| Note: OSPM may not have called the _DSS routines with the same values and the _DGS routines returned, because the user may be overriding the default behavior of the hardware-switching driver or operating system-provided UI. The data returned by the _DGS method (the want_XXX values) are only a hint to the OS as to what should happen with the output devices.
If the display-switching variable is set to 1, then the BIOS would not send the event, but instead would automatically reprogram the devices to switch outputs. Any legacy display notification mechanism could also be performed at this time. Index AC adapter device ID 181 power source objects 398 AccessAs term 467 acoustics 62 ACPI
