--- Comment #73 from Jan Hoffmann <jan.christian.hoffm...@gmail.com> --- This problem exists on a NP540U3C, as well. When the system is in this "broken state" the same problems appear on Windows 8, too. Probably this is because I did a fresh install and only installed the Samsung drivers that were needed when the system was not in the "working state". So, apparently, this bug does happen using the standard Windows ACPI implementation, as well, but on the preinstalled system there must be some Samsung specific driver to "fix" this. Another thing I noticed: On Windows, the power supply state gets updated when I click on the battery icon. Now, back to Linux: The problem seems to be that there is no system control interrupt (SCI) when the power supply is plugged in or out. I checked this by looking at /sys/firmware/acpi/interrupts/sci before and after connecting / disconnecting it. That also explains the behaviour on Windows, as it seems to poll the value independently of a SCI when you click on the battery icon What I don't know, is whether it is possible to cause the system to switch from "working" to "broken state" independently of the operating system. But I can't try that right now, as it would mean using Windows only for some time. -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ Get your SQL database under version control now!
