I have a lenovo laptop in which the cursor jumps if i type speed it get like (deeps) why is it wo?

I am not understanding what your question is. From what I could make out of your post, is that it seems to be maybe the users fault. Potentially, while typing you could lift your hands up..?

I'm not sure if this is answering the question just because I don't understand it. More details and be more clearer if possible.
