MacBook A2681 Not Charging Issue

[tipoti]

Hello,
Some water got into the Type-C port, and the sockets were in bad condition. I replaced all three sockets with new ones.
The device turns on, but it doesn’t charge at all, and the charging indicator doesn’t appear.

There is no other liquid damage on the motherboard or the device; it is completely clean.

Did you test with known good battery?

 

[tipoti]

No, I don't have a battery, is the battery broken?

 

[tipoti]

If the battery was broken, wouldn't it say it wasn't charging?
There is no charging sign

battery cycle 275 capacity 86%

So battery is recognized by macOS?
Does it turn on with charger alone?

 

[tipoti]

Yes, I already mentioned that the device turns on.
I also provided the battery cycle count and capacity information.
So yes, the device turns on but does not charge. It shuts down 1 second after unplugging the charger because the battery is at 1%.

Check diode mode to ground on SCL/SDA lines of battery bus.
Also check all circuits from pages 24 & 26.
