I have a Dell XPS m1330 (Intel Graphics) laptop, the problem I am facing is that the laptop runs fine on battery power but it doesn’t recognize the AC adapter. I have checked both the adapter and battery on a different M1330 and they work fine. I have taken apart the laptop to see if the dc jack was faulty, when checking with a voltmeter on the pins showed the full 19.5v dc. Do you guys know what is the faulty part? Is it the charger board?pls help
