Check the Mos-fet in power section of the mother board.

Down side of the Mother Board, Near the

Check the mosfet connectivity by multimeter.

Measurements with Plugged BATTERY AND Ac Adapter

Plug the battery and AC Adapter to mother board and test with multimeter.

PQ208- Left Side 12.0 to 12.8. Not(18.5V or 19V )
PQ208- Right Side 18.5 to 19.5V
PQ201  -Down side 18.5V to 19.5V
PQ201 Up side 3.5V -12.5V
PQ 202 up side 3.5V - 12.5V
PQ 202 Down side )0V

PQ203 .19.5V-other side 18.5V
PQ204  18.5 V and other side )0V

IF Measurements both sife of PQ208 voltage are 19V or 18.5 .and PQ201 are same you have to check mosfets after remove the mother board
