Re: [X1C6/T480s] low cTDP and trip temperature in Linux

I mean, I am hoping we all get it real soon. They don't seem to care who has waited longest as the first bug fixes came for the brand new models like the X1C7. I thought they might be working backwards.

Anyways, the X1C6 has been waiting longer than a year too. The X1C6 and the T480s were both released in 2018 so I don't get what your point is. They are really in the same boat for waiting time.

Hi Mark,

Any update on the X1E (and others)?

I will be stopping by from time to time asking this very same question. I beg for apology in advance - don't mind me for doing it, but I don't want this to be getting lost or forgotten. Thank you.

Still working on it - sorry it's taking so long and no need to apologise for checking in :) 

There is work happening in the background and as soon as I'm allowed to release the details I will.

Mark

Personally I think it would be good if people stop asking repeatedly for updates on this thread. Mark has already stated multiple times that as soon as he has any updates to share, he will, so there's no reason to keep asking for updates.

 

If people just sit tight and refrain from posting, those of us who subscribe to the thread waiting for updates from Mark don't have to get our hopes up every time there is movement on the thread.

 

And look, now I've contributed to the noise :p

@Mark: thank you.

@estan:

Fair point. It's not my intention to produce noise either. Though I think it's more important to let Lenovo know that there's (still) a strong demand for those fixes. 

I may have sold my laptop in between because of the issues and lost interest (actually quite on the contrary - I have moved out of Windows entirely to Manjaro Linux). By checking-in every now and then (sure not every other day) but in a reasonable frequency I (and others) may signal their interest.

True that a board like this is not the best tool for such repeated signals precisely because of the noise, but as long as there's nothing better, I ought to use it.

Having said this, I am out for at least 2 weeks if not more.

Don't kill the messenger..
 
I agree with @notabenem on this one..
 
These are almost two year old, fully paid, not exactly cheap, with questional fw updates plagued (lost tb controllers, non-delivered "critical" fw upgrades for wear out issues, month-long s3/s0ix sleep state issues, tdp issues), linux certified, machines, which simply do not work as advertised. The issue(s) is/are well known in the community for quite a while (see first post date) and Lenovo had plenty of time for responsible resolution of these issues.
 
I fully understand that none of the employees are obliged to anything, as are forum user entitled to _nothing_. But please, do not critizise people whom are asking, even apologizing already, for something that should have been a implicitness in the first place. The issue here is surely not almost 200 people responding to a thread, but moreover the solely existence/neccessity of this very thread instead, i believe.
 
Nonetheless, i am a customer who fulfilled his part (paid in full for my machine), switched from the apple ecosystem after +10 years, and laid his trust in the hands of the many promises lenovo had made and, so far, and i can only speak for myself, without wanting to critize anyone personally, i am not particulary impressed.
 
I dont want to sound pessimistically, but i have become sceptical at best and do not understand where some people get their optimism from.
 
What makes you so sure about this, e.g. for how long, in your opinion, should people still "sit tight" or which comment makes you think that lenovo will indeed fix these issues at all and what gives it it's weight? I am not saying they won't, but then again, what makes you this optimistic, considering the past?
 
In this regard, seeing is believing.. personally, that is all there is to it.
 
FWIW, received to fw updates for the x1c6 today, one for the ec, one bios/uefi update, none of which helped resolve the tdp issues, quite indeed, as i'am actually now inclined to say. Still waiting for _anything_ regarding the "wear out" issue of the tb controller (actually it appears to have bricked some peoples machines/controllers already [1]) and fixed/patched the nvme wear out issue for some models manually.

Re: [X1C6/T480s] low cTDP and trip temperature in Linux

Dear all

 

Today fwupdmgr offered the following (though I had to issue 'fwupdmgr refresh' before 'fwupdmgr get-updates').

 

│ └─ThinkPad X1 Carbon 6th System Update:
│       New version:       0.1.43
│       Remote ID:         lvfs

│       License:           Proprietary
│       Size:              9.5 MB
│       Vendor:            Lenovo Ltd.
│       Flags:             is-upgrade
│       Description:       Lenovo ThinkPad X1 Carbon 6th System Firmware Version 1.43
│       
│       The computer will be restarted automatically after updating BIOS completely. Do NOT turn off your computer or remove the AC adaptor while update is in progress.
│       
│       This stable release fixes the following issues:
│       
│        • Update includes a security fix.
│       
│       For more details, check National Vulnerability Database
│       
│       Some new functionality has also been added:
│       
│        • Updated the CPU microcode.
│        • Support for non-Absolute Persistence Module version of UEFI BIOS.
│       
│       Security issues fixed:
│       
│        • CVE-2019-0151
│        • CVE-2019-0152
│        • CVE-2019-0123
│        • CVE-2019-0124
│        • CVE-2019-0117
│        • CVE-2019-0184

Is the microcode update mentioned here the throttling fix? More information would have been good. (Nor does the relevant ReadMe file - namely, https://download.lenovo.com/pccbbs/mobiles/n23ul19w.txt - seem to offer any more of an account.)

@jnWibble: CPU microcode updates mitigate CPU hardware bugs, see https://en.wikipedia.org/wiki/Intel_Microcode . Those updates come from CPU manufacturers (like Intel / AMD) and are only rolled out by Lenovo via firmware updates.

Just for anyone who is waiting for this fix for their model, why not use throttled? 

 

https://github.com/erpalma/throttled

 

It seems to give all the benefits of the firmware fix (throttling at 95 degrees and cTDP control) with support for AC and battery modes, and additionally provides undervolting as well. I'm still using it for undervolting even though my X1Y4 has the firmware fix applied.
