My dell Inspiron 3420 bios version A09 suddenly stopped charging battery , and the power icon show this message(Plugged in and charging) but my battery does not charge.
I tested another charger and another battery but did not help.
Thinking that changing bios might help,I am trying to change the bios but can't downgrade even i tried /forceit command.
I can access logic board if for troubleshooting someone could educate me about voltages of sda, scl and dc jack connector to the board.
Kindly help me.
