This 2017 MacBook Pro still runs and operates perfectly well while plugged into power. It includes the AC adapter and extension cable in box. The battery is malfunctioning and will not hold a charge. The keyboard is also in bad shape. The space bar is broken (but still functions) and the Volume Up key is missing entirely. As is the case with most laptops with the butterfly keys, this keyboard is sticky and frequently misses inputs or repeats keys. The chassis shows signs of wear with a couple of dents and scratches I tried to capture in the pictures. Feel free to ask any other questions you may have.
