If I disconnect power, remove the back cover, disconnect both the main battery and the backup battery, I am able to get power status updates (e.g. battery will show as charging/charged when plugged in, or just regular battery when not). Once I sleep, I have to repeat this process if I want the battery status to work again. `acpi -p` correctly shows the charging state, but `tlp-stat -b` does not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283589 Title: [Samsung NP530U3C-A01] LID close, AC, and battery status events not produced anymore To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1283589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

juanmanuel, No matter who found the latest/better solution, you are truly a hero. After reading all the associated bug reports, I decided to use your script because I don't know how to compile the kernel, and I presume I would have to redo it every time the kernel got an update.

This is a NEW and BETTER patch created by Kieran Clancy on the kernel bugzilla to do the same that my workaround did, but in a more proper way, and from the kernel: https://bugzilla.kernel.org/show_bug.cgi?id=44161#c149 I also tested it this weekend, and it works (I forced the issue to happen again, and then saw it being resolved automatically by a kernel compiled with this patch). The most salient advantage over the previous patch is that it also unstucks the EC when the computer starts (in addition to sleep resume). This is more fool proof and suits more use cases. It also checks the laptop model. Lets hope more people test this patch so that it can be included some day in the kernel. ** Patch added: BETTER_ec_kernel_patch.patch https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283589/+attachment/3994501/+files/BETTER_ec_kernel_patch.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283589 Title: [Samsung NP530U3C-A01] LID close, AC, and battery status events not produced anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Joseph: The best kernel patch so far was made by Kieran Clancy (see post #18 here). His patch is attached to a kernel bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=44161 in comment 149. I'm just the author of the userspace workaround (post #3, #4, #14) that started it all (see the other issue here https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061 comments 102 onwards) . It is a standalone program that unstucks the EC. On the other hand, Kieran's kernel patch now does the same in a cleaner way from inside the kernel. In my humble opinion, Kieran Clancy's patch can be included in the kernel. I don't know whether Kieran will submit it.

UPDATED v2: Safer because it obtains the EC ports automatically from /proc/ioports, and it micro-pauses between queries, so that the EC returns each event only once. This replaces the little program in #3. This is the program I made, that unstucks the computer so that it can send LID and AC and Battery events again. (it queries the embedded controller queued events, thus unblocking the EC so that it can start sending them again).

@tkedwards Only that rule was made to prevent multiple bugs being cluttered together in one bug report, not to be taken literally as a means of filling the bug system with hundreds of useless duplicates, and I quote: Don't amalgamate every issue and hardware you find a problem in after an update... Instead, do a separate report for each distinct issue, on each hardware. This is how different hardware can have similar problematic symptoms (ex. computer won't boot), but different root causes, and patches that fix the different causes. Obviously this doesn't mean that every affected user should file a separate report for a common problem - otherwise what's the point of having the this affects me too on the top. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283589 Title: [Samsung NP530U3C-A01] LID close, AC, and battery status events not produced anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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.

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.

[Bug 1283589] Re: [Samsung NP530U3C-A01] LID close, AC, and battery status events not produced anymore
Christopher: you changed my description of the bug, and in doing so, confused the two different ways to force the issue to show up. You listed the second way as a fourth item of the first way, when it is a different way. Take a look at the original description. -- Juan Manuel Cabo -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283589 Title: [Samsung NP530U3C-A01] LID close, AC, and battery status events not produced anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
