This all started happening after upgrading to 13.10, now I am running 14.04 and still have the same issue.

When I close the lid or I do sudo pm-suspend the laptop goes into suspend for 2-5 seconds and awakes by itself.

Same happens if I try to do hibernate.

I have a gut feeling that something is awaking/taking the cpu out of suspend mode but I cannot figure out what.

Any help troubleshooting this annoying issue?


Thanks to @Fabian , I was able to figure out that it looks like the ethernet card is misbehaving and even after I set the card to not wake up on lan (either doing acpitool -W 3 or echo disabled > /sys/bus/pci/devices/0000:00:19.0/power/wakeup or echo IGBE > /proc/acpi/wakeup, the laptop keeps waking up and showing this when I do acpitool -w

Device  S-state   Status   Sysfs node
1. LID    S3    *enabled 
2. SLPB   S3    *disabled
3. IGBE   S4    *enabled   pci:0000:00:19.0
4. EXP1   S4    *disabled  pci:0000:00:1c.0
5. EXP2   S4    *disabled  pci:0000:00:1c.1
6. EXP3   S4    *disabled
7. EXP4   S4    *disabled
8. EXP5   S4    *disabled  pci:0000:00:1c.4
9. EHC1   S3    *disabled  pci:0000:00:1d.0
10. EHC2      S3    *disabled  pci:0000:00:1a.0
11. HDEF      S4    *disabled  pci:0000:00:1b.0

Any idea how to proceed from there?

The network driver that IGBE uses is e1000e

use dmesg to see the latest messages from the kernel, something there could give you a clue as to what's happening. –  roadmr Apr 18 '14 at 17:00
Have you disabled the Wake-On-Lan feature in the BIOS? –  Mitch Apr 29 '14 at 6:34
Yes, that was the first thing I tried. –  feniix Apr 29 '14 at 13:30

I have kernel 13.13 and Intel Z77X based motherboard, and following command works for me:

sudo sh -c "echo EHC1 > /proc/acpi/wakeup;echo EHC2 > /proc/acpi/wakeup;echo XHC > /proc/acpi/wakeup"

The following worked for me:

cat /proc/acpi/wakeup

Look for any items with status enabled that look like they don't belong there (for me, anything except LID0). Then disable them by saying, for example:

sudo echo XHC0 > /proc/acpi/wakeup

Check that the corresponding entries have indeed been disabled, send the laptop into suspend and hope for the best :)

Very good lead, now I need to find out why the integrated ethernet card keeps waking up even though I set the wake up mode for it to disabled –  feniix Apr 19 '14 at 16:46
Good luck with that :) –  Fabian Apr 19 '14 at 16:57
Have you tried rmmod the driver before suspending? (Just a shot in the dark) –  Rmano May 16 '14 at 5:04

here is how did enable hibernation on my dell insperion 15
enable hibernation on ubuntu 14.04

Although this is not exactly what I was looking for, at least with this I can put my laptop in a "non-power consumption state" so I am going to mark this as the correct answer. –  feniix Apr 30 '14 at 17:30
I would suggest writing out the answer as linking stuff can result in domains that are gone and info lost :/ –  shaneonabike Sep 6 '14 at 21:34

Experiencing exactly the same problem (ThinkPad T530, Ubuntu 14.04, but also 13.10 and 13.04, after couple of suspends, computer resumes immediately after suspend).

Disabling IBGE from wakeup did not help at all.

As suggested by Romano, I've tried removing the e1000e module, et voila suspend as expected.


sudo rmmod e1000e

prior to suspend resolves the issue.

Interestingly, the problem reappears immediately after installing the module back (sudo modprobe e1000e) and suspending without its removal. So, it must've been something related to hardware.

To automate it, I've created two simple suspend/wakeup scripts (tested on the above mentioned hardware, Ubuntu Trusty 14.04): sudo gedit /etc/pm/sleep.d/99_e1000e_remove :


# Remove e1000e kernel module prior to suspend
rmmod e1000e

and sudo gedit /etc/pm/power.d/99_e1000e_probe :


# Modprobe e1000e kernel module after resume
modprobe e1000e

Scripts should be executable (sudo chmod +x /etc/pm/sleep.d/99_e1000e_remove /etc/pm/power.d/99_e1000e_probe).


  • I assume the scripts are pretty safe to use even when it does not address your problem.
  • I'm not using LAN wakeup, so I don't know how it behaves with the fix.

The laptop has the same issue using windows (I just installed windows 7 for my wife in the computer because I got a new one) and it does exactly the same. So it may be hardware/firmware related –  feniix May 26 '14 at 22:30
Hi. I am using Ubuntu 14.04 LTS with a Thinkpad X201s. This solution removing e1000e with the little helper scripts helped getting suspend to work again. Thank you very much ! –  apos Aug 27 '14 at 14:32
