What is this & why is this happening?

Dear forum members my laptop Lenovo V330, running on Windows 11, is showing a peculiar behaviour since last month. The screen starts to scroll all by itself as if some demonic forces have taken control of it. It doesn’t have any external/3rd party applications installed. I have tried various solutions mentioned below to sort out the issue but it still persists. My last resort is approaching the skilled members of this forum for help & suggestions.

  1. Checked all the keyboard keys for proper working or if any is stuck.
  2. Used a blower to blow away / dislodge any dust particles etc stuck between the keys.
  3. Used an external keyboard
  4. Formatted and re-installed Windows 10 & Windows 11.
  5. Have uninstalled MS Office so no software application is installed.
  6. Even uninstalled the last Windows update.

Laptop configuration is

CPU: Intel Core i5 8250U

SSD: 256 GB

RAM: 12 GB

Mouse issue. First disconnect any external mice bt/2.4/usb and check.

If not solved then go to device manager - Mouse - Uninstall.

It’ll be Auto reinstalled anyway but you can test if autoscrolling has stopped and proceed from there

No external mouse or monitor is installed. Still on your advice I will uninstall the in-built mouse from the Device Manger. Attaching screenshot of the same.

I’ve fixed this issue on someone’s laptop before. It was due to one of mouse or keyboard drivers.

I found the solution on reddit but don’t remember which. Look up auto scroll issue reddit

As per your advice I have uninstalled the internal mouse’s drivers and connected an external mouse. Let’s wait and watch
