Thunderbolt 3 Workstation Dock (40AN) USB ports not working after updating my Thinkpad X1E1 (20MF) to latest thunderbolt firmware

2020-03-18, 17:52 PM

I just updated my Thinkpad X1E1 (20MF) to the latest thunderbolt firmware (NVM 50.00) and now I have a new problem I didn't have before:

 

When I restart the laptop, my external monitors are working OK, but all the dock USB ports are missing.

If instead I do a full shutdown and then start everything is working fine.

 

Dock firmware: v3.1.66

Thinkpad thunderbolt firmware: v50.00

Thinkpad thunderbolt drivers: v1.41.789.0

I have the same problem only with a Yoga 370. Worked perfectly until last weekend. I have updated all drivers, I even tried to reflash the BIOS several times. I have a dell that works fine when plugged in so I know it works still. It can see everything plugged in except the display ports. I also saw that two updates came in from microsoft and tried to remove the updates only to have it fail and say that "An error has occurred" and it will not uninstall.

I just setup a p73 with a thunderbolt 3 last night and it didn't work at first Display was all over and mouse erratic.   I flashed the firmware of the thunderbolt 3 and installed the software and it worked great on a pair of brand new 4k monitors for 30 minutes or so.  I powered down the laptop "which i have had for a week" and came back 30 minutes later booted up no video only amber color on dock.   I also started hearing a device detect not detect sound in windows.  Went to device manager and noticed the usb controller was going in and out along with the thunderbolt object under software components.   I thought maybe it was a driver so i removed drivers, reinstalled what was on the lenovo site.  That didn't work, so i went to a diag boot still same thing detect not detect every 5 seconds drove me nuts.   So i then restored windows to a week ago where all things worked and issue followed even to a previous state "dock not hooked up".   So at that point i knew it was not software or drivers.   Bios is up to date as all other items per patching and lenovo management app.   As a final step i went into bios and set the thunderbolt security to none.   That didn't help either, so at this point i am 99.9999% sure that the usb-c chip was faulty and fried.  Very disappointed i paid as much as i did for a P73 and it can't handle a dock for 30 minutes.   I am going to figure out how to contact support and get that process going, but a new mother board is all i can think off unless they have something special they can offer, but based off a restore to the past not working i am very confident this is not software driven.

I love posting about a serious hardware/firmware issue I'm experiencing and being completely ignored by the official Lenovo support guys.

This is how you build brand loyalty.

Hi mircolino, Did you contact Lenovo Support directly? If not that's what I suggest! This is primarily users helping users here, moderated by volunteers like me. There is increasing Lenovo presence, but they don't patrol the entire community. They do help with some of the broader issues. Hope this helps.

I don't work for Lenovo. I'm a crazy volunteer!
