ThinkPad Yoga X1 gen 6 overheats after two weeks of use with Ubuntu 20.04

2021-06-16, 17:35 PM

Hi all,

 

I have the new ThinkPad Yoga X1 Gen 6 for two weeks only and I am using it with Ubuntu 20.04. I mainly use the laptop for scientific simulations and with this new model there is something wrong that makes it impossible. If I open Matlab2021a, for example, and run any small piece of code, then after a few second the temperature from all the cores reaches 95 degrees (according to Psensor) and it shuts down. It happened with Zoom a few times as well. What should I do? Is it some hardware problem or is there some thing I can do in the Linux environment in order to adjust the fan and temperature control?

 

Thanks a lot for the help.

Hi,

 

Can you let me know which BIOS and EC versions you have on there please? Are the fans kicking in? Can you share some screen shots of psensor maybe?

 

If it's possible to share exactly some repro steps that will be good. You obviously shouldn't be seeing that behaviour and we've completed cert on that platform without this kind of issue being reported.

 

Thanks

Mark

Hi Mark,

 

thanks a lot for your answer. When I use dmidecode, it gives me

 

BIOS Revision: 1.15
Firmware Revision: 1.11

 

ThinkPad Embedded Controller Program
    Version ID: N32HT33W
    Release Date: 02/09/2021

 

Do you need anything else?

 

Regarding the fans, they work normally but the moment I open Matlab and start to use it, they get completely crazy and start to work at full power. And then the computer starts to overheat until it shuts down. The whole process is very quick.

 

The Psensor screenshot is attached. The first jump occurred when I started Matlab and the second one started when I start the simulation. Then, I cancelled the simulation and it drops back to the previous temperature after a few seconds (also the fan calms down).

 

Thanks for the help!

Claudio

Your BIOS and EC are very old, please update to a more current version the latest EC is 1.26 and the latest BIOS is 1.42

Hi DaveOber,

 

thanks a lot for the information. I am layman in this topic but, to be honest,  I find that this model was just released very contradictory with the fact the the BIOS is very old. Also, now the laptop started to overheat also when I use any software with video like Zoom, Jitsi or Skype. If I turn the video off, the temperature decreases, but the the video on, it shuts down after a few minutes (not so fast like with matlab), which is very annoying.

 

I am also very confused regarding this BIOS update. I did "fwupdmgr update" on the terminal and now, if I type " dmidecode", it shows me

 

BIOS Revision: 1.39 (N32ET63W)
Firmware Revision: 1.25

 

ThinkPad Embedded Controller Program
    Version ID: N32HT45W
    Release Date: 05/12/2021

 

However, when I enter the BIOS, it shows me

 

BIOS N32ET39W (1.15)

EC Version N32HT33W (1.11)

 

Also, I saw that the standard update is done via Windows, which I dont have. Is there anything I can do or should I return the laptop? Thanks again

Hi DaveOber,

 

After trying it again apparently now the update worked out. When I type fwupdmgr get-history, I can see that

 

 X1 Yoga 6th Embedded Controller Update:
        New version:       0.1.25

 

 X1 Yoga 6th System Firmware
│       License:           Proprietary
│       Size:              18.3 MB
│       Vendor:            Lenovo Ltd.
│       Description:       System Firmware Version 1.39

 

But I was not able to find version 1.42, or 1.26 for the EC, as you described.

 

By searching a bit, this is what I was able to find

 

https://github.com/bes-dev/thinkpad_x1_carbon_6th_linux

 

Any thoughts on that?

 

Thank you!

One thing that I realized is that even though the ubuntu starts well (and I have the latest version of linux kernel, 5.12.12-051212-generic), before starting I get the message

 

[    0.214025] x86/cpu: VMX (outside TXT) disabled by BIOS

[    0.653921] pci 000:00:07.0: DPC: RP PIO log size 0 is invalid

[    0.654906] pci 000:00:07.2: DPC: RP PIO log size 0 is invalid

[    0.803702] ACPI FPDT: [Firmware Bug]: Invalid record 4113 found

 

but I still have the overheating problem.

If you monitor the cpu heat level how long does it stay above 90C.  when I test on mine with the latest BIOS and EC, not general available yet as still in testing phase, it goes to about 96C for less than a minute then drop the frequency down to 2.4GHZ and the Temp then drops to in the upper 60sC to low 70sC range.  There is a power tables fix in the next EC 1.26 soon to be released as it need 1.41 BIOS to go with it.  The latest released is 1.40 and 1.25 for BIOS and EC

Also I do see the two DPC output lines on my kernel 5.8.0-43-generic but not the other two line

Hi, 

Did you find any solution?

I'm experiencing the exact same problem with X1 gen9 on Ubuntu 20.4 which I bought a week ago. This happens every single time after less than 5 mins into compiling a simple code with multiple cores. Updating bios didn't help either. The log before shut down: 

Thermal_zone0: acpitz: critical temperature reached, shutting down.
