13.3-inch laptop Vaio S Series PCG-4121GN VPCSB4AJ. This is a used Vaio from the Sony era. The specifications are as follows: OS: Windows 11 Home 25H2, Activated CPU: i5-2450M 2.50GHz Memory: 8GB SSD: 128GB DVD Multi Drive AC adapter included. The SSD has been replaced, so startup is relatively fast. It has been upgraded to Windows 11, but not all unique buttons and functions work. (WEB button and CD eject button worked) I was able to enter the BIOS menu by pressing the F2 button at startup. Battery maximum capacity is 41460/52170 mWh. There are no noticeable large scratches, stains, or damage on the main unit, but there is some wear and tear. Also, some of the rubber feet are missing. Please check the images. I have confirmed the connection of wireless LAN and wired LAN in my environment, but please consider it as junk due to its age. Series Name: Vaio Note Model Name: Vaio OS: Windows 11 Home CPU: Intel Core i5 Storage Type: SSD Storage Capacity: ~160GB Other Features: Junk
