Lenovo Legion 7i USB-C/Thunderbolt 3 Docking Options

2021-04-08, 7:24 AM

I'm confused when it comes to how to use the ThunderBolt 3 port on my Lenovo Legion 7i. I want to be able to use it to connect to a USB-C/Thunderbolt 3 dock (confused about the difference), but most of the docks I am looking at say they allow 85-100W of charging through the tb3 port. I know the Legion 7i does not support charging via USB-C, but if I connect it to the TB3 port, will I be accidentally damaging my motherboard or my laptop in general?

 

Or does anyone know of any docks that'll support a dual 4K@60hz display setup? I have everything connected to my laptop atm, but I want to be able to just use the dock instead to minimize wires connecting to the laptop as much as possible, so I can just close the screen and vertically mount it.

Hi DuxInfernum,

 

Welcome to the Community Forums.

 

When connecting a dock to the UBS-C / TB3 port, you'll benefit from the bandwidth from the port if the device does not support being charged through it, as there is no handshake between the dock and the computer to allow it, and there will be no harm done to the computer.

 

However, the Legion 7 (Machine Type:  82N6, 81YU, 81YT) does not show any compatible docking stations on SmartFind. So I can not guarantee that any will work or be fully compatible with the device.

 

Regards

 

Voithos

Hi Voithos,

 

Do you know how I can physically check compatibility with the device? Will I have to just buy a dock and test it out?

 

Thanks for the quick reply,

Dux
