Windows 10: Problem with Synaptics Touchpad on MSI PS42 8RB Notebook

Hi,I have the MSI PS42 8RB Notebook and I've been having problems with my touchpad on Windows 11 after installing new drivers using the Driver Booster program.Right now, I can only alternate between one of these two situations:1. The official MSI drivers for the Synaptics touchpad are installed they appear under Device Manager > Mice and Keyboard > Synaptics SMBus TouchPad, but also under Device Manager > Human Interface Devices > Synaptics HID-Compliant Touch pad Device, both are version 19.5.10.132. In this case, the touchpad is unable to move the cursor or to scroll, but click

Synaptics touchpad sleep problem.

Tbh I don't see Synaptics in the list.

I've tried another clean install but I am worried about this as I cannot tell whether it has installed correctly or not:




If not then I'll recover from my image.

I've heard there's a problem with touchpads not working after startup but not after sleep with 2004.

 

Synaptics TouchPad Driver Problem!

This problem sounds very similar to mine. Hoping for a solution.

I posted as a reply to <link>
"Synaptics SMBus TouchPad Drivers for Windows 10 build 1803 - HP Support Community - 6869807" but that post is over a year old so wish to bring this new symptom to the attention of HP.



After installation of Microsoft update [June 26, 2019 — KB4509478 (OS Build 17134.860)] the Synaptics touchpad ceased to function.



I tried various steps to get it back, without success. Need a solution from HP.



Here is what I've tried:

1. removal of Synaptics Touchpad device using Microsoft Windows 10 Control Panel > Device Manager

2. removal of Synaptics Touchpad driver taskbar widget from Microsoft Windows 10 Control Panel > Programs and Features

3. restart

4. download sp92533.exe (from HP FTP site) v 19.5.10.75 and install

5. restart

6. perform detect new hardware in Microsoft Windows 10 Control Panel > Device Manager

7. set View Hidden Devices in Microsoft Windows 10 Control Panel > Device Manager

Nothing seems to work. I suspect that HP needs to develop a new revision of the driver compliant with KB4509478 and/or Microsoft must repair the update to be compatible with Syntapics Touchpad.

Please help. HP Notebook computer is now becoming difficult to use without Touchpad.
