[Bug 971061] Re: acpi reports battery state incorrectly

 

I am on an NP900X3C-A02UK with Ubuntu Gnome 13.10. The patch works for
me out of the box. Battery status report and suspend on lid closed work
now correctly. De todo corazón muchas gracias, juan manuel!

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.
