This is a dynabook T553/37JG laptop with a Japanese keyboard layout. Please note that the OS is Linux Mint, not Windows, before purchasing. - Brand: dynabook - Model: T553/37JG - OS: Linux Mint 22.1 - Processor: Intel Celeron CPU847 1.1GHz x 2 - Memory: 3.7GiB - HDD: 751.2GB - Display: 15.6-inch wide (16:9) HD TFT color Clear SuperView LED LCD (power-saving LED backlight) 1,366 x 768 dots - Blu-ray Disc Drive - Keyboard: Japanese layout - Touchpad: Yes 【About OS and Performance】 Linux Mint has been installed because the original performance was slow. I was considering using it as a dedicated Zoom machine, but it seems a bit difficult. The speakers, microphone, and camera are recognized. It might be possible to use it more comfortably by upgrading the memory or replacing the HDD with an SSD. Please note that the current OS is not Windows. 【Included Items】 - Main unit - Power cord - Mouse 【Appearance】 There are noticeable scratches on the top cover, and there is a general feeling of use.
