% de co_de% relevante provavelmente se aplica apenas à bateria principal. ou seja, eu ficaria surpreso se o laptop fosse suspenso enquanto a bateria principal estivesse a 100%, mas a bateria do mouse falisse:

$ gsettings get org.gnome.settings-daemon.plugins.power percentage-critical
3
$ gsettings get org.gnome.settings-daemon.plugins.power percentage-action
2
$ gsettings get org.gnome.settings-daemon.plugins.power use-time-for-policy
