Hi Katherine Scalaro
I agree that on some laptops I worked with, it seems there is a "touchpad / trackpad disease" auto scroll or etc.
Some workaround I do for my friends, etc…
Consider updating your computer BIOS too.
1. Update the trackpad drivers and monitor if it helps.
2.Disable trackpad / touchpad if using mouse.

3. Replacing the module, (can be very difficult) some are glued securely to the laptop frame. (IMO I will just live with it and just disable the trackpad as on No 2., using mouse)
