inactive wifi button

[dombo]

Hello All,
I need some expert advice.
I had an issue with turning on WiFi. I have only software button and not any hardware ones. Bios - checked, restarted in safemode, drivers - reinstalled and the wifi does not giving me an errors in tests but still on/off button is innactive and I can not use the pc. It do not have lan as well. Laptop: Lenovo Yoga 2, windows 8.1 distributed with the laptop
I was looking for how to force the wifi on through the registry but did not manage.
Does anybody have an idea what to change and how to make the button active?
Thanks in advance for your ideas!!!

I suggest you go into Device Manager to see if wifi has been disabled, or if there is an error triangle next to the listing for the wifi device.

If it is enabled and had an error triangle, uninstall and reinstall the driver.

Thanks for the idea but it is already checked before posting the issue and on the picture you can see the device manager.

The unknown part is something with the audio but nothing related to the wifi.

I checked all the possible methods before writing

If somebody knows where to force the turn on sets in the registry it will be welcome
