Bluetooth Works in the Office but not at Home

I’ve installed 11.3 in a dual boot with Win7. I have a Dell M90 notebook. In both my office and my home I dock to an advanced port replicator. At the office the bluetooth adapter is seen fine by the system and the HP bluetooth mouse works fine. At home the adapter is not seen even though the hardware indicator is lit. Bios says bluetooth is enabled. If I undock at home the bluetooth adapter is still not seen.

Why would the same hardware behave so differently in two locations. Its like a bad Windows profile nightmare. Any help would be appreciated. BTW, the mouse works fine in Windows wherever I try.
