When a laptop wont charge, most off you would assume the charger has blown, well I wouldn’t be so sure. Often we find that the power socket on the laptop itself is what has failed. In order to repair the power socket, we have to strip the laptop down to nothing and remove the motherboard from the system (if the socket is soldered to the board). We then remove the old one and replace it with the new one using a rework station. The laptop is then put back together and tested for a full charge before going out to the customer.
