RE: Question for UPAMD control


Paul,

Does this application level of functionality already exist outside UPAMD over LAN, USB, or video?  If not, I see a marketing value to powering down the entire desk when the CPU is powered down.

I agree we shouldn't use a hard shutdown of smart peripherals, but powering down stupid peripheral (a desk lamp for example) shouldn't need the additional cost of circuitry to collaborate.

Thanks,

Hello Stephen:
 
In my view, this is application level functionality outside the scope of the UPAMD spec.  What is important is that UPAMD provides primitives so that any vendor wishing to implement this clever on/off energy-saving feature can do so.
 
That said, we may want to consider a message type RequestShutDown.  While we can clearly implement a scheme where the power hub shuts down power to peripheral devices when the PC shuts down without the need for exchanging messages, it would be nice to be more collaborative to give the peripherals a more graceful shutdown option or to refuse shutdown if needed.
 
Best regards,

Subject: Question for UPAMD control
 

All,

Is there any way to control power to multiple devices based on the activity of one device one device?  

A handshake with the computer that indicates it is going to sleep, or being shut off (even though a battery may be charging in a laptop) would turn off the unneeded peripherals.  A peripheral manufacturer may design this in, or a user can choose from the list of attached devices.  The latter would be needed for a peripheral like a WiFi enable printer can be selected for shutdown if unused by others, or left on.

The same this would apply if UPAMD is used for a home entertainment system (TV off, DVD player, surround sound, etc. off, DVR remains on).

Taken to the extreme, an office or a home could use UPAMD to control all its power (with UPAMD adapter modules to control things requiring 240W and above).

A computer tied system has the advantage of being able to use software control, other applications may not afford a sophisticated control system.

Thanks,
