Yes, but it disable both WLAN and Bluetooth. And I need WLAN.
Just now I found it! There is program called "ThinkVantage Access Connections". There You can turn off Bluetooth radio.
First, I am glad you found a fix. Second - There is something wrong, I think. Fn-F5 allows you to select either Bluetooth or WLAN. I turned my BT on and off (not using), while my WLAN was on and I was posting my prior post.
Take a look at the Lenovo support site for your model and look for appropriate drivers (Hotkey, Blue Tooth, etc). .... JDH
