Hi, I'm having ABIT Quad GT MB and I was wondering what are usb pwr jumpers used for. I set them to enable, and I still can not start up my PC with a Keyboard key Power, allthought it works when I need to shut it down. I can clearly see, that USB has power and if I press power button on my keyboard, receiver flashes. Is it posible to start a PC via USB wireless keyboard? Thanks!
