2. Keyboard/mouse power (3-pin PS2_USBPW1-4)
This jumper allows you to enable or disable the keyboard/mouse and USB port 5-6
wake-up feature. When you set this jumper to pins 2-3 (+5VSB), you can wake up the
computer by pressing a key on the keyboard (the default is the Space Bar), clicking
the mouse, or using a USB device. This feature requires an ATX power supply that can
supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS. The
USBPW56 jumper is for the rear USB ports.
