I have the same problem with a Samsung R730 laptop. Sometimes it works well, other times it doesn't. I can't find a pattern though, just boot and shut down immediately sometimes causes the effect already of not switching of the power. The latest info in the syslog file, when the laptop did not shutdown is this:
Sep 11 16:31:45 R-730-Linux nmbd[2027]: [2011/09/11 16:31:45.421651, 0] nmbd/nmbd.c:71(terminate) Sep 11 16:31:45 R-730-Linux nmbd[2027]: Got SIGTERM: going down... Sep 11 16:31:45 R-730-Linux kernel: Kernel logging (proc) stopped. Sep 11 16:31:45 R-730-Linux rsyslogd: [origin software="rsyslogd" swVersion="4.6.4" x-pid="885" x-info="http://www.rsyslog.com";] exiting on signal 15. Hope this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762203 Title: Computer is not turned off at shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/762203/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
