Toshiba dynabook B55/B Laptop, 17.3 inch - Model Name: dynabook B55/B - Brand: TOSHIBA - Screen Size: 17.3 inches - OS: Windows 11 - 8GB Memory - 200GB Capacity - SATA SSD Installed - Wired LAN / USB Ports Available - Adapter Included ※ This is a used item, and due to battery degradation, it cannot charge and operate without being connected to the adapter. It functions normally when connected to the adapter. However, it is recommended to replace the internal battery if possible. Other than that, it runs smoothly. It connects to Wi-Fi and other networks easily. ※ While many similar products seem to be 15.6 inches, measuring the diagonal reveals it to be about 44 centimeters, suggesting it is a 17.3-inch model. ※ I am not very knowledgeable about PCs, so I took the necessary pictures while researching online and interpreted the information from them. I cannot answer detailed technical questions, so please judge the information based on the images. Thank you for viewing.
