Yoga 720 USB C port HDMI and USB port not working together

Hello, I am having a hard time to make drive hub HDMI and USB ports work well with neither of USB C ports with this Yoga 720-13IKB

 

If i plug my drive hub with USB C power port (the one far away from the back, but close to audio plug), HDMI ports for monitor through the drive hub can work, but not USB ports for mouse.   

 

If i plug my drive hub with USB C regular port (the one close to the back), HDMI through the drive hub cannot work, but USB ports.

 

The drive hub i am using is HD30F Power 9 in 1 gray. The laptop is also updated with latest drive. 

 

Kind of frustrated with this laptop. 

 

Can some one help me out?

 

Thank you

Re: Yoga 720 USB C port HDMI and USB port not working together

Hi @Houstonrender,

 

Welcome to the Community Forums.

 

Based on the diagram below for Yoga 720-13IKB, the USB Type C port on the left side is connected to the graphics card going to the processor and the function is for display only. The USB port on the right side is for USB connection or data transfer. You may also learn more about the system information on our product reference

The USB C hub is detected as the adapter and it doesn't have his own power source. The USB-C is an evolving standard and compatibility seems to vary widely across devices. One reasonably sure way to guarantee compatibility is to get Lenovo-branded stuff from Lenovo, where you can check the compatibility list from our Lenovo Smart Find link: https://accessorysmartfind.lenovo.com/#/

 

Hope this helps.

Auxen

Auxen,

 

Thank you for the note.

 

Are there anyway I can use only one adapter or hub to hook up with regular USB C port on the left handside, so that i can use both USB and  HDMI simultaneous through the adapter or hub?

 

Please see my markup in image below; probably my picture can give you a better idea.

You can use a docking station to use HDMI and USB at the same time. You might want to look over this thread and this thread for some answers.
