Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers. It would be my pleasure to assist you with this. Let's begin with your wife's computer since that is probably going to be the easiest problem to solve. Can you tell me the exact model for her computer please and also, let me know what operating system she has on her computer?
Here's how to Disable your Touchpad via the BIOS. This should work for all Thinkpads.
Note: If you are unsure of what Fn key to press when the ThinkPad is booting, try pressing Enter button and select the bios from there.
Please give this a try and let me know how it works for you. If this solves the problem, would you mind taking a moment to rate my service? I'd really appreciate it! Without a rating I am not credited for my answer. If this doesn't solve the problem be sure to let me know so we can continue troubleshooting.
