[SOLVED] Lenovo Thinkpad T440s resumes by itself from suspend

senjin · 2014-12-11 13:16:00

When I suspend the computer, sometimes, after some random time it resumes, without any action from my side. I failed to correlate this with any activity. It happens when the computer lays on the table, or when it is in my backpack, or any other time. I'm actually quite impressed it still has not fried when running in my backpack.

I tried to disable all acpi resume signals:

# cat /proc/acpi/wakeup 
Device	S-state	  Status   Sysfs node
LID	  S4	*disabled  platform:PNP0C0D:00
SLPB	  S3	*disabled  platform:PNP0C0E:00
IGBE	  S4	*disabled  pci:0000:00:19.0
EXP2	  S4	*disabled  pci:0000:00:1c.1
XHCI	  S3	*disabled  pci:0000:00:14.0
EHC1	  S3	*disabled  pci:0000:00:1d.0

Now I can resume the system myself only by pressing the power button, but the problem of random resuming also occurs.

When I moved from kernel suspend (swsusp) to pm-utils suspend, the frequency of random resumes seemed to decrease, but it still happen often.

I tried to invoke

rfkill block wifi

each time I suspend (I was worried that these are some wifi signals waking up the computer) but this does not help.

I also disabled all things in BIOS that could possibly cause waking up the computer, but I'm clueless about some of the setting.

Probably the most frustrating is that in no logfile I can find clear message about what was the reason for wake up. I attach part of my journalctl output – maybe there is some clue I miss?

Is there any other information or logs I can provide to help to understand the problem?

Is Wake-on-LAN enabled in the firmware? You might also try updating the machine firmware (BIOS) as well.

I see you have disabled everything in /proc/acpi/wakeup, but have you also checked for stuff in /sys as well? Try running:

$ find /sys -name wakeup

Out of pure curiosity, with all those things disabled in /proc/acpi/wakeup, does the machine still wake from the Fn key?

senjin · 2014-12-14 20:11:47

Thanks for the reply!

I believe I disabled wake on LAN in BIOS. I verified that the BIOS version is not the newest, but I will wait until the Xmass break with the update, I don't want to mess up anything now.

With all things in /proc/acpi/wakeup the Fn does not wake my computer. Only the power button, and the mysterious random thing I investigate in this topic.

I checked the other stuff in /sys. Indeed, I found the following files to have "enabled" inside:

# for x in $(find /sys -name wakeup) ; do if [ "$(cat $x)" == "enabled" ]; then echo $x; fi; done
/sys/devices/pnp0/00:02/power/wakeup
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:08/PNP0C09:00/PNP0C0A:00/power/wakeup
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:08/PNP0C09:00/PNP0C0A:01/power/wakeup
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:08/PNP0C09:00/ACPI0003:00/power_supply/AC/power/wakeup
/sys/devices/LNXSYSTM:00/LNXPWRBN:00/power/wakeup
cat: /sys/kernel/debug/tracing/events/ftrace/wakeup: Is a directory

I don't know what these files stand for. Anyway I echoed "disabled" into all these 5 files. Interestingly, the system still wakes up with the power button. Now I need to test if the random wake-ups cease. As I wrote, this occurs randomly. Sometimes several times per day, sometimes once per several days. Thus I need a week or two to make sure this helped. I will come back with the results then.

Thanks for the help!

You can use udevadm to figure out what these things are. For example, this should tell you what that first one is:

$ udevadm info --attribute-walk --path=/sys/devices/pnp0/00:02

senjin · 2015-01-06 13:35:22

Since I echoed "disable" to all the "wakeup" files mentioned above the random wake up did not occur even once. Thus I believe the problem is solved. Thank you!

WonderWoofy · 2015-01-09 05:22:01

You should figure out which one it is, and write a simple udev rule to take care of this for you. But I'm glad you narrowed it down!
