If you have a Lenovo Yoga 3 Pro and suddenly the touch pad stops responding even though the drivers are there, do check the following:
- Open Device Manager
- Expand Human Interface Devices
- You should see a warning next to one of the I2C HID Device
- Try to disable the drive (right click over it)
- Then Enable it again
- The touchpad should come to life again 🙂
- If not, try to reboot and it should work
This has caused me a lot of frustration in the past. The driver continues to fail occasionally (not sure why) but the above fixes it.
This Yoga 3 Pro was originally running on Windows 8 and upgraded to Windows 10 so am not sure if this is one issue related to the upgrade
