I upgraded the SSD in my Y740. Did a fresh install, did all the windows updates, did all the updates from Lenovo's site. Can't figure out why the function keys no longer show OSD. FN+F11 - trackpad. Trackpad enable/disable works, but not OSD. FN+F10. Webcam - No OSD, does NOT disable/enable webcam. FN+Q - Power modes. Power modes cycle, but does NOT show OSD. There might be more, but you get the idea. Anyone have any idea on what piece of software I'm missing? I've basically got them all from Lenovo's site, from what I can tell.
