Description kero 2012-09-22 19:54:33 UTC
As stated: in Powerdevil, under "Advanced Settings", i set it to shutdown completely the laptop, when the battery level becomes critical, but the shutdown does not work, nothing happens and the battery level still lowers.

Note 1: when I set it to suspend2ram or suspend2disk, it does works. It's only the shutdown which does not work.
Note 2: the same problem, even when I change the treshold for battery critical level (I tried 5%, 15, 20% ...).

Reproducible: Always

Steps to Reproduce:
1.Set the system to shutdown on critical battery, in advanced settings
2.Set the critical battery level (eg. 5%)
Actual Results:  
Does not shutdown.

Expected Results:  

- netbook: Acer Aspire One 756 (Celeron 877, 4Go Ram, Intel Chipset)
- distro: Archlinux, uptodate (x86_64), with KDE 4.9.1

I can reproduce this in 4.10
Comment 2 Kai Uwe Broulik 2013-03-20 21:25:14 UTC
Problem lies in:
Powerdevilcore passes PowerDevilSettings::batteryCriticalAction() which is 3 for shutdown.
In the SuspendAction (which is eventually triggered after dozens of roundtrips), however, it checks for  "Mode" which has ShutdownMode = 8
3 != 8 and this is why shutdown doesn't work. ToRamMode is 1 and ToDiskMode is 2 which matches the number in powerdevilcore.
Comment 3 Oliver Henshaw 2013-04-02 16:07:52 UTC
Good find - looks like battery critical actions weren't ported in 0189a3a49142731db37db69b83fa5e49a85f84c9

Ideally we'd be using the SuspendSession::Mode enum everywhere rather than magic numbers.

powerdevil: Do not use magic numbers for configuration.

People affected by 307228 might need to change their configuration.

This problem was not fixed for me in 4.11.0.
Comment 6 Kai Uwe Broulik 2013-08-22 09:49:26 UTC
Did you configure the action again? ie. change it to another, apply, and change it back and apply?

    enum Mode {
        None = 0,
        ToRamMode = 1,
        ToDiskMode = 2,
        SuspendHybridMode = 4,
        ShutdownMode = 8,
        LogoutDialogMode = 16,
        LockScreenMode = 32,
        TurnOffScreenMode = 64

ShutdownMode == 8


bool Core::emitBatteryChargePercentNotification(int currentPercent, int previousPercent)
    if (m_backend->acAdapterState() == BackendInterface::Plugged) {
        return false;

    if (currentPercent <= PowerDevilSettings::batteryCriticalLevel() &&
        previousPercent > PowerDevilSettings::batteryCriticalLevel()) {
        switch (PowerDevilSettings::batteryCriticalAction()) {
        case 3:
            emitRichNotification("criticalbattery", i18n("Battery Critical (%1% Remaining)", currentPercent),
                             i18n("Your battery level is critical, the computer will be halted in 30 seconds."));
Comment 9 Alex Levkovich 2013-08-24 05:28:26 UTC
it should be case 8 or PowerDevil::BundledActions::SuspendSession::ShutdownMode. Am I right?
Comment 10 Christoph Feck 2013-08-25 11:08:30 UTC
Reopening based on comment #5. See also bug 323992.

Comment 12 Weng Xuetian 2013-09-01 06:39:03 UTC
Hi, Alex, I committed your patch.. though I typed the wrong bug number commit message..

4.11.1 is already tagged yesterday so it will be included in 4.11.2 I guess.

Comment 13 JimmySaville 2015-02-25 23:28:25 UTC
Sorry to dig up old thread but having issues with power management
machine will not shutdown or suspend on critical
critical at 60% have changed etc.
if below critical level at startup will boot so far then shutdown (during startup)
thats the only time critical shutdown/suspend works
killed battery in 3 months

Kubuntu 14.04
KDE 4.13.3
kernel 3.13.0-46

please let me know what logs etc I can provide
thanks in advance
