I dd all this exactly as indicated and will reboot now. What I couldn't do is:

 

12.Execute steps 8-11 for 'Intel(R) Smart Sound Technology (Intel(R) SST). -> This driver never appeared in Sound, video and game controllers, as I've said a few times

 

14.Uninstall each the following devices in the same order.

a.Detection Verification -> there is no "Detection Verification" item in the "System Devices" category

I now rebooted, audio is not working and I clicked the link above but it is not a working link. Could you send the right link? Or should I use Lenovo Vantage to re-install the correct drivers?

Uninstall each the following devices in the same order.

a.Detection Verification -> there is no "Detection Verification" item in the "System Devices" category

 

This ias to say that verify the step 9 listed INFs and deleted successfully.
