--- Comment #29 from Sebastian Riemer <sebastian.rie...@profitbricks.com> 2012-10-30 16:52:43 --- It seems like everything related to the embedded controller "Device (H_EC)" doesn't work. "LID0" is connected to it and it should return the 1-bit value "LIDS" from the controller registers with method "_LID". This method is described in the ACPI spec: http://www.acpi.info/DOWNLOADS/ACPIspec50.pdf . The "_LID" method is only called by the following: "Notify (LID0, 0x80)" and this is part of "Method (_Q5E, 0, NotSerialized)" as well as "Method (_Q5F, 0, NotSerialized)" which are embedded controller queries. So if nothing queries that embedded controller, then it can't be reported if the lid is closed or not. It is the same for the power source "ADP1" and the battery "BAT1" as described in bug 44161. These are also connected to that EC. Perhaps, something has to activate that embedded controller first. It is the Intel HM76 chipset. http://www.intel.com/content/www/us/en/chipsets/performance-chipsets/mobile-chipset-hm76.html They have an OEM manual where they describe their embedded controller. http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/7-series-chipset-pch-datasheet.pdf Look at page 197. The EC is connected to the SMBus via "SMLink1". -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Everyone hates slow websites.
