Thunderbolt terminal of ideapad 720s-15IKB cannot read data (powers only)

2020-09-19, 10:52 AM

Thunderbolt terminal of ideapad 720s-15IKB cannot read data (powers only).

 

I have thunderbolt (usb-c) hub. The thunderbolt terminal of ideapad only gives power, but cannot read data.

The other usb-c port (not thunderbolt) can read data through the hub, so it may not the issue of my hub.

 

How can I solve it?

I reinstalled the thunderbolt driver here (https://support.lenovo.com/kr/en/downloads/DS501767 - I can't sure the page can be opened globally), but the issue is still remained.

 

Thank you for any suggestions,

Reply

+ I just re-installed Windows 10, and the issue still remains.

 

On Device Managements, Intel(R) USB 3.1 eXtensible host controller 1.10 appeared to be work, but it cannot read anything. (Data read from disk, wireless LAN conneciton, etc.) But it reads the hub name (USB 2.0 BILLBOARD).
