[Boatanchors] Wall Warts and Switcher Power Supplies

[Bill Cromwell]

Hi,

It's been a long while now that computers, printers, etc with an
internal, switching power supply have an arrangement where the power
switch is NOT a power switch at all. That button you press signals the
equipment's mother board that you are ready and then mother board turns
the power on or off. In order for it to do that there must already be
power to the portion of the board that handles that task. Granted that
it will be much lower power than when the whole system is on but powered
nonetheless. I have some digital stuff here that I can hear on my radios
on some bands - even when it is turned *off*. Make that pseudo-off. I
have that stuff plugged into power strips with a *real* power switch. At
my house off is *off*. Lights out. Don't just go to sleep - die.
