Windows 10: Display brightness is reset to 50% whenever I restart my laptop - Windows 10 Version 1809

Hi all


After updating to Windows 10 Version 1809 on my Lenovo laptop, the display brightness is always reset to 50% whenever I restart the laptop. By the way, the brightness setting which should locate at the bottom of the Control Panel is gone. The screenshots are attached below. I tried updating the Intel graphics driver and the NVIDIA graphics driver but this did not work.


Thanks

:)

 

Unable to Change Screen Brightness of Laptop


So I'm not sure how long this has been happening but for some reason, I can't change the brightness on my laptop screen. I have linked a picture and as you can see, my brightness says 0% and that I can't change it, however my actual brightness is at 100%. I have looked around everywhere and the only responses I have found don't work for me. Here's a list of everything I have tried:
- Reinstalling Display Drivers
- Rolling Back Display Drivers
- Reset Settings on UWT4
- Power and Battery Settings
(UWT4 or Ultimate Windows Tweaker 4 is a customizer for Windows 10 and I thought that might be the problem but it wasn't)

If anyone has any suggestions on how to fix this, it's greatly appreciated! Thanks! -

 

Can not control the laptop brightness

Hi Dinh,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing currently.

I would appreciate if you can provide us the following information to help us understand the issue better.

What happens when you try to change the screen's brightness?

For a majority of laptops, there isn't a control for setting the contrast. However, you can set the brightness of many laptops by pressing and holding the Fn key, and then pressing a function key to decrease brightness
or increase brightness.

I suggest you to uninstall the display driver from your computer and then install in Compatibility mode.

To uninstall the driver follow the steps given below.

• 
  Press Windows key + X and select
  Device Manager.
  
• 
  Search for Display Adapter
  and expand it.
  
• 
  Right click on the Display Adapter
  and select Uninstall.
  
• 
  Do not restart your computer.
  

Once you have successfully uninstalled the driver, please install the driver in compatibility mode following the steps given below.

Make older programs compatible with this version of Windows
