Power adapter DC/IN plug with cable for Lenovo laptops, replacement DC input connector cable

This replacement DC/IN plug with cable is designed for Lenovo laptops and provides the DC input connector and cable assembly used to link an external power adapter to the notebook’s power jack. The assembly replaces damaged or worn input wiring to restore stable power delivery and battery charging in compatible Lenovo models. It is intended for repair or component-level replacement and matches the physical interface of the original DC input connection.

Advantages

The cable-and-plug assembly restores a direct power path between the external adapter and the laptop battery charging circuit, eliminating intermittent connections caused by frayed wires or a broken jack. As a single, ready-to-install unit it reduces repair time compared with individual soldering of wires and can preserve existing internal harness routing. The replacement part is compact and built to match the connector orientation and insulation used in Lenovo notebooks, helping ensure proper fit and safe power transfer.

Suitable for

• Repairing a laptop that won’t charge due to damaged DC input wiring
• Replacing a loose or intermittent power jack connection
• Component-level laptop repairs where the original DC input assembly is defective

Key specifications

How to use

Power off the laptop and disconnect any external power source.

Secure the connector and routing with the original clips or adhesive points to avoid strain on the cable. Reassemble the laptop, reconnect the external adapter and verify that the device charges and receives power normally.

Recommendations

Use correct electrostatic discharge (ESD) precautions when handling internal components. If unsure about disassembly or soldering, seek professional repair service to avoid damage to the motherboard or other internal parts. Test the replacement with the original power adapter rated for the laptop to confirm proper voltage and charging behavior.
