What the Service Includes
The service includes cable diagnostics (multimeter continuity check, visual inspection of insulation and plug), disassembly of the adapter brick, desoldering of the old cord, selection of a compatible replacement cable (0.5–0.75 mm² copper wires, correct plug type and polarity), professional soldering to the adapter board with flux and heat-shrink insulation, short-circuit verification, load testing with the connected laptop, reassembly, and final charging stability check. Frequently combined with laptop repair if the faulty cord damaged the DC jack or internal power circuits.
When the Service is Needed
Replacement is necessary when charging becomes intermittent (requires moving the plug), stops completely, the cable or connector overheats, sparks appear, there is a burning smell, crackling, or the adapter fuse blows. Physical damage (fraying near plug or connector, exposed wires, broken barrel plug) is also common. Most cords fail after 2–5 years due to repeated bending, poor factory soldering, or rough handling. In Khmelnytskyi we advise prompt replacement to prevent damage to the laptop’s power port or adapter board.
Work Stages
- Diagnostics: Multimeter continuity and short-circuit check, visual inspection, testing with alternate cable if available.
- Adapter disassembly: Careful opening of the power brick case, desoldering of the old cord from the board.
- Cable selection: Matching replacement with identical plug type, wire gauge, polarity, and length.
- Soldering & insulation: Wire stripping, tinning, soldering to board, individual and overall heat-shrink tubing.
- Reassembly: Securing the cable to reduce strain on solder joints, closing and fastening the case.
- Testing: Voltage verification, no-short confirmation, extended charging test under laptop load, heat monitoring of cable and plug.
Post-replacement recommendations for proper cable handling are provided to extend service life.
