This is an odd request, but i built myself a Windows based steam machine. My intention was to leave Steam's big picture mode on at all times and set the power button to 'sleep.' The problem is that when the PC is in sleep mode, the power light on the Cooler master elite 130 blinks. Maybe it's just me, but this is annoying the hell out of me especially as it illuminates my room at night. Any way to stop the light from doing this, short of pulling the led cable from the motherboard?
