The Lenovo Cable GB 1M 3P (00XL076) is a mains power cord for connecting compatible equipment to a power source. Lenovo’s parts list identifies it as a GB line cord with a three-pin (3P) plug.
At 1 m long, it provides a short cable run between the equipment and the nearby power connection. The listing specifies a black cable and a flat plug, with plug-and-play use that requires no setup.
This is a practical replacement cord when the required connection is the GB three-pin type and the stated length suits the setup.
