Recently, I've bought the Lenovo Pro Dock docking station. This one requires 90w to function according to the official Lenovo website. However, my Thinkpad P51 doesn't charge when plugged into the docking station connected to the included 90w adapter.

My laptop does charge with the 170w adapter plugged into the docking station. Is this a problem, since it's connected to a 90w docking station? Can it do any harm?

I don't want to ruin my (expensive) Lenovo Thinkpad P51.

Many thanks in advance!
