HP Spectre x 360 Convertible 15bl1xx Keyboard / Cursor / Tracking issues

[Layup]

When I'm typing the cursor will jump to some random area of the field in which I'm typing.  Doesn't matter which application I'm using - outlook, word, websites, gmail.  I've had HP support help twice.  First time they accessed my laptop remotely and fussed around.  Seemed to help a little but didn't cure.  After that they assisted me in removing the operating system and all software apps and then re-installed.  They said that if that didn't solve the problem I'd need to send the laptop to HP for assessment.  It did not help.  Before I take that step I'm hoping someone in the community may have a recommendation.

There have never been any related error messages.  Frequency of issue is random, but occurs often.  Usually within 5 or 10 minutes of starting use.

Good Day. A warm welcome to the HP community. 

I reviewed the case regarding issues with the touchpad. I will be delighted to assist you here.  

Superb description, brilliant troubleshooting and terrific observations made before posting. Kudos to you for that. 😉 

Check the Mouse options under control panel: 

Start → Control Panel → Mouse → Buttons tab.  

Check the box labeled "Use MS Office compatible scroll only."  

Also, check the box below labeled "Scroll in active window only." 

 
If the issue persists, attempt the below steps: 

Attempt using an alternate/external mouse.  

(If that works when the touchpad is disabled on Synaptic software, it would mean that it's a touchpad failure, 

However, if the external mouse doesn't work either, it could be a software/driver issue). 

Uninstall and reinstall the drivers for your mouse: 

Go to the Device Manager and select your mouse. Uninstall it and then restart your computer. During restart, your mouse driver will automatically be reinstalled. 

• 1.   Click on Start and type ‘Device Manager’. 

• 2.   Click Device Manager. 

• 3.   Click + sign next to Mouse. 

• 4.   Right-click on mouse entry and choose "uninstall". 

• 5.   Restart your computer.

Keep me posted. 🙂
