Pros: Dock is 100% Compatible with 540. Works fine
Cons: Charger is too small for W540. W540 needs a 170 watt 20V 8A charger, which comes with the computer and has to be ordered separately for yet another charge. Although New Egg shows it in their inventory, the charger can only be purchased from CHINA. 2 week wait.
Overall Review: Very nice dock, wish that Lenovo put some thought into true compatibility.
