuck on 5V. I replaced corroded CD3215 and SMC now successfully raises voltage to 20v.
The fans spin, the screen comes on and displays a "low battery" sign before the machine shuts down.
After that the screen and fan stays off but PPBUS_G3H continue to toggle every 4-5 secs between
- 11.4v (and 170mA current draw on usb-c power meter)
- 12.6v (zero current draw)
The toggeling occurs when battery is connected but regardless if external usb-c is connected or not. It seems...
