We repair laptop charging ports at our workshop near Castle Hill: loose or broken DC jacks, DC-in cables and worn USB-C ports, from $189. The final price depends on how your laptop is built: a jack on a plug-in cable, a jack soldered to the motherboard, a USB-C port, or damage to the board around the port.
Phone advice is free on 02 8428 9224. A hands-on diagnostic is $150, waived if you go ahead with the repair. Repairs carry a 12-month warranty on parts and labour, covering the same fault. This page covers laptops; for other devices, ring us.
Charging port fault or charger fault: three checks
A port fault stays with the laptop; a charger fault follows the charger.
- Wiggle test. With the charger in, move the plug gently up, down and sideways, without levering it. If the charging light or the Windows battery icon flicks on and off, the port, its solder joints or its cable is at fault.
- A known-good charger. Try one with the same plug and at least the same wattage. If the laptop charges, your charger has failed. If it behaves the same, the port or the board is the problem.
- The charging light. On Dell laptops, with the laptop off and the charger in, no light means power is not reaching the laptop or the charging port has failed, and blinking amber means a battery or charging problem (Dell's AC adapter troubleshooting guide). Other brands use their own light codes.
Then look into the port with a torch. Fluff can stop a plug seating (Dell suggests compressed air), and a bent or missing centre pin means the jack needs replacing. If the charger and port both seem fine, see laptop not charging.

| Acer barrel | Acer laptops with a round plug | Round plug; size varies by model | Acer matches chargers by model with its Accessory Finder. Read the size off the original charger. | From $189 |
| USB-C (USB Power Delivery) | Laptops that charge over USB-C, all brands | Small oval, reversible port | Not every USB-C port takes power. Up to 100W at 20V, or 240W with USB PD 3.1. | From $189 |
How we repair a laptop DC jack or charging port
We replace the failed jack, cable or port, repair any board damage around it, then test charging before the laptop goes back. The method depends on the design.
DC jack on a cable (harness)
On some laptops the jack sits on a short cable that plugs into the motherboard. Dell's Inspiron 1564 service manual removes it by unplugging that cable from the system board, and iFixit's Inspiron 15 5584 guide lifts the jack out after detaching its connector. We unplug the old harness and fit a new one, with no soldering.
DC jack soldered to the motherboard
On other laptops the jack is soldered straight onto the board, as in iFixit's ASUS VivoBook S200E guide. We take the board out, desolder the old jack, clean the holes and pads, fit the new jack and check every joint.
USB-C charging port
A USB-C port is a fine-pitch part soldered to the motherboard or a small daughterboard. We remove it with hot air (a rework tool that melts all the joints at once), fit a new port and check the parts beside it: the PD controller (the chip that agrees voltage with the charger), the input MOSFETs (small power switches) and the protection parts, which a shorted port can damage.
Board damage around the port
If the old jack tore off pads or tracks (the copper lines on the board), we rebuild them with fine wire before fitting the new part. Burnt parts nearby are replaced at component level; see board-level repair.
Before handback we check the laptop runs on the charger, the battery takes charge and, on USB-C, the laptop agrees full voltage with a USB PD charger.
USB-C laptop charging port repair
Before blaming a USB-C port, rule out the charger, the cable and the port you are using.
- Port: Dell notes that not every USB-C port supports power delivery. Try each one.
- Charger: it needs USB PD and at least the wattage of the original. Windows can show "To speed up charging, use a higher-watt charger" when it is too slow.
- Cable: USB PD runs at 5V, 9V, 15V or 20V. Above 3A, which is over 60W at 20V, the cable needs a marker chip. Chargers over 100W use USB PD 3.1 at 28V, 36V or 48V, up to 240W, with a cable rated for it.
If a known-good charger and cable still fail, or the plug wobbles, the port or its PD controller is at fault: port repair from $189, PD controller or board damage from $329.
Why a loose charging port should be fixed early
A loose port does not tighten itself, and the job gets bigger once the damage reaches the board.
- Charging cuts in and out each time the plug shifts, so the battery may be flat when you need it.
- Soldered jacks crack their joints. A jack that keeps moving can lift the pads under it, and the repair becomes a jack plus a pad repair.
- Centre pins bend and break. Dell warns that pulling the plug out at an angle, or forcing in the wrong adapter, can bend or break the centre pin of the plug or the port. On Dell laptops that pin carries the charger ID; without it the laptop can run but not charge.
- Buzzing, heat or a burnt smell: stop. Dell treats buzzing as a possible electrical failure and says to stop using it straight away.
To protect a new jack, pull the plug out straight, by the plug. Dell says pulling on the cable can damage the cable or the connector on the computer for good (Dell's adapter damage guide).
Laptop charging port repair cost
Laptop charging port and DC jack repair starts from $189; the final price depends on the design and any board damage. Ring 02 8428 9224 with the make and model and we'll tell you which kind of repair it is likely to be.
| What we find | From | What changes the price |

Questions
How much does a laptop charging port repair cost?
From $189 for a DC jack, DC-in cable or USB-C port, and from $329 if the board around the port is damaged. Ring 02 8428 9224 with the make and model for free phone advice.
Can a loose laptop charging port be fixed?
Yes. We replace the DC-in cable, the soldered jack or the USB-C port, and repair any lifted pads under it.
Is the DC jack soldered to the motherboard?
It depends on the model. Some laptops have the jack on a cable that plugs into the board, which is the simpler repair; others have it soldered on.
Is it the charger or the charging port?
Try a known-good charger with the same plug and wattage. If it charges, the charger has failed; if the light flickers when you move the plug, it is the port.
Do you repair USB-C charging ports on laptops?
Yes. We replace the port with hot air and check the PD controller and the parts beside it, from $189.
How long does a laptop DC jack repair take?
Some jobs can be done the same day when the part is in stock. You get a timeframe with the quote; board repairs take longer.
Can I keep using my laptop with a loose charging port?
Not for long. A jack that keeps moving can crack its joints and damage the board under it; stop at once if it buzzes, smells burnt or gets hot.
Do you fix phone or console charging ports?
This page covers laptops. For other devices, ring us on 02 8428 9224.
