Re:Lenovo X1 Carbon Gen 9 Throttling Issues

2021-05-10, 2:18 AM
Well even the lg grams which have worse cooling (I guess the X1 carbon can cool about 28w CPU only, while lg Gram 2021 can cool around 23w CPU only - throttle much better and thereby have better performance overall for games, and can get close and sometimes even overtake in benchmarks. Throttling should be steady lower speed, that way you get best efficiency. At turbo speeds, intel loses around 30-40% efficiency vs medium and low speed CPU. So going up and down all the time will give you lower overall performance, besides of course for games stuttering...

Re:Lenovo X1 Carbon Gen 9 Throttling Issues

Any updates on this?  What is the likelihood that Lenovo will address this issue?  With the upcoming Memorial Day sales I'm getting close to wanting to pull the trigger on a X1 Yoga Gen 6 (which suffers from the same issue as the Carbon Gen 9), but if it's not likely this issue will be addressed I might just have to go to the competitor and get something like an HP Spectre.  As this throttling issue would be a deal breaker for some of my use cases.

It's clearly a problem that should be fixed, not only because it has serious impacts, but also because since the problem doesn't happen in battery mode, it is clearly not a design option.

Anyway, your public message here is at least way more assuring than "no problem, everything is work by design, no fix on the way", which was the official response until you posted the message here.


In fact, the previous official message wasn' even on the same page with the rest of the users. The users are talking about the abnormal behavior of the CPU and iGPU when thermal throttling, while the previous official message was saying the existence of thermal throttling is intended (of course we know that).

I've been following up the analysis and many thanks to you and others for raising up this. Now I just would like to know the answer: Is this issue also happening from previous models (ex: gen8, gen7, etc...)? If the answer is NO, I know what to do (to purchase gen9).

Dear users, 


Appreciate your quick feedback.

This issue had been raised to related team.

There will be a BIOS/ECFW fix coming soon.


Thank you.

Well what a great message, if this solves the problem, I am super hyped to order the X1 yoga gen 6! @all please report if the new bios that should be coming soon fixes the issue. I am thrilled to hear from your experience!

@otsuki what do you mean by coming soon? 


I will get my replacement today and my guess is that the throttling issue will be the same as with the one device i am getting the replacement for.

Going back to an earlier response - the problem is so bad it's not just gaming - I couldn't even record a proper instructional video via OBS Studio @ 1080p 30fps without the frame rate dropping to 5 fps every now and then.

Yeah, that's why it is complete nonsense when someone argues that "X1C9 and X1Y6 are designed enterprise business systems and not gaming systems which have very different thermal dynamics and behavior".


Well, the two laptops in their current stats are practically unusable when running more demanding "enterprise" software. The same behavior is observed even when doing a hardware scan using Lenovo Vantage. That's Lenovo's own software!!! How is that argument of "enterprise business system" even holds when it failed on its own software? Is that what your business customers deserve? A laptop that will basically crumble under 50% load?


I hope that when Lenovo says fixes are coming "soon", it literally means "soon" and not like half a year later.
