Key Questions Answered
Where can I get a free laptop charging port checkup around me?
The cost for a professional DC jack (charging port) repair in Niagara typically ranges from $99 to $149. JTG Systems provides free diagnostics—we never charge a fee just to diagnose the problem. You only pay for the expert repair service itself.
Direct Answer
Which computer shops near me don't charge a fee for diagnostics?
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.
Warning: The "Wiggle" Damages Your Board
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 $100 repair into a $500 motherboard replacement.Fix it as soon as it feels loose.
Soldered Right, Soldered Tight
Many cheap repair shops use generic "pigtail" hacks or epoxy glue to hold jacks in place. We don't. We completely disassemble the laptop, desolder the broken component, and install a brand new OEM-spec jack using high-tensile silver solder.
We service standard barrel plugs (Asus/Acer), center-pin jacks (Dell/HP), square plugs (Lenovo), and modern USB-C charging ports.
Is Your Charging Port Failing?
Recognize these signs before your battery hits 0% forever.
The 'Wiggle' Technique
You have to hold the power cord at a specific angle to get the charging light to turn on.
Intermittent Charging
The battery icon switches between 'Charging' and 'On Battery' repeatedly while plugged in.
Sparking or Heat
You see small sparks when plugging in, or the area near the plug gets dangerously hot.
Pins Pushed Back
The center pin in the charging port is missing, bent, or pushed deep inside the laptop.
Loose Port
The entire metal socket moves around inside the plastic casing when you touch it.
Motherboard Shutdown
The laptop shuts off instantly when the cord is moved. This indicates a short circuit.
The Repair Workflow
Disassembly
We carefully remove the motherboard to access the power circuit, cataloging every screw for perfect reassembly.
Desoldering
Using hot air rework stations, we safely remove the broken jack without damaging the surrounding copper traces.
New Jack Installation
We solder a brand new, reinforced DC jack using high-quality silver solder for a connection stronger than the factory original.
Stress Testing
We test voltage stability and verify the port holds firm even when the cable is moved, ensuring a permanent fix.
DC Jack FAQs
It's usually physical stress. Tripping over the cord, dropping the laptop while plugged in, or just years of daily plugging/unplugging weakens the solder joints holding the jack to the motherboard.
Never. Glue is an insulator and prevents electrical connection. We perform proper electronic soldering to fuse the new metal jack to the motherboard's power rails.
We test this for free. If your charger works on our test bench but not your laptop, it's the port. If your charger is dead, we sell replacements.
Most DC jack repairs are completed within 24-48 hours. We stock jacks for popular Dell, HP, and ASUS models for same-day turnaround.
Yes. USB-C ports are harder to replace (many hidden pins), but our lab is equipped with microscopes and micro-soldering gear to replace damaged USB-C charging ports.
