Hi; Removing the power cord interrupts the "trickle" charge. Now no fresh charge is being added to any circuits. Pressing the cuda switch shorts any remaining charge, in cuda controled circuits, to chassis ground. It discharges any real componant capacitors and stray circuit capacitance. The "residual charge" does not have to be, actually it cannot be, discharged to "Earth Ground" by the "green" ground wire. The ground strap prevents any static charge to build up on your body, referenced to chassis ground, ie circuit ground. That static charge would destroy chips if it was accidentally discarged through the chips. Some capacitors have "Dielectric memory" , thus a long Cuda depress to help total discharge. At least thats the way I see it, Hope this helps, Ernie -- SuperMacs is sponsored by <http://lowendmac.com/> and...
