erikj, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux 971061

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.14-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  acpi reports battery state incorrectly

Status in The Linux Kernel:
  Incomplete
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a new Samsung 9-series laptop (NP900X3B) and the battery state
  is detected incorrectly. Basically the state what was at the time of
  boot stays active all the time - regardless of the ac-adapter state.

  Here is output from "acpitool -a -b" in various situations:

  When booted with charger connected and charger is still connected:
    Battery #1     : charging, 47.00%, 01:00:43
    AC adapter     : on-line 
   
  When booted with charger connected and charger is now disconnected:
    Battery #1     : charging, 47.00%, 01:36:59
    AC adapter     : off-line 
  [The battery couldn't possibly be charging when the AC adapter is offline!]

  When booted with charger disconnected and charger is still disconnected:
    Battery #1     : discharging, 47.00%, 01:39:44
    AC adapter     : off-line 

  When booted with charger disconnected and charger is now connected:
    Battery #1     : discharging, 47.00%, 00:53:43
    AC adapter     : on-line 
  [The battery is actually charging as the AC adapter is online]

  The percentage and time are correctly updated when the battery is
  actually charging or discharging - regardless of the reported state.
  So the state is the only thing that is incorrect. However a number of
  applications make their decisions based on this state (battery
  monitor, jupiter, etc.) and therefore behave incorrectly.

  "lshal -m" doesn't report anything when I plug the charger in or out.
