Thank you for viewing. (Please note that this item has some important points. Please read to the end.) Model Number: CF-SZ5ADYMS CPU: Intel Core i5-6300U Internal SSD: 250GB Memory: 8GB OS: Windows 11 Purchased used in December 2021 and used for over 3 years, then stored indoors. As of April 2025, I have confirmed that it works with Windows 11 and connects to WiFi. Regarding the internal SSD, it was replaced with a new SSD when purchased as a used item in December 2021. Important points: ・As shown in the photos, there are several places where the paint is peeling off on the top cover and elsewhere. ・If the AC adapter is inserted at a slightly skewed angle, charging may occasionally fail. In such cases, adjusting the angle by hand will allow it to charge normally, but it's not necessary to hold it in place continuously. As this is a used item, please consider purchasing it if you understand the above points.
