Windows 8 Problem re: screen brightness adjustment

Troubleshooting Steps:​

1. Restart Your Laptop: Start by performing a simple restart to see if that helps reset the settings.
2. Update Graphics Drivers: Outdated or corrupted graphics drivers can sometimes cause display-related issues. Try updating your graphics drivers to the latest version.
3. Use Function Keys to Adjust Brightness: Instead of the graphical scale, try using the function keys on your keyboard to adjust the brightness levels. Typically, there are specific keys on Lenovo laptops for adjusting brightness.
4. Adjust Brightness in Display Settings: You can also try adjusting the brightness directly from the Windows display settings:
   • Right-click on the desktop and select "Display settings."
   • Under "Brightness and color," adjust the brightness slider.
   []Check Advanced Power Settings: Make sure that the power plan you are using hasn't set a specific brightness level. You can check the advanced power settings to adjust this:
   • Go to Control Panel > Power Options > Change plan settings > Change advanced power settings.
   • Look for an option related to display brightness.
   []Reset Power Plans: If changing the power settings didn't work, try resetting the power plans to their default settings:
   • Open Command Prompt as an administrator.
   • Run the command: powercfg -restoredefaultschemes.
5. Check for System Updates: Ensure your system is up to date with the latest Windows updates and Lenovo driver updates. Regarding your assumption about deleting settings folders, it's not recommended to delete system files manually as it may cause unforeseen issues. If you believe a specific setting is causing the problem, it's better to reset or adjust it through the appropriate system settings.
