I would like to ask for help, namely: I got a disc with torn pads of the battery connector. After a small design (pictured), after connecting the power supply, the charging lamp (orange) lights up for a while and no reaction. After entering windows, it does not see the battery, after disconnecting the power supply, the laptop works on the battery itself. The battery itself has been tested on a new board and works fine. The problem is the lack of power on pins 6 (BATT_TEMP_IN), 7 (EC SMDA) and 8 (EC SMCA) - not connected because I don't know where. All voltages on the other side of the board resistors PL_103,104,105, PR105,106,107,108,PC221,217,107,218 are correct. Where to look for the cause?
I have a schematic and boardview, but I don't know much about schematics.
