820-3330-B , liquid damaged no signs of corrosion. No orange light & PP3V42 was not present, so I replaced u7000. Macbook powers on, but no battery is detected. If charger is disconnected screen turns off but still have capslock light and fan still spins. Tried with a new battery, no success.
Sorry was out for the weekend, but solved. SMC_LID was good. The Battery Indicator flex was shorting the board. Thank you for the help.
