I found the workaround. Critical battery trigger has two modes: 'nothing' will ignore a seemingly critically low battery signal 'suspend' is the default which causes the computer to suspend upon receiving this erroneous signal
Check the current mode: $ gsettings get org.gnome.settings-daemon.plugins.power critical-battery-action Change the mode to do nothing $ sudo -s # cat > /usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.power.gschema.override << HERE [org.gnome.settings-daemon.plugins.power] critical-battery-action='nothing' HERE $ sudo glib-compile-schemas /usr/share/glib-2.0/schemas/ $ sudo dconf update $ rm -r ~/.config/dconf/user $ gsettings reset-recursively <schema> $ gconftool-2 --recursive-unset / ** Changed in: gnome-power-manager (Ubuntu) Status: Confirmed => Fix Released ** Changed in: gnome-power-manager (Ubuntu) Assignee: (unassigned) => David Bensimon (davidbensimon) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/487867 Title: No preference to enable/disable low battery alarm To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/487867/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
