Re: Dell D600 BlueTooth is not working after Bios upgrade
The bluetooth module on your D600 has come loose internally. I'm the IT Manager within our Comapny and we have had 8 X D600's with this problem which have had to have motherboards and bluetooth modules replaced.
The system keeps flashing up the message "USB device not working properly". It seems that the bluetooth module is not very securely held on to the motherboard and it can work itself loose.
Hope you've managed to get it sorted.
