I have an issue with my Thinkpad Yoga (20CD).
Sometimes after I have left my Yoga unattended. I come back and find that it's on (red light on) but screen is black, but nothing happends when moving mouse or pressing keys.
I believe this is happens with regards to sleep mode.
I still have some analysis to do wether it happens when power is connected or not, external monitor is connected or not.
I have installed all the latest drivers from lenovos website.
