   I already own one of those fiber-hdmi cables. Brilliant, but sometimes doesn't interoperate with DVI devices using passive DVI -> HDMI adapters. I've no idea if it has any copper conductors for HDMI power, though one end is lab

   > scratch that we needed smaller ;-) Well... Needed smaller in terms of resistance, but needed bigger in terms of power rating, in the interests of not catching fire.

   12 ohms brings the rail down to 1.47 volts, still no SSD. 6 ohms is enough to finally break/trip whatever circuit is allowing this situation, bringing the rail down to 0v in power-off. Of course, that's almost 2 watts of constant

   Hi! I'm the OP from the Level1Techs thread. That HDMI power has some grunt behind it. During power-off state with that 1.90v phantom voltage, I put a 48ohm resistor between 3V3 and ground, the phantom voltage only dropped to 1.80v, and
