I broke the power switch when opening the case up for an IVAD cable replacement. I think I've located a substitute. Does anyone have a schematic or know how the switch operates? There are three lead/terminals on the switch. I'm hoping one side is normally open and the other is normally closed (that's the substitute) but I can't test the busted switch. Thanks P.S. The nearest Apple store is 2500 nmi. I'm located at 167 deg long, 9 deg lat in the Republic of the Marshall Islands in the Central Pacific.
