Hi Tom,
Experiencing erratic movements of the cursor could be related to a hardware or driver issue, a third party software, or could be caused by a corrupted program. To help us determine what may have caused this, I would like to ask the following information:
- Were there any updates installed or changes made on your laptop prior to the issue?
- If yes, what were those updates or changes?
- Are you using an external mouse or just the touchpad?
While waiting for your response, please try the following steps:
Update Touchpad driver
- Right-click the Windows key and select Device Manager.
- Expand the Mice and other point devices category, right-click the touchpad, and click Update Driver.
- Select Search automatically for updated driver software.
- Follow the on-screen instructions.
Adjust Touchpad sensitivity
- Navigate to Settings > Devices > Touchpad.
- Adjust the Touchpad sensitivity to Low sensitivity.
If you have additional questions, or if the issue persists after the troubleshooting steps above, please let me know by replying to this thread. This way, I'll get notified and respond back to you as soon as I can.
Regards.
