Re: Acer - N19C2 - MB EH7LW - Sudden death
ACDET now is a good voltage to announce that the adapter is connected.
However, SDA and SCL should not be at 0 volts on this charger IC.
The SMBUS lines will be used by the EC to configure specific registers inside the charger IC.
Confirm that the pull up resistors on the SDA and SCL lines are being pulled up to +3v3. One side of the resistor will be to SDA line, other side must be to +3v3. The same for the SCL line.
