Do not use with new Dell 7520 or7720 laptops
2 of 3 found this helpful Even though Dell sales says this doc will work with new Dell 7720 or7520 laptops it really does not.
Two of the three monitor outputs are disabled so no dual screen available. Also it is 230 watt power brick the new laptops require 280 watts or it will not charge the battery. If you use it with the outdated Dell E model laptops it is fine.
