I have a Samsung NP530U3C-A01 laptop and I can confirm this bug affects my laptop. After applying the workaround script from juanmanuel in #3 and #4 I re-tested and the problem no longer appears.
Thanks juanmanuel for writing the fix and being so patient with Ubuntu's ridiculous bug policies - just don't lose your laptop otherwise we'll have to start this whole bug report process again! -- 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
