New docks will also come with a USB adapter lead that will allow them to work with the old style laptops that don’t have the smaller USB-C port. To use this adapter you will have to plug the USB-C connection into the adapter as shown below.
Once connected for the first time the laptop will then go through installing software automatically which allows it to work with the new docking station. This may take up to 10 minutes. During this time your external monitors and Ethernet connection may not work.
This USB connection will not charge your laptop. Instead, you will need to charge your laptop with the normal portable charger pack.
