Upon, pulling the plug from the wall on my older Toshiba Satellite (which has a new-ish battery) both xfce4 and apm agree while reporting declining battery power down to about 85% then both fall off a cliff and immediately indicate 8% and start warning about imminent battery exhaustion.
85% to 8% in the blink of an eye. And nothing in between. If I plug it back in, let it charge for a 10 minutes, it will be back up around 24%. If I again unplug, it will drop roughly in a linear fashion. with no sudden drops. This seems like a bug in what ever apm and xfce4 use to obtain readings. Any clue where I should start looking for this? -- Those who do not understand Unix are condemned to reinvent it, poorly.
