Compatibility
Lenovo says the dock works with notebooks that support Thunderbolt or USB-C Alt Mode through their Type-C port, including select ThinkPad, Lenovo and non-Lenovo systems running Windows 10 or later. MAC address pass-through, Wake-on-LAN and the mirrored power button are supported on most ThinkPad notebooks but may not work on other brands, and Intel AMT is supported only on select 11th Gen Intel Core vPro PCs.
Who it's for
- Suited to: offices and hybrid workers with Thunderbolt 4, Thunderbolt 3, USB4 or USB-C Windows laptops who want multiple monitors and wired networking from one cable.
- Not suited to: laptops whose USB-C port doesn't support Thunderbolt or DisplayPort Alt Mode, or anyone who only needs a simpler USB-C hub; the ThinkPad USB-C Dock Gen 2 is an alternative.
