Problem with touchpad and wireless mouse on a Fujitsu Lifebook

I was working on my Fujitsu Lifebook when I started noticing that the touchpad was not working properly. It started to lag, and the situation didn´t improve after restart. I tried plugging in my parent´s wireless mouse, but the computer does not even detect it. I am unsure what to do. What could the problem be? Is there a correlation between the two?
