Hey all,
I would like to post my recent version of the .ahk scipt here, since I've introduced a small update. It includes the capability to toggle and keep the backlight setting during the OS session. there is also has a .bat inlcuded, which kills the tposd.exe service which handles pop ups while changing backlight level (which is done automatically).
The HotKey is set to [Ctrl]+ [Space] which toggels between level 0, 1 and 2 of the backlight.

; To deactivate "Lenovo OnScreenDisplay Service" (status display for backlight keyboard, microphone, Fn lock) prevent execution of "C:\Program Files\Lenovo\HOTKEY\tposd.exe"

global BACKLIGHT_LEVEL := 2 ; set to 0 for no backlight, 1 for the first (dim level), 2 for the brightest level
global IDLE_DURATION := 20000 ; after how many milliseconds of inactivity the light should turn off
global POLLING_PERIOD := 1000 ; how often (ms) should the program check for inactivity; lower turns backlight on faster but drains cpu
