Lenovo Yoga Intel(R) BIOS update 2017-09 corrupted all "Fn" functions



I did a update to my Lenovo laptop vie a auto update request for intel(R) on the system yesterday.
And now i can't adjust Brightness or sound or anything for that matter, Vie the "Fn" selections.
The key is light but it is inert (as in nothing happens).
Fn + Esc Does'nt do anyting for the on and off function. It's like the driver for "Fn" is corrupted.
How can i revert back to an older version? Or can i reset the system to factory and get the old system?

PS: This is not an OS issue since i have dual boot and both have the same problem.
