Surface RT 128GB Memory: 4GB Windows 10 Pro Initialized Dedicated keyboard Power adapter *I don't know the details, so please understand that I cannot answer any questions.* Year of manufacture unknown (Junk) The internal battery has deteriorated, so it only lasts about 30 minutes from a full charge. Recommended to use while connected to the power supply. The power switch is not very responsive, and it sometimes starts up smoothly, but often requires pressing the button firmly to start. There are some scratches on the screen that are not visible in the images, but they are hardly noticeable once it starts up. The connection part of the charger to the main unit is magnetic, but sometimes the contact was poor. Keyboard has shine. Response was good and could be used without problems. The touch panel was working without any issues. No returns accepted. Thank you. Series...Surface Storage capacity...128GB Network...Wi-Fi
