Windows 10: Touchpad does not work, 'synaptics device not found'

My touchpad does not work at all, so I tried uninstalling the touchpad driver to reinstall it, but the reinstalling does not seem to work. The driver I tried to install gives me the notification 'Synaptics device not found' whenever I try to install it. I have a lenovo ideapad Gaming 3-15ACH6 Laptop - Type 82K2 serial number MP248R6V, and the official lenovo site does not even seem to have a driver specific to my device? When I go into device manager, it only has a mouse in the list, as if the computer believes it does not even have a touchpad. What do I do?

Hi Leagyl

Greetings! I am Vijay, an Independent Advisor.

Take actions related to touchpad driver

Synaptics touchpad - scrolling issues after Win7 to Win10 upgrade  

Well, there's more to report.... and possibly progress, although with a slight twist.

A conversation in another thread with @Try3 led me to a guide he had produced here about searching for drivers (in this case for a touchpad) using the Hardware ID.

So I found the ID for my touchpad and went looking. I couldn't find anything through a search on the Synaptics site. But the search led me to one or two download sites (filehippo was the one I went to) which apparently offered drivers for this touchpad. I downloaded v.19.2.17.59 - and installed it.

To my slight surprise, and great relief, the touchpad works with this more recent driver. The good news is - it now also scrolls properly in the Win10 Start Menu and in Settings pages, and in the MS Store - all the UWP-designed apps where scrolling didn't previously work.

The weird news is that in Device Manager the touchpad is now listed as a Dell touchpad. The driver still shows as manufactured by Synaptics. But the Synaptics tab for additional settings (with all the options listed in my earlier post #9) has gone.

I suppose if I had followed @Bastet 's advice to try the Precision touchpad driver, something similar would have happened?

Anyway - I suppose this is a step forward, in that the scrolling problem is resolved. No help from either the Samsung support or Synaptics websites, but ultimately this forum has both identified the cause of the problem (UWP apps - thanks @jbcarreon123 ) and suggested a solution (thanks @Try3 ) albeit carrying a Dell label.

 

Synaptics SMBus touchpad not in devices

Hello,

My Synaptics SMBus touchpad is not in the list of devices in the devicemanager. It has removed itself i think.

Of course the touchpad is not working.



Is there any way to add this again.
