820-3332 turns on, but don´t charge

Hi,

Board don´t have water damage, with battery or charger it turn on, but don't charge.

Charger never gets a ligth, but with charger in the OS you can see the charger icon instead of the battery when I connect it.

U6900
1 SMC_BC_ACOK_VCC = 3.40 V
4 SYS_ONEWIRE = 0.81V
5 ADAPTER_SENSE =0.73V

U6901
1 SMC_BC_ACOK =3.26V
4 SMC_BC_ACOK_VCC = 3.40V
5 PP3V42_G3H = 3.42V

J6950 (without battery)
1 PPVBAT_G3H_CONN = 12.56
5 SMBUS_SMC_5_G3_SCL = 3.42 V
6 SMBUS_SMC_5_G3_SDA = 3.42V

Should I change the SMC or can it another thing?

Did you test with known good DCIN board?

What is diode mode reading on pins 4 & 5 of U6900?
Replace R6929, just in case.
