This is a mobile notebook, the "Microsoft Surface Laptop Go 3 Ice Blue (12.4/Core i5-1235U/8GB/SSD256GB/OfficeH&B2021) XK700063 (Demo unit/equivalent to XK1-00063)", which was used as a display item at a major electronics retailer. The included Microsoft Office Home & Business 2021 is a digital license version, and there is no paper product key code included. It will be automatically linked to your Microsoft account and activated. Used Surface devices often cannot be activated because the Office has already been authenticated, but this is a display item and has not been authenticated, so we guarantee that it will be activated like a new product. The battery charge cycle count at the time of listing was 169, and the maximum capacity is approximately 89%. 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 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 ■ Key Arrangement Japanese keyboard ■ Wireless LAN Wi-Fi 6(ax)/ac/n/a/g/b ■ Accessories 39W power adapter
