The charger of microsoft surface pro 4 has suddenly stopped working. I don't know what the issue is because it was working fine before. I tried plugging it in different sockets and cleaning the connector but that didn't seem to work. I checked the connector with a tester to see if the current is reaching the connector. That didn't seem to be the problem because the current is reaching the connector but when i plug the connector in the surface the light on the connector, which is supposed to turn on upon connection, didn't turn on and the surface did not charge. So i really can't figure out what the issue is. Somebody help me!!!
