Moving cursor on touch pad

[Sshanker]

Notebook bought last month. The cursor moves on its own down the screen.

BIOS was changed a few days ago. The driver was updated a few days ago, so it's the latest.  But the problem continues, although it did get better with the cursor not "running away" so often.  Restarting the notebook hasn't helped.

The tests from an HP diagnostics tool show that all is OK. There is nothing on the touchpad for the cursor to move like this.  Apparently, HP customer service reps don't really know what is going on, and the last experience I had was an hour wasted for the second time.  So, if anybody has an idea of what this issue could be, please post.  

Thanks in advance

I did that and the problem persists.  I also removed any other movements I can do with the touchpad and the problem persists to the point that just this morning I was able to capture the issue live on my iPhone.
