Weird sleep issue: laptop powers off if lid is close when sleeping

Support
1

I recently got a Lenovo slim 7 gen 8 and installed manjaro i3 on it.

I am having a weird issue. The computer goes to sleep properly either when I execute systemctl suspend or when I close the lid. However, if I suspend and then close the lid it immediately powers off. It also powers off if I plug or unplug the charger while sleeping.
In both cases, immediately before it powers off, I think it momentarily tries to power on (at least the lights in the back turn on for a second or two as if the computer was on; they are off when the computer is suspended).

Besides this, I have had no issues. Everything else seems to be working fine.

This is the journalctl for one of these events. The computer seems to properly go to sleep and then I just have the next boot after shutting down.

I couldn’t find anything relevant with dmesg --level=emerg,alert,crit,err :

I have some experience with Linux but I don’t even know how to start debugging this. At this stage I would be happy if you could help me pinpoint at which level the issue is (BIOS, firmware, kernel, …). My main question is if this is a hardware issue and if I should return the laptop.

Besides the basic manjaro i3 install I used envycontrol to turn off the discrete GPU and I am using tlp to impose battery care limits and manage power modes. This is the tlp status:

This might not depend on Linux but on your computer firmware.

Do you have the same issue with Windows?

It is useful to have bi-boot to sort things.

My computer (a Mac) has a special command to restore energy settings (“restore the SMC”) by pressing some keys during startup. Yours may have similar.

Take a look here: [PATCH 1/2] ALSA: hda: cs35l41: Add fixups for machines without a valid ACPI _DSD
Seems firmware related.

Only s2idle possible. Not a good situation, since this is purely software suspend in S0 (so called Modern Suspend), not S3 (deep suspend) what is mostly preferred. Similar to smartphone suspend. So actually, it should work, but s2idle is still not very stable on every system in my experience.

Sounds to me like LID switch, which doesn’t report “lid close” and “lid open” explicitly. Without that it doesn’t work properly on Linux:

So you suspend and then close the lid, it thinks you opened it, because was suspended. Just a thought.

sudo libinput list-devices

Example (choose another device if needed):

sudo libinput debug-events /dev/input/event0

The close the lid and open it.

It could also be, that suspend-then-hibernate is enabled by default here. It tries to hibernate, but actually no valid swap device was found, therefore it shutdowns.

However that are all assumptions.

Currently, I don’t. I was not thinking about dual-booting on this machine, but I may eventually do it if there is a change it might fix this issue.

5

Thanks for the hints. I haven’t been able to solve it yet, but at least now I have some ideas.

Indeed, that is related with the firmware for the amplifiers. Is your point that this may be preventing the laptop from properly going to sleep?

I updated the kernel to the experimental version 6.7.0 and this amplifier issue still exists. It was not clear for me, from the link you sent, if this fix will eventually make it into the kernel or if I will have to patch it on my own.

I searched a bit and this is a hardware/firmware constrain, right? Can I try to force it to go to deep sleep, even if it doesn’t seem to be available?

I also searched the bios for any option related with sleep, without success. However, I found some options about being able to charge through USB while the device is powered off, and about power on when the lid is open (from a fully powered off state), which is described as similar to pressing the power button. Both of them were disabled. It made me wonder if there might be some bug in the bios in which the last config is not being properly applied.

The output of sudo libinput debug-events /dev/input/event0 is

-event1 DEVICE_ADDED Lid Switch seat0 default group1 cap:S
event1 SWITCH_TOGGLE +0.000s switch lid state 1
event1 SWITCH_TOGGLE +1.653s switch lid state 0
event1 SWITCH_TOGGLE +253.380s switch lid state 1
event1 SWITCH_TOGGLE +255.014s switch lid state 0

Hibernating seems to work, but since my typical ram usage is 10+GB, it is a bit cumbersome. I have a 34GB swap partition and 32GB of RAM.

Any thoughts?

Hello guys I know this is old thread but I have a Legion Slim 5 16APH8 with the same issue. You’ve discussed that only s2idle ( Modern Standby ) is available but I’ve found a way to switch that in the bios. While diggin’ in some Lenovo support threads I found a way to boot InSydeH20 bios in extended configuration. There I found an option to switch between different Modern Standby options as long with the good old S3.

So without further ado to boot to the advanced bios…

  1. restart and enter bios with F2

  2. Pres Ctrl+Alt+Del

  3. (You need two hands for this one ) Immediately after start pressing Fn+R+N in equal intervals not very fast and with the other hand press F2 between that intervals. This will boot to BIOS but when you click on the More (Advanced options) button in the lower right corner there will be a lot more options for settings.

  4. You need to navigate then to the first of three options with 3 letters PBS or something like that. Under that there is an option for Power Saving and there is the Modern StandBy setting.

Unfortunately even with that enabled I couldn’t make that work.

If you then press F10 and boot, when you run
sudo dmesg | grep 'ACPI: PM'

S3 should be in the list of supported options.

There are more options there Modern StandBy + S0i2x and a few more. I couldn’t get it work with any of that. At some point I thought to change it to S3 and reinstall but I am not sure that will help also.

I do not have the errors you have though… the ones for the i2c devices but the problem with the power cord and lid while sleeping still persist and is very annoying.

If you decide to play with the options anywhere else there is a chance to block your further access to BIOS. To Fix that you need to upgrade the BIOS to next available version or before making any other changes enable the Allow BIOS Back flash option before save. If you forgot and make it inaccessible there is still a way to back flash it through windows. Let’s hope you will not need that, but if you do ping me I will share the steps with you.

@megavolt, @Droses if you guys find any way to work around that issue it will be greatly appreciated to share with me. I am using this as my daily driver and not able to sleep it without worrying if it is going to wake is not OK.

Because of that issue my LUKS partition got broke once and It took me 3-4 days to recover it without any data loss.

Now I am shutting down every time I need to go from home to office and vice versa.

But on every shut down I need to wait for 2 minutes to start because of the Mediatek mt7922 module which is not started properly on boot.

This sounds pretty similar to the issue I had which was solved by a thread on the arch linux forums titled “Lenovo notebook uses function keys to cause system shutdown”

Summary of that thread: blacklist ideapad_laptop. This should fix the sleep issue but it will cause some fn keys to not work, including the brightness keys. To at least get the brightness keys working, boot with the dedicated graphics card enabled once. You can disable it again after that if you want.

Wow blacklisting ideapad_laptop actually solved my power issues. I had no problem with the Fn keys. I do have another module called legion_laptop which I am not sure where it came from. I’ve installed a 3rd party package lenovolegionlinux that adds some fan control and fine tunings, maybe this is its source. I hadn’t checked that. Thanks for the hint that saved me.

Thank you for your suggestion. These days I have been overwhelmed with work, but I will try it when I can afford to tinker with it (meaning if I have time to repair any mistake I may make).

Thanks! It worked for me. One down, two, to go (the audio issue that should be fixed in the next kernel update and the absence of S3 state which might be solved by @yaggul suggestion), and then I might have a fully working laptop.
