Re: Yoga 730 15 dock compatibility

>>> My point is it appears the 730 does not have the "DC -in function", which leads me to believe it's data only

 

This is not correct. The product description clearly states that loading via usb is possible.

 

With revolutionary connection technology Thunderbolt™ 3 via USB-C, 
the Yoga 730 offers a fast and versatile connection to high-resolution displays*,
powerful data devices and more - and can be recharged quickly at the same time.

I understand the product desciption may be incorrect or misleading. Look at the datasheet for both Yoga 920 and 720 under "ports". The TB3 discription is different.

USB 3.1 Type-C Gen 1 (with the functions of Thunderbolt 3),
audio combo jack, AC power adapter jack

 

The naming of "AC power adapter jack" is specific Lenovo an tells you can charge over USB.

Also the Thunderbolt 3 specification tells it is possible to load over usb-c

 

Thunderbolt 3 has limited power delivery capabilities on copper cables and no power delivery capability on optical cables. 
Using USB-C on copper cables, it can incorporate USB Power Delivery,
allowing the ports to source or sink up to 100 watts of power.

https://en.wikipedia.org/wiki/Thunderbolt_(interface)#Thunderbolt_3

I think here is no misunderstanding. It is clear that here the charging over USB-C is advertised and described

But not clearly is the detailed technology of the USB-C Port

 

?? - USB Power Delivery Specification Revision 2.0, Version 1.0 ??

?? - USB Power Delivery Specification Revision 2.0, Version 1.2 ??

?? - USB Power Delivery Specification Revision 3.0 ??

no...ac power jack is simply another port on the list....the specs are not telling you that the thunderbolt port is an ac power adapter and a audio combo jack...

it is listing the ports on the system.

You are confused
