M6500

Hellos - I have several old units running XP. I need them to run old imaging systems that have no updated drivers. I have 3 that I use; M6500, M4500, D830.

On my M6500 the bluetooth is very oddly setup. It seems to be set in the WPAN card, but I am not 100% sure. I have read that there my be a BT card under the LCD bezel??

anyway, I cant get the BT to work. While the WPAN card is installed, in the BIOS it shows 'NONE' in systems devices. Yet I have a BT light on the panel on above the keyboard. I cant hook any BT devise [no discovery].

I have tried 2 WPAN cards.

How do I get it to work?  TY  regards,, dw
