It is assumed you have the Lenovo Power Management driver installed.

  1. Install AutoHotkey. I recommend choosing the advanced installation option and enabling the UIAccess option (be aware, however, this option adds a self-signed cert to the store). This will allow the script if non-elevated to send the media keypresses even if the foreground window belongs to an elevated/UIAccess program.

  2. Using regedit, export/BACKUP! HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\ShortcutKey\AppLaunch somewhere.

  3. Run this script as admin once so that it can add Registry entries to stop the Lenovo hotkey software from performing the original actions on Fn+F9,10,F11,F12. (NOTE: This may have to be repeated every time the Lenovo Hotkey software is upgraded)

  4. Hit Win+R, run shell:startup and drop the script in there. If you have installed AHK with UIAccess support, the script will automatially relaunch itself accordingly.

Do Step 2 and backup that key mentioned; this script will stop the original key functions of Fn + F9 to F12.
