#Lenovo dock firmware update tool update

The firmware update apparently works on the older laptop models meaning that lenovo didnt test the firmware update on their current models! Given that the issue has been persisting for such a long time and affecting people's work with screens blanking out and getting stuck, constantly having to unplug the dock and plug it back in, take the power out of the dock, the dock USB ports not working, then having to do restarts of the laptop, it's been a real shimozzle to say the least. Little testing has been done by Lenovo, otherwise the fault would have been detected in development. These are business laptops used by typically business users, on Lenovo's high end laptop models and high end docks (I purchased 2x $500AUD each !). Lenovo needs to work on their in-house testing before letting firmware updates go to I agree.

A $300+ dock should not be susceptible to faulty driver updates such as this. This kind of a fatal failure should be addressed right away. or someone else from Lenovo - I hope this message helps. Nevertheless, my 3 monitors are now paperweights until someone figures out a valid engineering solution (not a hack) to this issue. I don't know how the communications to this IC in the hub is done, but it seems that some update is taking down the communications method to it, hence causing the failure in the firmware upgrade tool, since the IC firmware can neither be read (reason for the DP Hub FW version 0.0.0 message), nor updated. Windows popup box came up with the same text as the in the log file - Can not find Synaptics MST DP hub IC. Tried running the vmmupdater.exe tool from cmdline (vmmupdate.exe -v) to get the current version number of the FW. Opened this file up and the following were the contents :Д®rror description: Can not find Synaptics MST DP hub IC Tool ran with similar results as the 'Check' button.no luck, still reported the infamous DP Hub FW version 0.0.0 message and failed all 3 update attempts.Run the thunderbolt 3.1.70 dock firmware upgrade, this time clicking the 'Upgrade' button.The DP hub FW version still read 0.0.0.discouraging Tool ran but took maybe 5 minutes to say it was complete.Run the thunderbolt 3.1.70 dock firmware upgrade, clicking the 'Check' button first - interestingly when trying to run the firmware upgrade from Lenovo Vantage, the check button did not appear, only the Upgrade button.strange.Download and extract the Lenovo 3.1.70 thunderbolt dock firmware upgrade - trdockfw3170.exe driver update.Download and extract the Intel Graphics n2tdr44w.exe downgrade as mentioned by Run the Intel Graphics driver downgrade package in Admin mode.And - I've tried the same steps as you did on my X1 Carbon 9th Gen - Type 20XW.
