In order for everything to work, including an external monitor if necessary, a Thunderbolt 3 connection (plug analogous to USB 3 Type-C) must be available. The Lenovo Yoga actually has this. But to be on the safe side, check it.
Still looking for a docking station for my Yoga 720-13IKBR. Does this dock work correctly now? Also HDMI? With my current docking station it only recognises the monitor every 10th time. Another question: Can I switch on the device via the dock, or do I have to open the laptop?
