Ubuntu – Hibernate/suspend on critical battery level – where should I set it from MATE GUI

16.04batteryhibernatematesuspend

I have bought new battery for my laptop. It is running Ubuntu MATE 16.04.5 LTS.

This new battery have normal capacity, charging and provides long life 🙂

But I have small problem: when battery level goes under some level – the laptop shutdowns immediately. I remember, that it normally went to the suspend with old battery.

With new battery I can suspend manually and all suspend-related tests (such as pm-is-supported --suspend, pm-is-supported --hibernate, pm-is-supported --suspend-hybrid) returns 0, so these actions are supported.

For more predictive results I have reseted all settings with

gsettings reset-recursively org.mate.power-manager

So my GSettings reports the following:

$ gsettings list-recursively | egrep "critical|action|low|time" | grep -i power | sort -u
org.mate.power-manager action-critical-battery 'hibernate'
org.mate.power-manager action-critical-ups 'shutdown'
org.mate.power-manager action-low-ups 'hibernate'
org.mate.power-manager action-sleep-type-ac 'suspend'
org.mate.power-manager action-sleep-type-battery 'hibernate'
org.mate.power-manager idle-dim-time 10
org.mate.power-manager info-history-time 21600
org.mate.power-manager notify-low-capacity true
org.mate.power-manager notify-low-power true
org.mate.power-manager percentage-action 2
org.mate.power-manager percentage-critical 3
org.mate.power-manager percentage-low 10
org.mate.power-manager show-actions true
org.mate.power-manager time-action 120
org.mate.power-manager time-critical 300
org.mate.power-manager time-low 1200
org.mate.power-manager use-time-for-policy true

In /etc/UPower/UPower.conf I have default values:

$ cat /etc/UPower/UPower.conf | grep -v ^# | egrep "Critical|Low|Action|Time"
PercentageLow=10
PercentageCritical=3
PercentageAction=2
TimeLow=1200
TimeCritical=300
TimeAction=120
CriticalPowerAction=HybridSleep

The MATE Power Management Preferences (mate-power-preferences) does not have GUI element to set critical battery level:

Where should I set critical battery level for hibernate or suspend from MATE GUI?
Will changing value via GSettings or Dconf change value in UPower.conf?
Where else should I set the action on critical battery level?

Updates:
1. Laptop model is Asustek UX32A.

GUI method

From: Change Critical Battery Level and Action in Linux Mint 18 Cinnamon you can install dconf-editor using:

$ sudo apt-get install dconf-editor

Then go to org -> cinnamon -> settings-daemon -> plugins -> power

Default settings are (in %):
Critical battery action: hibernate
Critical: 2
Action: 2
Low: 10

Exercise caution and tweak to your heart’s content ?

Original Answer and edits below

Review your current settings with:

$ gsettings list-recursively | grep critical
org.gnome.settings-daemon.plugins.power critical-battery-action 'shutdown'
org.gnome.settings-daemon.plugins.power percentage-critical 3
org.gnome.settings-daemon.plugins.power time-critical 300

Change your `critical-battery-action`

$ gsettings set org.gnome.settings-daemon.plugins.power critical-battery-action 'suspend'

Linux Mate differences

When using Linux Mate you need to substitute org.gnome with org.mate and possibly change your keys. From ArchWiki:

Battery discharge

To disable the notification on battery discharge, run:

$ gsettings set org.mate.power-manager.notify-discharging false

However in Ubuntu there is no equivalent.

Find all Mate power settings

To find all Mate power settings use:

$ gsettings list-recursively | grep power-manager

In Ubuntu you would use:

$ gsettings list-recursively | grep plugins.power

Ubuntu – Won’t Hibernate when Battery Critical

I found another solution for my Ubuntu 14.04 system. Maybe it works for you.

First, install laptop-mode-tools

sudo apt-get install laptop-mode-tools

Then, you must enable the auto-hibernate function. You must edit a text file:

sudo gedit /etc/laptop-mode/conf.d/auto-hibernate.conf

There, look for ENABLE_AUTO_HIBERNATION parameter and replace the 0 with a 1:

ENABLE_AUTO_HIBERNATION=1

In the same file, you also want to adjust the battery charge percentage when the computer hibernates. For example:

AUTO_HIBERNATION_BATTERY_CHARGE_PERCENT=3

Save the file and test the configuration letting your battery discharge. If it works, you must set laptop-mode-tools as default, by creating a script:

sudo touch /etc/pm/sleep.d/10-laptop-mode-tools
sudo chmod a+x /etc/pm/sleep.d/10-laptop-mode-tools
sudo gedit /etc/pm/sleep.d/10-laptop-mode-tools

Then, in gedit, copy and paste this:

case $1 in
    hibernate)
        /etc/init.d/laptop-mode stop
        ;;
    suspend)
        /etc/init.d/laptop-mode stop
        ;;
    thaw)
        /etc/init.d/laptop-mode start
        ;;
    resume)
        /etc/init.d/laptop-mode start
        ;;
    *)
        echo Something is not right.
        ;;
esac

Save the file, then restart the system and test again. I hope that it works for you.

In my opinion, it looks like something is interfering with the the gnome-power-manager. If someone else reproduces the problem, then we can report a bug.

Re: Getting Ubuntu to automatically suspend on battery low (command-line) by Isamu715 http://ubuntuforums.org/showthread.php?t=2092327&p=12394451#post12394451

Ubuntu – Battery life starts at 2:30 hrs (99%), but less than 1 minute later is only 1:30 hrs (99%)

Your battery is shot and needs replaced:

energy-full: 21.1248 Wh
energy-full-design: 48.6 Wh
capacity: 43.4667%

This shows the battery is holding less than half of its design capacity.

voltage: 12.173 V

This is also off; the fully charged voltage should be 12.5 V.
