Since update to Windows build 14986 (slow ring) brightness Fn keys not working and there are only 3 levels on brightness in settings:
I think it is similar topic as this https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Yoga-OLED-brightness-issues/td-p/3419994
I reinstalled the graphic drivers, reverted, updated. Reinstalled Lenovo apps.
Can you update the Intel driver?
Also about Lenovo settings app. Battery meter when it is clicked nothing is showing as it was before.

Thanks for using the Lenovo forums.
Try to see if you can use the following software to update any drivers.
Make sure to reboot after an update.
Hope this helps, let us know how you get on.

Still not working.
This tool want to update chipset driver to older version.
What worries me, that in Device manager I have 'Standard PNP monitor'. Should be there something else like QHD Yoga monitor?
