Originally, this was a 16GB memory, 512GB SSD model, but it has been upgraded to 8GB memory and 256GB SSD. The memory is Hynix, and the SSD is believed to be Micron, but please confirm with the product images and model numbers. The memory has been confirmed to have no errors in memtest, as shown in the image. Windows 11 Pro license has been activated. The BIOS has been updated to what is believed to be the latest version at the time of listing. The OS will be initialized upon shipment, but please note that you will likely not be able to connect to the internet via Wi-Fi as is. The OS has been reinstalled with a clean Windows 11 Pro downloaded from Microsoft's official website. The OS image does not include drivers for the Wi-Fi AX201, so you will need to download them via wired LAN or a USB memory stick to connect to the internet. (A driver pack is available on the manufacturer's website forum) Also, the driver for the Intel Serial IO GPIO Host Controller - INTC1057 chipset is not installed via Windows Update and needs to be manually installed from the Microsoft Update Catalog or the manufacturer's driver pack. (This seems to be common when installing a clean Windows on models using the N100, but it seems to work normally even without installing it) Due to the above specifications, it may be difficult to set up for the first time unless you are able to install the OS yourself. Please note that we cannot provide after-sales support.
