It's a cable or cord that was kept inside the laptop box. I found it when I opened the box to throw it away! I've also included a picture of the box at the end, but the box itself is not included. I'll keep it until the end of August. I apologize for the lack of information, but I thought someone might be able to use it, so I'm listing it. I don't know the details, so please check the images. I am an amateur. Please refrain from purchasing if you are looking for perfection or are overly concerned about details. Also, this item is unused, but it has been stored in a closet for a long time, so please only purchase if you are comfortable with some degree of deterioration. The following is from Mercari. I'm not sure if the information is correct, so please check the images. White power cable, 2-pin plug, with ground wire. - Cable Type: Power Cable - Connector Type: 2-pin plug - Ground Wire: Yes - Color: White Thank you for viewing.
