If your Dell laptop says it’s plugged in but the battery won’t charge, the problem is usually one of three things: The charger isn’t being detected correctly (wrong wattage / “Unknown” adapter / bad port) Charging is intentionally limited (battery charge threshold, “Primarily AC Use,” or Dell charging settings) The battery or charging hardware has
