Hi, I bought new z500 ideapad and funkcion buttons f11,f12 are not working to adjust brightness. I reinstall both Nvidia and intel drivers, also uninstall/install power management but useless. Function keys are working only when OS Windows 7 is starting, when OS is running fukction keys are without response. I also change register key , changed from value 1 to 0, also useless. Any other help or advice? Thank you

Can you try to apply the fix by s_roland on this thread (see page 2):
4. Install Intel Video Drive for Windows 7 64bit and reboot.
5. Pressing Fn+ F11/F12 to toggle the brightness should now work.
Hope this helps
