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.
