[Bug 1283589] Re: [Samsung NP530U3C-A01] LID close, AC, and battery status events not produced anymore
@andrea-lazzarotto
To be fair it does say "One defect, per person, per hardware, per report" at https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue.
The 'One defect, per person' is obviously stupid when there's >100 of us
with the same hardware and same problem, opening 100 bugs isn't going to
help anyone. But I wouldn't make it personal against the guy if he's
just a volunteer enforcing Canonical's rules.

Title:
[Samsung NP530U3C-A01] LID close, AC, and battery status events not
produced anymore
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
On my Samsung Series 5 NP530U3C-A01 the LID close, AC, and battery
status events not produced anymore. The situation is the same (tested
with trusty-desktop-amd64.iso 2014-02-22). I created a blog post where
I can put all the information related to this bug here:
http://zenstep.com.ar/samsung-linux/
In summary, after a suspend sleep with many events (8 plug/unplug, or
battery dropping or increasing about 16%, maybe less), the Embedded
Controller accumulates those events and stops producing GPE 0x17.
Neither Windows nor Linux query those accumulated events, because the
EC doesn't produce GPE 0x17 anymore. The issue persists between
restarts and shutdowns, and even after re-suspending/re-resuming.
Hitting the reset button through the hole in the back fixes the
problem temporarily. That is, until the next unlucky suspend.
IMPORTANT: if the laptop is never ever suspended, the issue never
comes back.
To force the issue to happen, you can either:
1) Sleep the computer in linux (by closing the lid or any other means).
2) Unplug from the wall, plug, unplug, plug, unplug, plug, unplug, plug (8 actions or more).
3) Resume from sleep. You'll note that the battery icon is fixed, and unplugging or plugging doesn't update battery status anymore. Also note that the ability to suspend by closing the LID is lost.
4) echo disable > /sys/firmware/acpi/interrupts/gpe17
plug, unplug, plug, unplug, plug, unplug, plug, unplug (8 actions)
echo enable > /sys/firmware/acpi/interrupts/gpe17
WORKAROUND: Turn off the computer, unplug it, hit the reset button in
the back of the laptop, and then plug it again.
