As the original reporter I want to apologise to all of the affected
people here - I was not aware that my comment that I don't own the
hardware anymore will result in the bug being closed as "won't fix".

Hopefully the patch will make it to the kernel and the fix will reach
Ubuntu anyway.

If not then I can offer this: If anyone with the NP900X3B laptop is
willing to test actually the latest builds mentioned in Christopher M.
Penalver comment #139 then I can claim to the Ubuntu folks that I
reclaimed my laptop from my daughter and confirm the bug again. ;-)

Regards,
Erik

Title:
  acpi reports battery state incorrectly

Status in “linux” package in Ubuntu:
  Won't Fix

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.
