HOW TO REPAIR LAPTOP MAINBOARD THAT TRIPS OFF THE CHANGER WHEN PLUGED IN

HOW TO REPAIR LAPTOP MAINBOARD THAT TRIPS OFF THE CHANGER WHEN PLUGED IN I got an HP nc600,HP nc6220,Dell D600 that shut off the AC adapter when it is plug it. When the main board was dissembled i discovered that there small eight leg components that got bunt near the charging port. Two of it was burnt and when they were change the same fault exist. So I pulled up my digital capacitance meter and tested those non polar capacitors and discovered that one of it is shorted and when they were charged the main board started working.
