Waking up from 

$ sudo pm-suspend

results in anomalous behaviour depending on whether the laptop in connected to external power.

The following scenarios have been tested to be reproducible:

  1. Suspend while on AC power, wake up. Result: normal resumption.
  2. Suspend while on battery power, wake up. Result: full restart.
  3. Suspend while on AC power, disconnect AC power, wake up. Result: full restart.
  4. Suspend while on AC power, disconnect AC power, reconnect AC power, wake up. Result: full restart.
  5. Suspend while on battery power, connect AC power, wake up. Result: full restart.

EDIT 1: the 'full restart' does not follow a clean shut down, as evidenced by fsck running during start up, etc. I don't believe this is intended behaviour.

Can you, kind Internet, please help diagnose this problem?

Basic debug information is below. Please let me know what further debug information I can provide.

System: Ubuntu 16.04 LTS
Machine: Asus K501UX
Video Driver: xserver-xorg-video-nouveau
Video Card: NVIDIA GeForce GTX 950M

(Using proprietary nvidia drivers results in a blank screen after the driver is loaded.)

Screenshots of Brightness settings and Power settings.

Two more bits of info:

  1. This problem did not used to exist. It is unclear to me what caused its onset. Loading Linux kernel version 4.2.0-27 (oldest I have installed currently) does not solve the problem.

  2. I don't suspect it is an issue with the suspend process initiated by pm-suspend, but rather to do with some power settings (acpi, etc). I have attached the log (/var/log/pm-suspend.log.1) for one instance of CASE 1 above. For all other cases, the log is identical (modulo timestamps, etc) down to the line

    Wed Feb 15 22:38:12 EST 2017: performing suspend

    , and the rest of the log is missing, i.e. the machine never comes 'awake', but rather restarts.

  • Are you sure this isn't the intended behavior of whatever power manager you're using? Shutting down the computer if at any point AC is unavailable seems like a plausible behavior. – Catherine Holloway Feb 16 '17 at 20:08
  • What does your power.d file look like? – Catherine Holloway Feb 16 '17 at 20:10
  • @CatherineHolloway I don't believe it is intended behaviour b/c 1. the restart doesn't follow a clean shut down, and 2. this behavior didn't used to occur, and takes a away useful functionality. /etc/pm/power.d is an empty directory. /usr/lib/pm-utils/power.d contains the following files. Which one should I post? 95hdparm-apm disable_wol laptop-mode pcie_aspm sched-powersave wireless anacron intel-audio-powersave pci_devices sata_alpm usb_bluetooth xfs_buffer – Kaveh Gharavi Feb 16 '17 at 20:23

I had similar problem. Everything was fine but suddenly, when I suspended my laptop (buy closing the lid or via menu), it was going to sleep mode with led blinking, but when I woke the laptop, it restarted as it was shutdown.

Laptop ASUS ZenBook UX305

Linux 4.13.0-38-generic #43~16.04.1-Ubuntu SMP x86_64

I tried many things, and no result, but one time I switch to TTY1 with Ctrl+Alt+F1 and logged in, and exited. After that it is working again.

Also I set the following setting in "sudo vim /etc/default/grub" :

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_sleep=nonvs intel_pstate=disable"

but it was not working before TTY1.

The things that was changing before the problem was :

  • I forgot my charger, and I used a different charger, the original is 19 volts but the one I used was 20 volts.
  • One time the laptop hanged during suspend process, so I did hard restart by pressing and holding the power button.
  • Recently, I updated the system with "Software Updater"

I thought it might help some one.

  • this helped me. when I tried `sudo vim /etc/default/grub` the system alerted me that there is .swp file ( like it was editing by some other app which might be exited un-expectedly ) and there was an option to recover. I recovered it. Then I did TTY1 login and exit. Then I restarted. After that I could go to suspend and back normally. – karianpour Dec 02 '18 at 14:31
  • It happened again for me, and this time I this process did not work until I shutdown (no restart) and unplugged from AC and plugged again and started. Then it could wake from sleep mode. – karianpour Feb 15 '19 at 06:34

I ran down a similar problem. Everything was fine but suddenly, I was not able to suspend my laptop via closing the lid. So every time I had to suspend it using the menu, but waking it up doesn't work, it always requires a restart.

Laptop: Dell Inspiron 15-3567
kernel: 5.4.0-42-generic x64_86

I tried various things what worked for me was changing the file

sudo nano /etc/default/grub

changing the line to this

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

  • To clarify, acpi_backlight=vendor is the important kernel option here, right? B/c quite and splash are commonly used. – Kaveh Gharavi Aug 28 '20 at 15:12

    acpi_backlight= [HW,ACPI] { vendor | video | native | none }, If set to vendor, prefer vendor-specific driver (e.g. thinkpad_acpi, sony_acpi, etc.) instead of the ACPI video.ko driver. If set to video, use the ACPI video.ko driver. If set to native, use the device's native backlight mode. If set to none, disable the ACPI backlight interface. Since I was facing the brightness issue too I tried to switch drivers to vendor-specific driver, which did the job. – Chirag Gandhi Aug 28 '20 at 22:20

Potential solution: I suspected this behaviour is brought about by the power manager. Using dconf-editor, changing the schema

org.gnome.settings-daemon.plugins.power.critical-battery-action

from 'shut down' to 'suspend' appears to have served as a potential solution/workaround. Wake-up from all of the cases above result in normal resumption, as far as my experimentation can tell.

I suspect interruption of the AC power results in an erroneous 'battery critical' message from the on-board controller, for an unknown reason. It is possible that due to degradation of the battery over time, the voltage drops below a certain threshold just as the AC power is removed before recovering to an acceptable value.

    Not sure why you got downvoted. But i can confirm there is something to your answer. My laptop does this ONLY when the cpu frequency governor is set to powersave (and using pstate). If im using the performance governor (or connecting the charger before waking the laptop), i dont have this issue. – Bruce Jan 03 '19 at 18:14
  • If you please clarify how you modify the state of the cpu gov., I'll see if I can reproduce this. (Two years after the original question, I still haven't found a satisfactory explanation.) – Kaveh Gharavi Jan 07 '19 at 00:55

    Sorry for the delay. I use cpupower on the command line. Just running "cpupower frequency-info" you will get the current state, and in my case, i just change it manually. I switch to performance using "cpupower frequency-set -g performance" most of the time, and change it to powersave to maximize battery power. (havent gotten around trying using old frequency scaling yet) – Bruce Jan 24 '19 at 18:08
  • Thanks for the detailed info! I have determined that my issue is independent of the cpu frequency governor state. *sigh* – Kaveh Gharavi Feb 09 '19 at 12:13
