Hello Lawrence Guillory,
Welcome to Microsoft Community.
From your description of the problem, it appears that you have contacted Microsoft support through other channels?
After fully reading everything you've posted here, allow me to give some of my thoughts.
If you notice that the mouse pointer automatically moves in a certain direction when you are not doing anything, you need to first identify what is causing the problem:
- The touchpad of the keyboard is faulty.
- The touch screen of the Surface Pro 9 is subject to interference, such as electromagnetic interference or heat interference.
- Impact of third-party software.
If you currently find that the keyboard is not recognized by your Surface, remove the keyboard first, and then check to see if the mouse pointer automatically moves. If you notice that the mouse pointer is completely controlled by you, then this means that the problem is from the keyboard, but if you notice that the mouse cursor is moving automatically again, this means that although your keyboard is faulty, the problem is not caused by the keyboard.
Therefore, continue the troubleshooting process and try to determine whether the problem is from third-party software or whether the touch screen is being interfered with. I recommend trying a clean boot which starts Windows with a minimal set of drivers and startup programs. It can be used to determine whether a background service or program is interfering or causing a problem.
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step.
After Clean Boot is executed, the device does not load any third-party startup items during startup. In this case, check whether the mouse moves automatically.
If the problem persists, it's probably coming from the screen. Make sure there is no potential electromagnetic interference around your Surface Pro 9, and if there is a heat source, put it in a different location if necessary, and keep it ventilated.
However, we can't directly disable the touch function of the touchscreen at this time because you can't use the keyboard at this time, so I think the most authentic way is to send your Surface along with the keyboard to the Surface technical support team for a complete inspection.
I can direct you to Surface Live support, who can help you create a service order:
- Use your personal Microsoft account (not your organization account) to access the following links:
- Type Surface, press Enter, and click "Contact Support" at the bottom:
- Select Technical Support and select the device model you are currently using in Produce family, then click Confirm:
- You will see contact options for Chat support and Phone support, please contact them during business hours:
I wish you all the best.
