Bug#652898: gnome-power-manager: battery energy level incorrectly reported once fully charged

[Klaus Doering]

Package: gnome-power-manager
Version: 3.2.1-2
Severity: normal

Dear Maintainer,

Although I don't know when it started, in at least the latest two
versions (3.0.1 and 3.2.1) of g-p-m the battery charge level isn't
reported correctly for one particular state on my Acer Timeline
Travelmate laptop.

When the battery is present, and the AC adaptor charges it, the charge
level resets to 0% upon reaching "fully charged". Contrasting this, during the charging
the levels are reported properly, so you can see how it slowly
approaches 100%, and then it jumps back to 0%. Disconnecting the AC
adaptor now, i.e. running off the battery, reverts to the charge state
being show as 100%, slowly decreasing as expected.

Checking the reported figures in
"/sys/class/power_supply/BAT0/charge_now", I see the same problem:
while the AC adaptor is plugged in, the charge is shown as "-1000",
but when I unplug it, the level goes to "5215000" (with "charge_full"
being "5233000" and "charge_full_design" "5600000" ).


Secondly -- should this go into it's own bug report? -- after
upgrading from 3.0.1 to 3.2.1 today, I cannot access the detailed
power report anymore (charging graphs, statistics, etc.)
Pity that, since I only just discovered this rather neat feature ;-)

Kind regards
Klaus
