Thank you for viewing. This is a Linux OS-equipped laptop. Originally, it had Windows installed, but due to an error, it couldn't be initialized, so I had to reluctantly install Linux OS and am now listing it for sale. The Linux OS works without any particular problems and can be used normally. Wireless WiFi (dongle) is also available separately, allowing you to use both wireless and wired connections! The keyboard has only been used about twice and is in excellent condition. The mouse also has few scratches and both can be used! The Linux OS feels almost the same as Windows, and you can use applications like Zoom, watch videos, and surf the internet. Included: PC (main unit) Battery (charger) Keyboard Mouse Wired LAN cable (bonus) SSD: 128GB CPU: core i3 Memory: 4GB
