Welcome to the Dell Community  [NAME]  Install an Intel 6235. The BIOS may not see the Bluetooth part of the card but W10 will. I use the same card in the E6420 XFR with no problems. The only problem would be if you had the 380 installed. Best regards, U2 Note: When order using only Dell's part number. Dell DP/N 5K9GJ Intel Advanced-N 6235  
I read a topic here that mentioned something about some E6430s coming with bluetooth "disabled". Does anyone know the details of what this "factory bluetooth-disabled" thing is? This E6430 has a smartcard reader and a fingerprint scanner, so I suspect the original owner was pretty security-conscious. I want to add bluetooth to this E6430, but I don't want to just buy a 380 card and cable and tear it down to try and install it only to find that this is one of those machines that won't allow bluetooth even if I install the card. Or is there some other way I can tell if this E6430 has this "feature" or whatever you want to call it that prohibits bluetooth connectivity?  And would this anti-bluetooth feature, if it has it, keep me from using a bluetooth USB dongle?    
E6430 - Can I tell if adding a 380 bluetooth card will work from the original 
specs?
