This asus works fine on battery, but shut down on adapter in 5 10 seconds. display comes on when we start the laptop and goes off in 5 to 10 sec. Even after display off all voltages are there. cpu and graphic ic heats fine even in off state. Any idea. On battery even for 2 hrs machine works fine

Voltage the input jack path to ac_bat_sys voltage. Check if the voltage drops? The coil or MOSFET may be damaged along the way. Also check the charger.
