After my laptop comes back from sleep it loses its ability to change brightness

I noticed this happening a few days ago. I am working on a 5 day old Lenovo c930 yoga with i7 - 8550u with intel 620 UHD graphics. I have been manually going into device manager and disabling > enabling the intel 620 Display adapter to get the function back. I am fully up to date with my drivers.
