No power to the plugable multi display docking station, HELP!

I work from home and about half way through my work day I lost complete power to the docking station. I have tried unplugging it and plugging it back in. I have plugged it into the wall, the surge protector, nothing is working. I know that there is nothing wrong with the power to that outlet because I have two monitors plugged into the surge protector which is plugged into the wall, and those all have power to them. Is anyone able to assist?
