Hi

On my motherboard GA-B85M-D3H, there are two power led headers: PLED (2-pin) and PWR_LED (3-pin). If I use one set, would the other set still be powered? I'm thinking to add a led so that it switches on when the machine is in standby (on this board the power LED switches off even in standby), so I wonder if I could use both PLED and PWR_LED. My plan is to use Arduino to detect an OFF in PWR_LED and switch on the led. Unfortunately it won't be able to distinguish between standby and power-off.

Thanks
