[Bug 838543] Re: False battery warning +suspend

 

Hi all,

I encountered this issue, too, and I would like to know if this patch help.
You can download the kernel packages from this link, this kernel will retry to get the battery inform after wakeup from S3.
Thanks.

  False battery warning +suspend

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.
