I am able to adjust the screen brightness and volume however the indicator of the volume and brightness are missing on the screen.


The on screen display features may vary by model of system and generally have dependencies on the hot key drivers, Lenovo power management drivers, and display drivers.


If this feature has stopped working after a Windows update or after re-loading a fresh copy of Windows, we recommend downloading and installing the latest hot key, video, and power management drivers for your particular system model.  These files can be found on the Lenovo support site.
