My Yoga 910 turns off the external screen - not when I do anything at all - but when sitting in front of it with external screen. When I leave the desk - then it turns itself off - or rather turns the external screen off. It is sooo weird - I do not TOUCH ANYTHING - just by myself standing up and walk away. It does not happen every time - more like in periods - some days it days - everytime I go away. Other days it just behave normally.
This happens when i use my Yoga as a desktop with external screen, external mouse and external keyboard and only using external screen.

Might help to know the make and model of the "external screen" and how it's all connected. Makes and models of adapters, etc.

There is one solution that worked for me with basically any computer: caffeine. Caffeine is a tiny program that keeps your computer from going to sleep or locking you through inactivity. Of course I recommedn you use it only if you are able to keep your computer safe, as in at home, or when you know you will not leave it unattended. That said, here is one link: http://www.zhornsoftware.co.uk/caffeine/index.html
If this does not work you can find it on the Net in many places. I also wrote a small batch file with it that allows setting of how many seconds between signals. If you need that email me.
