Folks, After a long period of suffering, I found that this issue was caused by a combination of hardware and software problems. Apparently my laptop had power related problems, which were resolved by a motherboard replacement. This fixed the main problem, but I was still having problems having ubuntu recognizing the lid actions (open/close). After some troubleshooting, I found that the crashplan daemon running in the background was causing it.
Here's a one-liner for checking the lid actions in case you have a similar problem: while true; do cat /proc/acpi/button/lid/LID0/state; sleep 1; done If you don't see "close" when you close the lid, then you might like to check for running processes, starting with crashplan. I tried to mark this case as solved, but I can only see "fix committed/released" options. How can we properly close this case? Thank you all from Canonical and Ubuntu community for your valuable help and feedback! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1210361 Title: [Samsung NP540U3C-A01UB] Incorrect battery/power status and missing /proc/acpi/battery To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1210361/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
