Lenovo G575, after Windows 8 upgrade brightness will not change

Hi thanks for your help in advance.

 

After I installed Windows 8, my brightness has been stuck at almost minimum.  The hotkeys no longer work, and neither does chanching the brightness in the power settings.

 

I've tried updating the drivers for my display, as well as re-installing the Windows 8 Lenovo Energy Management to no avail.

 

Any help would be appreciated.

I have the similar issue but my P500 came with windows 8 and after watching a movie on a dimmed brightness, it wont come back... neither the hotkeys or the power settings do anything.
