Inspiron update : I found that the speakers attached to the docking station give a moderate hum when the main laptop power is disconnected from the docking station. The speakers are separately powered, and plugged into the headphone jack on the dock.

The hum gets louder when I unplug the network cable.


Getting a carrier hum thru speakers attached to the headphone jack ONLY when the power was not connected to the dock - plug in the power cable and the speakers go silent. Unplug the network cable (with the power not plugged in) and the hum gets louder. Grounding loop?

Replacing the Docking Station - see if that helps. Boots now, will revisit tomorrow.
