Hi,
Away Mode does the following when invoked:
· Shuts down the video signal at the port
· Mutes all system audio
· Blocks HID and PS/2 input devices (so your cat does not walk across the “delete” key and delete your library)
· Puts the CPU into “adaptive” mode, which may save power depending on what’s running
· Notifies kernel-mode and user-mode components of the transition (enables HW like video cards to clock-down or front-panel displays to change content, enables SW to do “smart” things like IM going to “away”)
· Notifies the BIOS through an ACPI control method of the transition (enables the power LED to change from green to whatever, enables a different thermal profile to be put in place if the OEM decides)
· Wakes back up when flash devices (USB FOB, flash card) are inserted
· Wakes back up when an optical disc is inserted in the drive
The intention here is to provide a “user not present” state to the machine so you can walk away, know that your recording is going to happen (or not be interrupted) while not badgering the user with a screen, audio, etc. It is *not* intended to be a power management state. Today, this is the only way to ensure that your media center extender will always work w/o having to worry if your MCE host is turned on or not. Also is great in that the system does not have to wake from S3 to record – and become noisy in the process.
