Re: Dell D600 BlueTooth is not working after Bios upgrade
If you still have had no luck, the problem sounds like hardware. Windows sees Blue-tooth as a USB device, hence the messages. The other tip-off is the device not always showing up in Bios. The blue light often goes on and off ( another sign ). If under warranty I would place a service call. If not you may be able to fix it, or apply a work-around. The Bios is out of the OS, so the fault may be unrelated to the reload.
