Thanks for the reply.

I changed out every component on the computer for ultra-quiet stuff, so the fan is silent even when you open the case and put your ear next to it, same for PSU and all other fans e.g. I run a silent Asus 9400GT card. Which makes it difficult to hear anything The machine is genuinely silent.

What I found was that the lights do go off on the case.

I haven't changed the fakesmc kext over, but wonder if PleaseSleep has the same functionality?

Do you have to press the power button to resume from sleep or can you do this from the mouse or keyboard? I have to use the power button.

Rob.
