Hi, I'm using my Yoga 900 on the desktop for longer periods of time. When it awakes from sleep it does not always "remember" that it was last displaying on the external monitor. Sometimes I have no picture at all, sometimes I have the picture on the internal monitor. When I switch to external only with F10, it won't do that, so the external monitor (HP 24es) won't wake up. Up to now my only solution is to plug out and back in the Type C adapter (Apple 3x multi adapter). That's definitely not what I want to do several times a day. Thanks for any hint...!

Thanks for using the Lenovo forums.
Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.
(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal
Also try to download the Video and Chipset drivers for the unit from the support page.
Hope this helps, let us know how you get on.

I too have had this problem for over a year. This model is a lemon :-( Worked with tech support, but they could not get it fixed. I sugest you return it and get a different computer model because it's a bad design. Else never let it go to sleep and just let the displays turn off. 4K displays are a bad idea because they don't play well with other regularextended displays.
