waking up from pm-suspend results in full restart

Question

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

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

Answer 1

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.

Answer 2

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"
