Now that more parts have arrived from eBay again I'm back on track with my Sega Genesis Mark II build. This has lead to me come up with two questions that I was hoping some people may have answers to or point me in the right direction.
Where or how to enable always on USB Port?
I know at some point motherboard companies started to introduce charging ports on motherboards several years ago, but since then it seems to have dropped off entirely. I know some motherboards have EUP, I'm just not sure exactly how to enable this specifically for ASUS or if it's usually a specific internal or external usb port.
Can I use the AI Charger suite Asus has to do this too? I need a 5V constant voltage source (even when the pc is off but plugged into a power outlet) and I'd like to avoid having a second power adapter coming out of the case.
Power specs for the motherboard LED/Power Button?
For the power LED I've measured it to be 5.1V I just was wondering if anyone knew what sort of current draw it'll supply. I will most likely use a voltage divider circuit to drop the voltage down below 5V, in which that'll properly protect my digital input port.
This goes also in part with the power button supply to. If anyone knows typically want current draw it can supply, I could use that as my arduino power source as I plan to relay the on/off power connection duty to the arduino through some circuitry.
