Dell Precision 7540 drains the battery when USB-C

I have a Dell Precision 7540, which I connected to the 4K DisplayLink. With the USB-C connection I noticed that my battery drained down to virtually “0”. I had to remove and reset the battery to get the laptop to even boot up. As soon as I plug the USB-C into my Thunderbolt port, the drain starts (even with my power cable plugged into the laptop) and reaches 2% very quickly. I am then required to “reset” the battery. Without the USB-C plugged into my laptop it is “business as usual”. I like the docking station, but have simply had to quit using it in order to save my laptop battery. Help/thoughts?
