Hello all,

I bought a Macbook Pro 16" M1 Pro, A2485, 820-02100, which working flawlessly but not charging. I thought battery needs to be replaced but then started reading and it seems that problem will be in motherboard.
Battery sign has cross sign and MacOS can't read battery stats. Fans are full speed but can be set down via Fancontrol software.
I did start digging into in and found out below:

Diode mode:
SMBUS_BATT_SCL: 0.529
SMBUS_BATT_SDA: 0

SMBUS_BATT_SCL: 1.795V
SMBUS_BATT_SDA: 0.948V

Can anyone help...
