Battery life on Lenoxo X1 Carbon Gen 11

punkpen · November 23, 2023, 7:53pm

I got a new laptop, a Lenovo X1 Carbon Gen 11 but battery life is miserable.

Hibernations works with a swapfile, I’ve added

boot.kernelParams = ["resume_offset=____"];
boot.resumeDevice = "/dev/disk/by-uuid/_____";

but memory suspend is not. only s2idle is announced, and I cannot find any other setting in BIOS (updated to last version)

~ cat /sys/power/mem_sleep
[s2idle]

TLP is enabled

services.tlp.enable = true;

I’ve installed s0ix-selftest-tool and this is the result:

s0ix-selftest-tool -s

What other things should I try? If i close the lid the battery drains in 7~8 hours.

APCodes · November 23, 2023, 10:29pm

Hey welcome to NixOS!

What is the exact nature of your problem? Battery life when running or battery life on stand by / suspend?

We very recently had a battery life issue with another X1 Carbon user here: NixOS Drains my Laptop Battery in 10 min

Would be interesting to see if there is a commonality.

punkpen · November 25, 2023, 9:16am

Hi! Sorry if my question was unclear/uncomplete.

Battery life during normal usage is acceptable, mainly similar to a previous old Thinkpad X1 where I was running Debian.

My problem is with sleep (suspend to ram): the battery drains. I read several people suggesting to look in the laptop BIOS to change the suspend configuration, but my BIOS (updated to last version) has nothing to change it. Then I read about s0ix and the output was attached above
Wondering if someone else has the same laptop and what kernel tweaking is adopting. Thanks

APCodes · November 25, 2023, 10:46am

Yeah I understand now that it is a different problem.

I also have an Intel based laptop, albeit a little older (8th gen Core i7 by Xiaomi). And I noticed a difference that might actually make a difference.

When doing a cat /sys/power/mem_sleep I get s2idle [deep]. According to kernel documentation here System Sleep States — The Linux Kernel documentation, s2idle has two modes. So it indeed might be the case, as you suggested, that your laptop doesn’t go into suspend-to-ram mode but stays on standby.

I added this piece of systemd related config for my system. I mainly did this because I had problems with hibernation I believe. But maybe it helps for getting your laptop to suspend?

  systemd.sleep.extraConfig = ''
    AllowSuspend=yes
    AllowHibernation=no
  '';

As far as I can tell this just adds the two line string to /etc/systemd/sleep.conf

APCodes · November 25, 2023, 10:57am

you might also try sudo journalctl | grep "PM: suspend" | tail -2 to see what actually happend when your laptop went into suspend the last time. For my machine I get this (it slept during the night):

Nov 24 22:47:34 minotebook kernel: PM: suspend entry (deep)
Nov 25 11:13:20 minotebook kernel: PM: suspend exit

Another suggestion might be to add the mem_sleep_default=deep to your list of kernel parameters. This should go into the boot.kernelParams list on NixOS. Notice this is a list of strings, separated with spaces and inside double quotes. So it should be

boot.kernelParams = [ "mem_sleep_default=deep" ];

punkpen · November 25, 2023, 1:27pm

I’ve tried both kernelParams and systemd.sleep.extraConfig

But still suspend never goes into deep

nov 25 14:21:24 alamut kernel: PM: suspend entry (s2idle)
nov 25 14:21:29 alamut kernel: PM: suspend exit

so basically my problem is here:

~ cat /sys/power/mem_sleep
[s2idle]

APCodes · November 25, 2023, 3:00pm

Yes, your issue appears to be that the laptop doesn’t really get to suspend-to-ram. The big question is just why.

Here it would be helpful if we had someone else with a Lenovo X1 Carbon 11th Gen.

tolgaerok · November 25, 2023, 3:28pm

Try

udev.extraRules = lib.mkMerge [     
      ''ACTION=="add", SUBSYSTEM=="usb", TEST=="power/control", ATTR{power/control}="auto"''                  # autosuspend USB devices      
      ''ACTION=="add", SUBSYSTEM=="pci", TEST=="power/control", ATTR{power/control}="auto"''                  # autosuspend PCI devices      
      ''ACTION=="add", SUBSYSTEM=="net", NAME=="enp*", RUN+="${pkgs.ethtool}/sbin/ethtool -s $name wol d"''   # disable Ethernet Wake-on-LAN
    ];

Or help your self to my guthub

I’ve read many complaining in the Lenovo forum, pointing to solution like this:

I’m a bit disappointed, but not NixOS fault.
Next time I’m gonna choose carefully before buy, I trusted the X1.

APCodes · November 25, 2023, 6:09pm

I would trust Lenovo too, usually. But researching this problem in advance is hard, you need to look for it specifically. But looking at this, you might still be able to work around it.

What does sudo dmesg | grep 'ACPI.*supports S' give you?

I get this: [ 0.303949] ACPI: PM: (supports S0 S3 S4 S5)

Edit: What is strange is that supposedly Lenovo has fixed this issue in the past already. Look at this blog post speaking of a specific BIOS setting that was added for an older generation of X1 Carbon:

punkpen · November 30, 2023, 2:22pm

I’ve tried several settings with no luck. I’ve also read on the Lenovo support forum that s0ix is the only sleep supported,

And in the end I see there is a Kernel ticket still opened
https://bugzilla.kernel.org/show_bug.cgi?id=215832

APCodes · November 30, 2023, 2:31pm

Yes, but S0ix appears to have several states. Your laptop doesn’t get deep enough. That’s why I wanted to get dmesg output.

Looking at it quickly, kernel ticket appears to indicate two potential causes: wifi module or nvme drive. You could test both of those.

punkpen · November 30, 2023, 3:17pm

here the dmesg: debian Pastezone

APCodes · December 2, 2023, 6:10pm

okay I must have missed the response. Sorry, but the output is gone already. You can just paste it here in discourse. But the important line was which S-states are supported.

punkpen · December 3, 2023, 10:29am

(sorry for the external paste)

here the output:

dmesg | grep 'ACPI.*supports S'
[    0.369003] ACPI: PM: (supports S0 S4 S5)

Yesterday I upgraded to NixOS 23.11, things are slighy better, probably new kernel.
(unrelated: this the first NixOS “dist-upgrade” for me, works like a charm compared to other distro, full love)

APCodes · December 3, 2023, 10:34am

Yes, so as we can see, it doesn’t “support” S3. Which it should. And which it does on my Intel laptop. And which is probably the main issue for your energy problem.

(Yes, that is why I started and kept using NixOS at the beginning. It is a better third option to the dichotomy of rolling-release Arch vs. Debian-style dist-upgrade.)

tolgaerok · December 3, 2023, 4:20pm

Oh dear, although good to hear that it went all good for you, just to let you know, ive been upgrading my fedora kde from 37 - 39 without a glitch - including the nvidia + wayland upgrades.

All distro’s have there strengths, nixos is a brilliant sandbox distro where as fedora workstation is a brilliant desktop and daily platform / distro …

APCodes · December 3, 2023, 8:29pm

I’ve been daily driving NixOS for a while now. While Fedora is always my preferred Sandbox distro

But Fedora is indeed a really good distro. If it wasn’t for NixOS I would surely look at it as a potential daily driver for me.
