Notebook Video, Display and Touch

Hi all:

I hope that this is the right board for this problem, even though it may not be primarily a "Touch" issue.  My problem is that I keep losing my pointer/cursor on my HP laptop. Here are my specs and details of the problem based on a set of questions that I found on another thread:

What make / model computer? HP Pavilion 15-n216us

What operating system? Windows 10 64bit upgraded from Win 8.

Does the mouse left alone disappear or are you clicking on something and then it just disappears? It only (and always) happens when I touch the screen. The cursor disappears instantaneously when I touch the screen. It happens whether I have a USB mouse plugged in or not.

How do you normally resolve the issue? Except for restarting the laptop, the only way that I can get the cursor back is to go to Personalize/Themes/Mouse Pointer settings. I then have to close the Mouse Pointer settings windows (clicking OK) while shaking the mouse.

How is your mouse connected to your computer? Wireless but as stated above, it also happens when the mouse is not plugged in.

One screen or two screens? If one, have you ever used two? One screen, never two.

More information:
1) The cursor is not set to disappear when typing.
2) I read that this could be a problem with the Touchpad, so I downloaded the Synaptics Pointing Device driver for my laptop from the HP website. When I attempted to install it, I got a message that I already have a newer driver than the one I downloaded.

3) I have searched online for a solution to my problem for weeks but mainly find information about people totally losing their cursor when upgrading to Win 10.

4) I did have to reset this laptop once but the problem started months after the reset.

Any ideas as to what could be causing this problem and how to solve it?

Thanks,

Edwin
