Ok. A Couple things.
First I understand the logic behind a PC going into standby mode.
Second (and it seems like I have failed to clarify) my original post was geared towards the waste of energy in all electronic devices using standby mode i.e. DVD, CD players, etc.
Is there really a need for devices other than computers to have such a feature? Does there need to be power flowing to a stereo that is not in use for example?
