Lenovo S740 - Trackpad not working

Hi, sounds odd.

- in what way- did you get an error message?

If you boot to your BIOS does the touchpad work then?
And in Safe Mode?

I would have suggested trying Lenovo System Update but it seems yours isn't supported by that. (Works nicely for mine).

What happens if you choose to remove the HID compliant mouse completely in Device Manager and reboot?

 

Lenovo S740 - Trackpad not working

Hi I'm in urgent need of my trackpad working because tomorrow is the day of a college exam which requires me to bring my laptop without a mouse.

I've just (3 hours ago) installed a fresh copy of Windows 10 1709 .

I've since used Windows Update to update to Windows 10 1909.

I thought Windows Update would provide the trackpad drivers but it didn't.

I've tried to download and install the provided trackpad drivers off the lenovo website but it didn't work. Here's the link to the download page for the drivers laptops and netbooks :: yoga series :: yoga s740 14iil - SG. But it didn't work also.

Things I've also tried:
"Scan for hardware changes" in device manager.
"Show hidden devices" in device manager.

Here's how my device manager looks like:




Many online forum posts suggested to change a setting in my BIOS, but I couldn't find it.

Here's how my BIOS looks like:

Can someone help me out? thank you so much

By the way my full windows version is : Windows 10 1909 Build: 18363.997

 

Lenovo S740 - Trackpad not working

Hi thanks for your prompt reply!

1: I did not get any error messages, in fact it said it successfully installed the trackpad drivers. However after a reboot, the trackpad still wasn't working.

2: Safe mode, same issue. Trackpad isn't functioning.

3: I just tried it. When i remove the HID Compliant Mouse from Device manager and reboot, it will appear back inside the device manager. And still the trackpad isn't working :/.

I also can confirm this isn't an hardware issue as 3 hours ago before i installed this new windows, It was working fine on my previous OS.
