Bluetooth chip adapter missing in device manager.
Is your Bluetooth chip adapter going missing from the device manager? Here's our expert's advice on what you can do about it.
I have an Acer 5749 laptop. My bluetooth is working fine with Windows 8.1. When I upgraded to window 10 it was working right but after some time my pc hangs with a blue screen and there is no display in the screen.To resolve this issue I have put out my battery and fit it again but after that there is no bluetooth adapter I could find in the device manager.I tried my best to resolve this issue but no result. Even I went to the pc shop but I was told that my bluetooth adapter is damaged. Any solution for this problem? My adapter chip is atheros - ar5bbu22.
