Brand New Lenovo Yoga C740 14 IML - Touchpad not working in Windows 10

2020-01-31, 2:34 AM

Brand new Yoga C740 here. After first Windows 10 boot and setup, touchpad is not recognized, nor disabled or hidden on device manager.

I tried a hard reset refreshing windows 10 and again touchpad not even recognized.

 

I know touchpad works because in Bios, cursor is moved and buttons works, so doesn't seem to be a faulty hardware.

 

I was checking the drivers section for the laptop but there is no driver for touchpad there. So what's brand is the touchpad of the Yoga C740? Any alternative driver i can use for it on Windows 10?

 

Thanks in advance

Solved! See the solution

So the touchpad driver is shown to be unrecognized (with a yellow exclamation mark icon) in the device manager right?

Try to uninstall that driver and restart your device. Windows should fall back to the generic driver. Then you can find a suitable driver afterwards.

 

Prepare a USB mouse for that, in case things go wrong.

Hello, thanks for your answer.
No, as i mention is not even in the device manager, and there is no device with exclamation mark.
I tried several times the "search hardware changes" option and nothing appear. That's why i would like to try installing some driver to see if it's recognized. I don't understand how is not detected by Win 10 but works in bios.

Talking with a few Lenovo support guys and they were not able to fix it.

 

But i got it working after updating Intel Serial-IO driver (i really not sure if it has something to do with the touchpad), and uninstalling the keyoard driver that was detected by windows 10 from device manager. Once i restart everything was working ok.

You updated Intel Serial-IO driver found in the device manager? Under what category. I'm having the same problem with the same laptop model.
