What would cause my Boston Acoustics Docking Station to stop working during playback and now no longer powers up despite power adaptor functioning properly.

There should be a fuse in the back but it would only blow if the wiring is funny because the car's fuses are closer to the power supply and should go first, but try anyway

try universal power plug sold at any CVS or Wallgreen start from lowest voltage and go up till it works make sure the plug matches and polarity

These are supposed to be self-powered, so I don't think a power adaptor is needed. You may have a sound card issue. Also, check the master volume control on your computer. Is it a desktop or laptop? What brand? What os?

If the docking station has power:

Make sure power is off for both the laptop and the docking station. Plug your keyboard and mouse into the docking station. Dock the D630 to the docking station and then power on docking station. This should then turn on your D630. Your D630 should detect the keyboard and mouse.

If the docking station has no power:

Verify that the power cord, AC adaptor, etc. is plugged in. If the items listed seem to be in order,
there may be a problem with the power going into the docking station. (AC adaptor?)

support.dell.com will have the specific details for your D630 and your docking station, et al.

Please let me know if you have success in this.

I was having the same problem - the USB ports seemed to have stopped working so I could not use the mouse, keyboard, or printer, even though the monitors and power could still operate through the docking station. Finally, I just unplugged the docking station for 30 seconds, plugged it back in, and everything resumed working. I was surprised it was that simple, but it's working for the moment.

Have you tried other speakers? If so did they work? You might try updating the sound card drivers.
