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.
