Description Michael Biebl 2009-10-21 16:49:07 UTC

When I unplug AC, I get a warning from g-p-m that I only have 3 min. remaining time left, although my battery is fully charged and usually lasts for ~2-3h.

As you can see from the attached log, it takes a few seconds, until dk-power reports plausible values for remaining time.

I'm not sure what the best course of action here is. Usually introducing heuristics causes more issues that working out why the hardware / kernel reports invalid values.

Maybe the heuristic can be as simple as simply waiting for 10 to 30 secs after unplug before reading the values and just use the old values from before the unplug for that time frame

Closing as fixed as per bug 27399. Reopen if you still see the problem with UPower 0.9.23.
