    I can't change laptop screen brightness - Intel GM45, Windows XP


      I can't change laptop screen brightness in any way - by buttons Fn+F7/F8 or through the driver.
      Other Fn buttons (ex. Fn+F3 => WWW) work correctly (HP Quick Launch Buttons installed successfully).
      This trouble is observed only in Windows XP. In Windows 7 the buttons Fn+F7/F8 change brightness.

      All other drivers were installed correctly.
      I think it is problem of Intel Graphics Driver for Windows XP.
