Thunderbolt 3 Dock with T470s Bios options

2017-06-16, 6:52 AM


I just would like a description and confirmation on what the following options do under the Thunderbolt 3 dock in the Bios for this series laptop


I tested the option "No security" and this seems to bypass the authentication pop up when logged into Windows when plugging in the Thunderbolt 3 dock. So essentially it enables network ethernet connection to work straight away


Can someone tell me what the other options do?

Solved! See the solution

Hi Drekko,

Warm Greetings & welcome to Lenovo Community, happy to have you here.

As I understand that you have query regarding Wake by Thunderbolt options in BIOS Setup for ThinkPad T470s.

The following are the Security options for Thunderbolt devices as per user guide

  • No Security: Allow Thunderbolt devices to be connected automatically.
  • User Authorization: Allow Thunderbolt devices to be connected after user authorization.
  • Secure Connect: Allow Thunderbolt devices to be connected with a saved key that has been approved by the user.
  • Display Port and USB: Allow only DisplayPort-compatible devices and USB devices to be connected. Thunderbolt devices are not allowed to be connected

I hope the above information helped you.

Please feel free to post in Lenovo Community Forums if you have any further queries!
