:) :) :P after updating to the lastest drivers for nvidia geforce 8400m gs in vista x86 (177.92)

the fn+f8 and fn+f7 keys to decrease and increase the screen illumination doesn't work

is that driver related and if so is there a fix for it

I think its to do with smartdimmer being enabled in the drivers.

Its a known issue that having smart dimmer enabled can disable FN brightness on certain laptops.

To remove smartdimmer you need to modify the modded INF.

REMOVE:

under [Mobile_Tweaks]

HKR,, EnableBrightnessControl,[tab][/tab]   %REG_DWORD%,	1

under [nv_ControlPanelSettings]

HKLM,"SOFTWARE\NVIDIA Corporation\Global\NVTweak", SmartDimmerConfig,[tab][/tab][tab][/tab][tab][/tab]   %REG_DWORD%, 2
HKLM,"SOFTWARE\NVIDIA Corporation\Global\NVTweak", SmartDimmerEnable,[tab][/tab][tab][/tab][tab][/tab]   %REG_DWORD%, 1

CHANGE

under [nv_ControlPanelSettings]

;HKLM,"SOFTWARE\NVIDIA Corporation\Global\NVTweak", NvCplDisableSmartDimmerPage,[tab][/tab]   %REG_DWORD%, 0

to:

;HKLM,"SOFTWARE\NVIDIA Corporation\Global\NVTweak", NvCplDisableSmartDimmerPage,[tab][/tab]   %REG_DWORD%, 1

reinstall driver and see if it helps you
