The specifications says that the system comes with USB-C port and built-in Wi-Fi. It does not have a USB-C port, instead, in that space, I have a serial port, which is useless. No peripherals use serial ports anymore. Instead of the built-in Wi-Fi it has a cheap Chinese knock off USB Wi-Fi that will not connect to any network. I was able to use a USB WiFi adapter from a raspberry pi to get online. As a result, not only do I lose the USB-C port, I lose one of the other ports in order to support Wi-Fi. The bundled mouse is completely unfunctional: it just swings the cursor wildly around the screen with no relationship to my actual hand motions. Pretty lazy “refurbishment“ if you ask me. I can’t waste time returning this, however. The system has to get put into production. Thought I could trust an “Amazon certified” refurbishment, but apparently not.
