Making sense of i2c

Hi all,

I bought my daughter a Lenovo Yoga 510-14AST for Christmas. Everything
works in Linux (Fedora 25) except for the touchscreen.

Its not appearing as a USB device. At startup there is an error as it scans
the i2c bus (which seems a likely place to find the device).

Its currently running dual-boot with MSWindows. There I can see that the
synaptic.sys driver is loaded, but I don't know how to divine any further
details on how it is plumbed.
