Thank you for viewing. This is a dynabook laptop equipped with an Intel Core i5 processor. It was purchased over 10 years ago and had been unused for several years, but when I started it up, it surprisingly ran normally, so I decided to initialize it and put it up for sale. However, it is still a very old item, and the OS support has ended, so please be aware of that. Also, the battery is quite worn. Please consider using it while plugged into a power source. In addition, the results of the operation check are as follows. Both Windows 7 and the IE browser are no longer supported, making internet connection generally difficult. It seems unusable in some cases, such as when you need to update software via the internet even for offline work. ◯ Operation Check Results ・Browser The initial browser, IE, is no longer supported and unusable. Even when I tried to install Firefox from another PC, a message appeared saying it couldn't be installed on Windows 7, making it difficult to browse websites. ・Optical Drive When I tried playing CDs and BDs, CDs played without any problems. BDs are also being read and displayed on the My Computer screen, but there is no corresponding player. I think it's probably possible if you install a player separately, but I haven't confirmed the operation, so I can't guarantee it. ◯ Brand: dynabook ◯ Processor: Intel Core i5 ◯ OS: Windows 7 ◯ Memory: 4GB ◯ HDD Capacity: 600GB ◯ USB Ports: 2 on the right, 1 on the left ◯ Blu-ray drive installed ◯ Display: 15.6-inch wide (16:9)
