Charging diagnosis
Tell a faulty laptop DC jack (charging port) apart from a bad charger or battery, and know what a charging-port replacement involves.
Charging only at a certain cable angle or a wobbly port points to the DC jack, not the charger.
Confirm the charger is good first with a known-good adapter.
Jacks are cheap; fitting may need soldering depending on the model.
First test with a known-good charger of the correct rating. If charging is still loose or intermittent and the port physically wobbles, the DC jack is the likely fault. A laptop that runs only on AC points to the battery instead, and no lights at all can be the charger.
Some laptops have the DC jack soldered directly to the motherboard; many newer models use a jack-on-cable that plugs into the board. A jack-on-cable is a straightforward swap once the laptop is open; a soldered jack needs soldering and is best left to a technician. Match your laptop model and the existing jack type before ordering.
Charging only when the cable is held at an angle, a loose or wobbly port, heat or sparking at the plug, or intermittent charging not fixed by a known-good charger all point to the DC jack.
If your laptop uses a jack-on-cable, yes — it unplugs from the board. A soldered jack needs soldering. The product page states which type your model uses.
