What this part does
The DC jack is the small socket where the charger plugs into the laptop. It is soldered to the motherboard or connected by a short cable. Every charge cycle puts a little strain on it, so it is a common wear part.
Signs you need a new one
- The charger plug feels loose and charging cuts in and out.
- You must hold or tilt the cable to get power.
- A burning smell or a sparking sign near the socket.
- The charger light is on but the laptop shows no charging.
- The inside pin of the socket looks bent or dark.
Check this before you order
- Check if your jack is on a cable (with a plug on the end) or soldered straight to the board.
- Measure the plug tip size and see if there is a centre pin in the socket.
- Look at the shape and number of pins or wires on the old jack.
- Try another charger first. Unstable power in your area can damage chargers, so rule that out.
Fitting: Technician recommended
Soldered jacks need desoldering and careful work on the motherboard. Cable-type jacks are easier to swap. Disconnect the battery before any work, and never test with a damaged socket for long.

Common questions
Can voltage spikes harm the DC jack?
Spikes mostly harm the charger first, but a bad charger can overheat the jack. A stable power source or a surge guard helps.
Is the jack or the charger faulty?
Test with a known good charger of the same output. If the second one also cuts in and out, the jack is likely at fault.
Is a cable jack better than a soldered one?
Neither is better. You must use the type your model was made for.
