Lenovo ideapad z500 brightness adjustment

2013-02-09, 19:08 PM

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

Solved! See the solution

hi shockwave3,


Can you try to apply the fix by s_roland on this thread (see page 2):




The solution was to:
1. Clean install Windows 7
2. After installing Windows, install the Intel Chipset Driver and reboot.
3. Install Lenovo Energy Management and reboot.

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

Is this answer? We don't have any data on laptop, we can re-install every day.
