T470 Thunderbolt firmware update/HDMI

2019-09-29, 4:38 AM

Today, I noticed that my USB-C docking station was no longer passing video from my T470 to my monitor. The monitor's HDMI cable is plugged into a docking station that is connected to my T470 via USB-C. It's been working fine for more than a year. All other connectivity via the docking station works (e.g., keyboard, mouse, ethernet, power). The docking station, including video, works just fine with another (non-Lenovo) PC.

 

My first thought was to check Lenovo Vantage or the support website for Thunderbolt software and/or firmware updates. The most recent software is several months old and already installed on my machine. I can see that there's a relatively recent firmware update on the website, but it's specifically for Windows 10 1809 or older. I am running 1903. When trying to install that firmware update, I receive an error message (can't find suitable bin file). Vantage does not find any updates for me to install.

 

I did see this post, which mentions HDMI output not working as a symptom (among others). However, it recommends the Thunderbolt software that has been installed for several months as well as the firmware that I cannot install.

 

I have two questions:

  • Is anyone else having problems with HDMI output via their T470 USB-C/Thunderbolt port?
  • Is there any news on when there will be a new T470 Thunderbolt firmware update for Windows 10 versions newer than 1809?

Hi SoCalJB! Welcome to our forums community. Was there any updates installed or any changes made before the issue arise? Try updating the firmware and driver of the docking station here: https://support.lenovo.com/us/en/downloads/DS501903 then check if the issue is the same. The Lenovo Vantage app is intended for Ideapad line while the Think Vantage app is intended for Think lines like your laptop. We suggest you to install Think Vantage instead then run the update, install all available updates. Update us how it goes.

Hi @Jwes_Lenovo. I should have been clearer that the docking station is not a Lenovo docking station, and there are no firmware updates for it. However, my T470 is still under warranty, so the mainboard was replaced and that resolved the problem.

 

Can you point me to a link to the Think Vantage app you mention? My two Thinkpads both came with Lenovo Vantage preinstalled on them. If they should have come with the Think Vantage app, I'll take a look at that.

Sorry for the confusion, the Think Vantage app was migrated to Lenovo Vantage app for Windows 10 devices. You can get the
Lenovo System Update for Windows 10 from this link: https://support.lenovo.com/us/en/downloads/ds012808. Let us know if you have other questions.
