My Dell XPS 15 9550 stopped charging the battery and I would get a warning on booting “Alert! The AC power adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available.”
The solution is pretty simple. Requires a Torx 5 and Phillips 0 or 1 to open the bottom cover. Also need some cardboard or something else that’s stiff.
