And it should be noted, that if the laptop is out of warranty, Lenovo will charge you for the motherboard replacement, even though the user is not at fault. Such a scam

And it should be noted that the Lenovo Vantage support tool does not update the thunderbolt controller firmware automatically which is an impossible situation for normal users to understand!

This a real discrace, thinkpad quality is completely gone.

Check the T480 and T490 thermal throttling problems too. These laptops with newest updates drop CPU clocks in a dock to 200-400MHz levels on NORMAL desktop workday usage. This has been going on with 1.5 years without a fix! And no this is not a problem of one single thinkpad but several. Disappointing totally...

It is a total shame for lenovo for leaving the customers whose had the warranty expired just a few month ago with the problem, especially as the customer has no impact at all to the failure... It is bad design problem.

Responsible companies like toyota fix their cars for free if there is a common problem found even if the car is 8 - 10 year old !

It should also be noted that the firmware update only mitigates the problem until the hardware fails for good (when warranty is exipired?)

These problems happen after a firmware update to the Thunderbolt 3 controller on the motherboard. Where I work, we have had well over 200 cases where Lenovo had to replace the motherboard. Haven't had any issues with the T470 as we use port replicators for that model. But definitely the T480s and T490s.

I am on my third carbon X1 unit for this issue and my 5th mainboard. Constant issues with HDMI and thunderbolt ports. To Lenovo's credit, the on site support has been okay, but I dread to think what my experience would have been if I had to send it away each time. I've had other issues with these laptops in the same period and would never buy Lenovo again.

all the way I thought is the adaptor until one day iI use another brand, found out the problem is Lenovo, dont know if this issue can ask lenovo to repair without a fee

As a sad X1E user my model (along with P1, both old and new gen) wasn't even listed. 6 mth into use and couldnt fast charge on Windows 10. Linux seemed fine but I main windows. Just had the motherboard replaced, same crud...I wonder they just gave up support on X1E / P1's controller firmware completely

Yea...  I haven't had this problem (yet) but from what I've read it sounds like even with the firmware fix its inevitable...  Lenovo as usual just tries to kick t he can down the road until the warranty has expired.    After the nonsense 4k screen issues with the Yoga 720 I swore off anything except thinkpad from Lenovo... now it looks like Lenovo needs to be off the list entirely.  Which is a shame as I love the track point and not a lot of choices there.

So basically they threw out their established docking system in favor of TB3... which is a great port and other venders are doing great things with it...   but they manage to muck it up in a way its not evens software but requires a MB exchange...     and Lenovo has an established pattern now (from my experience) of not fixing the product... just kicking the problem down the line til the warranty expires and expecting you to buy new.   They can get away with that for a while but their corporate customers won't.   They expect lifecycles out of their thinkpads.

So...   last updated on the 13th with a TB3 firmware update via advantage...    advantage showing now available crit, rec, opt udpates.    so ticking time bomb?     Hmm...   my TB3 dock 'died' a couple months ago...   maybe it didn't maybe the TP did.  Haven't replaced the dock yet so can't test.   

Too little, too late. My x1c 5th Gen stopped charging and I replaced the Mobo. Doubt Lenovo will refund me for the cost of replacing the motherboard.

I noticed very early that charging from one of the two ports made my X1 tablet 3rd gen soon very hot. So i always charge through the other. Maybe this issue is related. Both my c-ports work fine until now.

Something should br finally said about the trackpoint huge scandal. Most new Thinkpads suffer from problematic trackpoint drifting that makes trackpoint use impossible. It is unbelievable they dont fix it and that they dont care wasting one huge advantage over competition.

Also had issues with my x380 thunderbolt, ofc it was out of warranty. the issue was the 8 mbit flash chip where thunderbolt firmware is written, so i,ve replaced it with another flash and worked again. that flash chip is the reason they replace the mobo.

OMG! What about Legion Legion with Thunderbolt Controllers?

Very disappointing news. Already updated thunderbolt firmware to the recommended version via fwupdmgr (I'm on Linux), but it it's true about the firmware not resolving the issue permanently, I guess it's a good thing I purchased my X390 from Lenovo during a "back to school" sale period middle last year and got the 3yr on-site warranty, 3yr accidental damage protection and 3yr battery warranty included for free.

The flaky Thunderbolt port, mine stopped working less than a week after purchasing my X1 Extreme (back in January 2019) was the reason I finally dumped Windows for MacOs.  Lenovo's software for the controller combined with BIOS issues pushed me over the edge.

But the keyboard replacement programm from Apple is also limited in time, just like Lenovo's warranty, right?
Or was that a troll post, as you talk about Windows and MacOs, instead of Lenovo and Apple, as this is not an issue in the operating system?

I have a ThinkPad Carbon, 6th Gen, which is about 6 months old. UBSC problems have been severe for more than a month now. One of the USBC outlets is completely dead--the Thunderbolt 3 is the one that is dead.Just downloaded the software--both parts of it--and ran the update. The UBSC is still dead. So this does not fix the problem for me. Already have a call in to Lenovo to do a motherboard replacement. This is a very big deal for me.[

Does anyone know if this happens on Linux as well? According to Lenovo documentation this happens on Win 10 64 bit only.

year 2023 I have a ThinkPad Carbon, 9th Gen
still facing the same problem with latest BIOS and latest win10 64bit 22H2 and latest drivers from Lenovo Vantage

the USB-C is only charging at 15W
somehow power adapter fails to communicate with the laptop controller to use USB-PD mode for fast charging
