[Bug 838543] Re: False battery warning +suspend

 

I have the same issue, but the warning+suspend happens only when I
resume from suspend.

Maybe this bug is related with Question #175179.

I have the problem on 2 laptops (Dell 6510 end Dell 6520). One shows two
batteries, and the other one (6520) shows 3 batteries. There is only one
battery on each laptop.

Title:
  False battery warning +suspend

Status in “gnome-settings-daemon” package in Ubuntu:
  Incomplete

Bug description:
  I pulled the plug on my laptop with it's battery full:

  ubuntu@ubuntu:~$ cat /proc/acpi/battery/BAT1/state
  present:                 yes
  capacity state:          ok
  charging state:          charged
  present rate:            0 mA
  remaining capacity:      7200 mAh
  present voltage:         11100 mV
  ubuntu@ubuntu:~$ ubuntu-bug -w
  ubuntu@ubuntu:~$ cat /proc/acpi/battery/BAT1/info
  present:                 yes
  design capacity:         7200 mAh
  [...]

  And suddenly got a dialog saying that it was critically low (while the
  icon top-left appears, properly, as full) and the laptop did suspend
  shortly after that.
