RE: Bluetooth adapter missing after upgrade to windows 10 BUT OS claims a new driver is installed!
You are correct. it is a "card" that is connected to the card that seems to be the audio port card. The manual would require me to disassemble the entire unit. Plus as I am in the Philippines, that cheap ebay offer will not be as economical for me. Still I may, with your suggestion have a way forward, it I want to hire a competent tech to change out the chip, assuming I can find one.
Thanks for your suggesting. I am not sure I want to mark this as answered, as I would like to identify the actual driver in the "device drivers" that is loaded now.
