I also have a Samsung NP-A530U3C-A01UK laptop that exhibits the same behaviour. Since applying the fix from juanmanul all is now well.
Many thanks juanmanual for identifying the cause for this long running issue and for working diligently to find the fix. -- 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
