The device is very clean, used very lightly. Used for Microsoft programs. It was not used for heavy programs like editing software and games. The body of the device is intact and has protective stickers. The keyboard is not backlit. Comes with the original box and charger. The smudging below the laptop is a factory design, not a defect or scratches. It has never been serviced. Additional details are attached in the picture. I'm not sure about the screen size, possibly 15 or 16 inches. The inputs and ports are shown in the picture. For more inquiries, please send a private message. Brand: Asus Screen Size: 16 inches Operating System: Windows Storage Type: SSD Processor Type: Intel Core i5 RAM Size: 8 GB
