Brightness Slider Gone from Power Plan

Hi,

Thank you for writing to Microsoft Community Forums.

Select action center/notification button on the right side of the taskbar, and then move the
Brightness slider to adjust the brightness. As mentioned in the article, if you
don't have a desktop PC and the slider doesn't appear or work, try updating the display driver.
As you have already update the Display drivers, I would suggest you to uninstall and delete the drivers then update it again. To uninstall and delete the drivers, please follow the steps mentioned below:

1. Open Device Manager and then expand the Display adapters
   section.
2. Then right click on options listed below and click on Uninstall.
   
3. Check the box next to Delete this drivers.
4. Then reboot your device and update the drivers. You can also try updating the Batteries drivers along with display drivers from manufacturer’s website.
   

Regards,
