Touchpad not scrolling after setting ScrollControl_Mode to 1

Hi Silver Phung，

Welcome to Microsoft Community

The issue you're facing with your laptop's touchpad not scrolling after setting ScrollControl_Mode to 1 seems to be a complex one, but I can suggest a few steps that might help in resolving it. Let's break it down:

Immediate Steps to Try

1. Revert the Setting Change:
   
   • Since the problem started after changing the ScrollControl_Mode to 1, the first step would be to revert it back to its original setting (probably 0). You mentioned trying this without success, but ensure that the change is correctly applied and saved.
     
2. Update or Reinstall Touchpad Drivers:
   
   • You’ve already checked for driver updates, but it might be helpful to completely uninstall and then reinstall the touchpad driver. Sometimes, simply updating doesn't fix issues that a fresh install might resolve.
     
   • Go to Device Manager, find the touchpad (possibly under "Mice and other pointing devices"), right-click, and select "Uninstall device." Then, restart your laptop and Windows should automatically reinstall the driver.
     
3. Check for Windows Updates:
   
   • Occasionally, such issues are resolved through Windows updates. Ensure your system is fully updated.
     

Dealing with ELAN Touchpad Issues

• ELAN Tab Missing:
  
  • If the ELAN tab in your mouse settings is not showing up, it suggests a deeper issue with the touchpad driver or configuration.
    
  • Try downloading the touchpad driver specifically for your model from the Lenovo support website. Ensure it matches your exact laptop model and Windows 11 version.
    
• ETD Properties App:
  
  • The error message from the ETD Properties app indicates a disconnect or incompatibility with the ELAN driver. This again points towards a need for a driver reinstallation or update.
    
  • Make sure you’re downloading the right version of the app compatible with your Windows 11 version.
