Updated the BIOS, no change, kernel log reports the same error.

That was an endeavour! I should have done it before installing Ubuntu. The
machine has only 32GB of eMMC storage so dual booting is out, I only has 16GB
USB sticks which Windows 8.1 would crash on boot, so I was left re-flashing
back to Windows then back to Ubuntu.
Let me know if you have any other suggestions.

Title:
Error initialising accelerometer DUAL250E
Status in linux package in Ubuntu:
Confirmed
Bug description:
I'm fairly certain that the DUAL250E is the accelerometer on the
Lenovo Yoga 300-11/BY.
I suspect there are two, one in the lid and one in the base, and they
are needed to trigger auto rotate and disable the keyboard and
touchpad in tablet mode. Without them these functions may be
impossible.
Note that some people reported the lid giving off key codes for
similar Lenovo tablets but that does not appear to be the case with
this one running my current software. Not sure if this is relevant to
the bug but I didn't want to dismiss the idea out of hand.
The expected functionality would of course be to perform auto-rotate
and disable the keyboard/touchpad, but at this stage I'd settle for
the accelerometer being usable as I understand this is not yet
unplemented.
I trust ubuntu-bug attached the appropriate information, but here is
the kern.log output just in case...
