Note OSYS gets set to 0x07DF this bit of DSDT code: If (_OSI ("Windows 2015")) { OSYS =3D 0x07DF } Which should run early on, but on the 1842039 this for some reason is not working. For some more background info, Linux will answer true for _OSI ("Windows 20= 15") which is asking the OS if it is "Windows 10", or IOW if it can handle modern ACPI features, which Linux can. So assuming that this is the cause of 0xA3 is not being set to 0x86 (*), th= en getting to the bottom of this is definitely interesting. *) Note I'm not even sure that the OSTY reference to address 0xFE0B04A3 is = the A3 we are looking for ... --=20 You may reply to this email to add a comment.
