@NILAMBAR,
I reviewed your post and I understand that the night mode is not working after a recent Windows update and you are facing issues with the display.
Don’t worry, I assure you I will try my best to get this sorted.
I recommend you update the BIOS and the graphics driver from the below link and check whether the issue is resolved.

If you continue facing the issue, then install all the Windows updates (Including optional) and check.
Here is how it is done.
- Select the Start (Windows) button from the bottom-left corner.
- Go to settings (gear icon).
- Select the Update and Security icon.
- Choose Windows Update tab in the sidebar (Circular arrows)
- Select Check for updates. If there is an available update, it will begin downloading automatically.
Let me know how it goes and you have a great day!
