[Bug 1283589] Re: [Samsung NP530U3C-A01] LID close, AC, and battery status events not produced anymore
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

Back to the Samsung NP530U3C Ultrabook in my previous posts... resetting the BIOS settimgs to their defaults has no effect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 971061] Re: acpi reports battery state incorrectly
Now you mention it Marcello... I also erroneously started up the recovery partition and had to sort our the MBR and Grub afterwards. I don't recall having these issues before doing this. I'm not sure this caused the issue though since others posting here haven't mentioned it. With hindsight, I wish I had only run windows for a few days (torture I know - it is only there for those rare occasions and runs LibreOffice, Firefox and Thunderbird) without booting into Ubuntu to see how things faired. Then I could have been a little more suspicious that Ubuntu somewhow causes the problem. After updating the BIOS I noticed that the BIOS setting for only charging the battery to 80% had been disabled (it was enabled before). Maybe resetting the BIOS to default values mught re-instate normal behaviour for a period. I'm not in a position to try it right now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 971061] Re: acpi reports battery state incorrectly
After BIOS update all was well for 15hours only! Yesterday, after updating the BIOS I tested power connect/disconnect recognition in both Windows and Ubuntu 12.04 and suspend on lid closure. Everything worked fine. Then, in Ubuntu 12.04, I suspended the system over night. Next morning, lid closurefails to be recognised by Ubuntu. Power connect/disconnect fails to be acted upon properly by Ubuntu. In Windows, lid closure still fails but power connect/disconnect still recognised - but it takes several seconds rather than being almost instantaneous when all was well the night before. Very infuriating!... is this Ubuntu corrupting things in the BIOS or is the BIOS somehow corrupting itself with respect to ACPI. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for the link Erik. It seems that there are at least two ways of searching Samsung UK's web site and one of them (the one I used yesterday) does not admit to the existence of the NP530U3C. Anyway, I updated the BIOS to P06AAJ from P02AAJ and all failing functionality detailed in my previous post seems to have now been restored. Given the previous comments in this forum it will be interesting to see how long it remains good. Interestingly the BIOS update filename was ITEM_20120928_714_WIN_P06AAJ.exe so, assuming this means 28th September 2012, it is very new. Hopefully there might be some fixes in here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have exactly the same issue with a Samsung NP530U3C-A01UK Ultrabook running Ubuntu 12.04 dual booting with Windows. In addition I have noticed the following (possibly related) behaviour: 1) Occasionally Wireless networking cannot see any wireless networks when booting eitherinto Windows or Ubuntu. 2) Laptop no longer goes into suspend upon closing the lid - both Windows and Ubuntu exhibit this even though both are configured to suspend on lid closure. All of this worked perfectly in both OSes for the first few days. I am running BIOS version P02AAJ which is what came installed from the factory. I would try updating it if I could find the NP530U3C listed on Samsung's support pages :-( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/971061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
