First if all we all know the bluetooth is not allowed in FLL games. But, FLLers can certainly utilize it for NXT programming training, etc.
Like Eric, I haven't use the NXT bluetooth with a laptop bluetooth (built-in or added-on). However I have troubleshoot the installation issue on Microsoft Window bluetooth when I tried to use the bluetooth on the cellphone transfer the photos to a laptop with a bluetooth dongle so I think I can offer a suggestion - Try pair a cellphone with the laptop. If it doesn't work the problem is most likely on the laptop. If the problem stays after you reinstall the bluetooth software, you may need to clean up "hidden/inactivative device" in Device Manger adn then reinstall the driver. the How-to is here - http://www.tech-recipes.com/rx/811/xp_vista_remove_hidden_devices/
