Don't know if there may be a problem with the lid sensor then
Don't know if [https://www.ebay.com/itm/5C50H15168-Lenovo-Sensor-Board-C-/133421634682|this - example only] is it or not.
Found this by looking at the [https://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/yoga-series/yoga-3-1170/80j8/parts/display/compatible|parts list] (click on ''Select Commodity > cards misc internal (4)'' to find the part number for Sensor Board C Yoga 3-1170 CARDS MISC INTERNAL ''5C50H15168.''
The [https://download.lenovo.com/consumer/mobiles_pub/lenovo_yoga_3_1170_hmm.pdf|hardware maintenance manual] shows that it is near the camera board and is located in the top of the lid. (see p.54)
Try covering it up somehow (or does it need a magnet??) and check if you don’t have to close the lid to keep the laptop on.
Or perhaps the EDP cable may be damaged where it passes through the hinge to get from the motherboard to the lid, as the webcam and sensor wires would be in this cable, I think.

When using the external display this means that the laptop display is off is that correct?

I may be totally off the track with this off course, but it seems that something with the lid is conflicting with maintaining the laptop on as per normal.
Hi @yusuf10
Not a problem with your English, it's fine ;-)
