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.
