Re: [Bug 971061] Re: acpi reports battery state incorrectly


   I am affected by this bug since, a couple of years (same laptop here,
530U). I have personally experienced it on my laptop on multiple Linux
distributions (including Debian and Arch).

I perfectly understand your policies, but I do not really see the
rationale behind closing the bug with WONTFIX and asking a lot of people
to open a lot of new bugs to signal the very same thing.

For me, the bug is indeed solved by the juanmanuel's userspace program
(thanks a lot!!!!!!!!!) I've been running that program since it was
posted on this thread, and it works like a charm.

The bug is also clearly described upstream on the kernel Bugzilla, where
juanmanuel's solution is being turned into a kernel patch, so an
upstream fix is likely to be on the way.

I hope you'll find a way to put in evidence the relevant information,
especially when there will be 100 opened issues for this SINGLE problem
(or 100 issues immediately closed as duplicates???): this is clearly a
SINGLE bug with a SINGLE reference to a SINGLE upstream issue.

>From my side, I am *not* going to open another bug just to increase the
Internet entropy (and reduce the likelihood for someone searching about
the problem to find the workaround)...

  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.
