Hello,
On my laptop (thinkpad Yoga model 20CD), when I rotate the front of the base up, the keyboard shuts itself off until I rotate it back. The issue does not occur if I rotate the back of the base (the side with the hinges) up, and does not occur in grub.
More interestingly, the problem occurs about nine out of every ten reboots, and the remaining 10% are evenly split between the keyboard not working at all or working always.
DMESG for one complete rotation (up and down):

I'm not sure where to report the bug, so I'm emailing here.
I'm running Ubuntu 16.04 on 4.4.0-109-generic.
Let me know if there's anything else I can report.
Thanks,
