Help needed with Synaptic touchpad driver

[Nathan421]

Hello - My touchpad is not working on my laptop top after a Fresh Start. After searching for solutions, I have been unable to find a driver online that will work.

HP ZBook Studio 15.6 inch G8 Mobile Workstation PC (46N54AV)

Product4M1Z3UT

Windows 10 Pro

Version 21H2

I see that in most help forums, the most common advice is to go to device manager and update the driver; In device manager, the Synaptic Touchpad is not listed. I have clicked "View > Show Hidden" to no avail. I have identified the generic "HID Compliant Mouse" driver the the TouchPad is using, but updating that has no change. I have also attempted to install older drivers from the internet, but none have worked. I was able to see all of the drivers provided for my machine on HPs website, and there is a Synaptic driver for the finger print sensor, but no other Synaptic drivers or drivers for the touchpad. Can someone help me locate the driver for the toushpad on this machine?

Thanks in advance.

Hi @ub6424 -

Thank you for your response. I updated BIOS and the drivers in the sequence above. There is no change in the touchpad performance. I still do not see the Synaptics Touchpad in the Device Manager.

Any other thoughts?

[ub6424]

Send me a screenshot of windows device manager, look for unknown devices with a yellow exclamation mark.

[Nathan421]

Thank you again for looking into this matter and sorry for the delayed response. I have attached 3 images of all the items in Device Manager with the View option to include "Show hidden devices".

Hi @UB6424 -

The touchpad "works" in that I can move the mouse around , but it acts like it always has the left-button pressed. So, when moving the pointer around an empty desktop, it is drawing a box as if I was selecting a group of items. Similarly, when I mouse over a window or menu, it selects the first thing it touches. This is almost like "ClickLock" is turned on permanently (it is not).

I currently have the default drivers disabled so the Touchpad is "Off" and am using a USB mouse.

I feel like installing the Synaptics driver for HP will solve this, but it is no where to be found.

Any thoughts?

Hi @ub6424 -

I installed the drivers above. No change in the touchpad, but the fingerprint reader stopped working.

Once again, I appreciate your time and efforts.
