This is a Microsoft Surface Laptop Go 3 Ice Blue (12.4" / Core i5-1235U / 8GB / SSD 256GB / Office H&B 2021) XK700063 (Demo unit, equivalent to XK1-00063) that was used as a display model at a major electronics retailer. The included Microsoft Office Home & Business 2021 is a digital license version, and there is no physical product key code included. It will be automatically linked to your Microsoft account and activated. Used Surface devices often have issues with Office activation, but this unit is unactivated as it was a display model, so we guarantee it will activate just like a new one. The battery has been charged 100 times at the time of listing, and the maximum capacity is approximately 90%. The main body is in very clean condition, but please note that the outer box has sticker residue, scratches, and stains. If a natural failure is determined by a professional within one month of the product's arrival, we will either exchange it for an equivalent product or repair it. If repair is not possible and an equivalent product cannot be prepared, we will provide a refund up to 90% of the purchase price. Please note that pixels that are constantly lit or not lit are not covered by the warranty. 【Product Specifications】 ■ Monitor Size 12.4 inch ■ Monitor Resolution 1536 x 1024 (148 PPI) ■ OS Windows 11 Home ■ CPU 12th Generation Intel Core i5-1235U ■ Memory 8GB ■ Storage SSD 256GB ■ Office Software Office Home and Business 2021 ■ Touch Panel Touch Panel Compatible ■ Interface USB-C 3.2 (Data, DisplayPort, Charging), USB-A 3.1, 3.5mm Headset Jack, Surface Connect ■ Bluetooth Bluetooth 5.1 ■ Keyboard Layout Japanese Keyboard ■ Wireless LAN Wi-Fi 6(ax)/ac/n/a/g/b ■ Accessories 39W Power Adapter
