Hi all Back about a year ago my built in Bluetooth stopped working. Does not show up any longer. I tried replacing module on motherboard with another, still nothing. So, my question after reading some threads, could a system update have made it unusable? Never wanted to take it to have repaired or diagnosed because I had assumed that somehow motherboard repair or replacement would have been needed. Which leads me too this To upgrade to new combo card would require using the plug where current Bluetooth module is plugged in. Which would possibly never work because of my problem, if hardware related. ???? thanks in advance for any help or ideas.
