Lenovo Laptop Charging Port & DC Jack Repair in Nallasopara East

How we handle it from Nallasopara East

1. Step 01

   Fault isolation with known-good parts

   We test the adapter, the port, the charging circuit and the battery separately using known-good parts, so we replace the component that is actually faulty. We confirm the exact Lenovo model before ordering any part, so what goes back in is a genuine match.

2. Step 02

   Board inspection under magnification

   The port area is examined under the microscope for arcing damage, lifted pads and corrosion — all of which change the scope of the repair.

3. Step 03

   Written quote with the real scope

   If the charging circuit has already been damaged we tell you now, with photographs, rather than discovering it after you have approved a simple port swap.

4. Step 04

   Controlled desoldering

   Board preheated to avoid thermal shock, then the old connector removed with hot air at controlled temperature so the pads survive.

5. Step 05

   Pad cleaning and repair

   Pads cleaned and re-tinned, and any lifted or burnt pads rebuilt under the microscope before the new connector goes on.

6. Step 06

   New port fitted and reinforced

   Replacement connector soldered and, where the design allows, mechanically reinforced so future cable stress goes into the chassis rather than the solder joints.

7. Step 07

   Charge cycle testing

   Full charge and discharge cycle with current measurement to confirm proper charging rate, plus data and display testing on USB-C ports. Collection from Nallasopara East is typically 45–60 minutes from your call.
