A2337 820-02016 - Not Charging battery, short on I2C_SMC_PWR_3V3_SCL line

[it-solve]

I2C_SMC_PWR_3V3_SCL has 0Vdc drop, traced the short to UD201. Replaced it now short is gone.
Tested the case and battery on spare board all works and charges battery.
On this board still has X mark on the battery, shows 1% and stays at 0.34A power on current. Says Replace battery

Any recommendation what else i can test without oscope?

Check diode mode to ground on all SCL/SDA lines of UD200/1.

I have short on I2C_SMC_PWR_SCL with removed UD201. Game Over?
No other shorts in the area

 

[2informaticos]

Remove UD200 and check again.
If still short, dead M1 CPU.

Nope, still short. Seems like it sent battery voltage to clock line. Thanks @2informaticos
