Fully functional. Includes: Main unit, power adapter, cable, and instruction manual only. (Software, such as a certified OS, is not included) Original box included. Price is firm, no discounts. The keyboard was used with a protective cover, so there is little wear and tear, and the white LED still looks beautiful. CPU: Core i5-3320M 2.60GHz / Memory: 4GB / SSD: 120GB / DVD Multi / 15.5 inch / Windows 7 Home 32bit ⇒ Windows 10 64bit Pro (Free version) installed. (You can use it as is, but please install Windows 11 or your preferred edition later) Resolution: Full HD 1920 x 1080 Wired/Wireless LAN available, with speed switch. Equipped with a built-in custom SSD, it starts up just as quickly as modern laptops. USB 3.0 x 2 USB 2.0 x 1 HDMI output terminal D-Sub terminal available, allowing for expandability and mirroring to a large monitor. Since the SSD capacity is not large at approximately 120GB, connecting an external SSD, etc., will allow you to use it as a sub or even a main machine. * Although a long-duration operation test has been performed with the power cable, the battery is a consumable item and is not covered by the warranty. There are scratches, stains, and shine, but it has been cleaned and is ready to use immediately. Please refrain from purchasing if you prioritize a pristine condition. #SONY #VAIO #SSD #USB3.0 #SVS151A12N #FullyFunctional #Laptop #NotebookPC #Black #WhiteLED #SubMachine OS: Windows Series: VAIO CPU: Intel Core i5 Storage Type: SSD
