Peter <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #4 from Peter <[email protected]> --- Created attachment 106964 --> https://bugzilla.kernel.org/attachment.cgi?id=106964&action=edit Missing SgTbl ASL (OEMID=SgRef) For some reason, Windows knows about two additional tables, SgTbl (Switchable Graphics? OEMID=SgRef) and IffsAsl (OEMID=LENOVO). How is this possible? Some properties of this machine that may be relevant: - EFI BIOS. - NVIDIA Optimus laptop. - BIOS has option for: Intel Only / Optimus. - Without this SgTbl table, there is an error while executing \_SB.PCI0.PEG0.PEGP._DSM {...} because the external _STA, _PS0 and _PS3 methods cannot be found. This is not the first ACPI problem with Lenovo, I wonder why they hide ACPI tables...? -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
