Touchpad acting extremely erratically

HP Recommended
Pavilion 16t-a000
Microsoft Windows 10 (64-bit)

I have been having a problem with my laptop since I got it.


While my touchpad works fine 80-90% of the time, there are times where it will behave rather weirdly. Sometimes it would not register my finger at all. Other times it would act too sensitive, moving the cursor way too erratically, making it jump across the screen. These moments are short and eventually resolve themselves, but they keep coming back.


I can say that these episodes seem to occur usually when I plug in a different input device, such as a mouse or a drawing tablet. However, they also frequently occur by themselves.


I have been made aware of a "Synaptics Touchpad Driver" from previous searches, but when I checked Device Manager it appears that my laptop does not possess this driver and, to my knowledge, it never had in the first place.


Is anyone able to provide some insight/advice? Thanks.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

  1. To open HP Support Assistant, double-click the HP Support Assistant icon
  2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
  3. Click Check for updates and messages to scan for new updates.
  4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
  5. Click the update name for a description, version number, and file size.
  6. Select the box next to any updates you want to install, and then click Download and install.

Hope this helps! Keep me posted for further assistance.
