TEXT is best. Are you looking for Laptop DC Power Jack Repair? You found it! Let's get to work on your device right away—bring it in and our experienced team will start the repair while you wait.
The cost for a professional DC jack (charging port) repair in Niagara is quoted after a free assessment. JTG Systems provides free diagnostics—we never charge a fee just to diagnose the problem. You only pay for the expert repair service itself.
Most DC jack repairs are completed within 24 to 48 hours. At JTG Systems, we keep common charging ports for Dell, HP, Lenovo, and ASUS in stock at our Welland headquarters to ensure the fastest possible turnaround.
Forcing the charging cable to work by bending it creates electrical arcs (sparks) inside the jack. This generates heat that can melt the motherboard layers (PCB) around the jack, turning a simple professional repair into a high-end motherboard replacement.Fix it as soon as it feels loose.
Many lower-quality repair shops use generic "pigtail" hacks or epoxy glue to hold a loose jack in place. At JTG Systems, we performboard-level soldering and chassis alignment to restore structural integrity to factory standards.
We service standard barrel plugs (Asus/Acer), center-pin jacks (Dell/HP), square plugs (Lenovo), and modern USB-C charging ports.
Recognize these signs before your battery hits 0% forever.
You have to hold the power cord at a specific angle to get the charging light to turn on.
The battery icon switches between 'Charging' and 'On Battery' repeatedly while plugged in.
You see small sparks when plugging in, or the area near the plug gets dangerously hot.
The center pin in the charging port is missing, bent, or pushed deep inside the laptop.
The entire metal socket moves around inside the plastic casing when you touch it.
The laptop shuts off instantly when the cord is moved. This indicates a short circuit.
We carefully remove the motherboard to access the power circuit, cataloging every screw for perfect reassembly.
Using hot air rework stations, we safely remove the broken jack without damaging the surrounding copper traces.
We solder a brand new, reinforced DC jack using high-quality silver solder for a connection stronger than the factory original.
We test voltage stability and verify the port holds firm even when the cable is moved, ensuring a permanent fix.
