Re: Cursor jumping all over while typing on keyboard
Welcome to the Community. I suggest you first uninstall the existing driver and reinstall the touchpad driver using the below link. To uninstall click on start, right click on computer, click on properties, click on device manager, click on on the symbol next to pointing devices, right click on Alps touchpad, click on uninstall, click ok to confirm. Once its removed, do not restart your computer, use the below link to download and install the driver. Restart your computer.
You can also try changing the sensitivity. Click on start, control panel, mouse, click on the touchpad image, and reduce the sensitivity to see if that makes a difference.
