--- Comment #14 from Lorenzo Masellis <masel...@fastwebnet.it> 2010-12-16 07:35:55 --- That's correct. This laptop uses the "Smart Battery Subsystem" (see section 10.1 of the ACPI Spec.), which is correctly listed in the DSDT as ACPI0002 inside the Smart Battery Host Controller clause (ACPI0001), which in turn is inside the Embedded Controller clause (PNP0C09). Thus it is perfectly correct not to have any "Control Method Battery" (see section 10 of the ACPI spec: "A battery device is required to either have a Smart Battery subsystem or a Control Method Battery interface"). By the way, the Smart Battery Subsystem is supported by the sbs module of the kernel. This is exactly the reason of my frustration (and as I can see from my searches, also a lot of other users of laptops with SBS, especially from Acer, are experiencing the same): after long waiting, Debian Etch with kernel 2.4.18 was supporting correctly the SBS but this support soon became buggy in the next release, with kernel 2.6.26, and so remains today. Something must have happened in between, and since this problem seems to apply only to laptops with SBS I suspect the reason could be found somewhere in sbs.c, sbshc.c or sbshc.h. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
