Welcome to the Dell Community  [NAME] 3  Do not try to install the Bluetooth card from the factory. Just remove the WiFi card installed and replace it with an Intel 6235. Is the card installed an Intel 6205? After the 6235 is installed the Bluetooth part of the combo card will not be seen in the BIOS. But W10 will see it and apply all drivers and updates. Let me know if you have any questions about the E6420 XFR. [IMAGE] I have refurbished hundreds of them. Best regards, U2
I've found a couple threads about this but not a definitive answer. Want to add Bluetooth to a 6420 XFR that was not so equipped from factory.  One thread mentioned a combo WiFi card was needed but I've found no source or part number for such a card. But there are standalone Bluetooth cards/cables listed for this model and advertised as pulled from a working 6420 XFR. My questions are - does this model actually require a special WLAN combo card (?) or does the (advertised/pictured) standalone card work. If the pictured card will work, where does it install? The service manual makes no mention of location in the machine. Seems I read somewhere it's under the palm rest. (?)   [IMAGE]
