Randy,

I suppose you need to clarify your technical requirements. Many
motherboards offer soft power control for "wake up" events. It is a part
of the ATX power specifications, often referenced as "PS_ON#" as in
"PS_ON Signal voltage".

In operational sense, your machine is off. There is still a 0.8v
power being generated from the ATX power supply to enable switching
(i.e., to turn to the machine 'on'). This is using the buttons on your
computer for power. Yes, you can suspend but that is a different
function altogether. Not the same as the soft power control. The idea is
that ATX power supplies are never truly off, just as when your
television is plugged in, it isn't off either and starts up via soft
boot (e.g. the remote power button).

Finally, as we are speaking to the future, we need references to
this in power specifications. We need someone from Intel (who authored
the specification I believe) or similar such as the Energy Star, Germany
Blue Angel RAL UZ 78 certification, or perhaps someone at the Department
of Energy who can give us existing specifications or vendors with exact
implementations.

This isn't new. It's old. The BIOS must support it however. I
hope that is useful to you.

Norman:

The power-on requirement is not just an example. It's a real
requirement
that we are looking at on the hardware SC. More to David's question -
we
know you can wake a computer from a sleep or hibernate mode using the
keyboard. But that's different than turning it on from a cold
shut-down,
which is the issue being addressed.
