I have a Microsoft Surface Pro- about three years old. I also have a docking station - about two years old, but not used that often. The docking station appears to be charging the Surface just fine, but none of the ports appear to be working - not the USBs, not the extended display, nothing. I have updated the drivers and unplugged the docking station and then re-plugged it in, but the mouse, keyboard, and the monitor are not recognized at all. I am pretty upset about this because both the Surface Pro and the docking station ($200 for the docking station!) were a lot of money and I don't feel like the docking station should be failing when I have used it maybe half a dozen times. I use the Surface Pro daily.
