3. Keyboard/mouse power (3-pin PS2_USBPW56) 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. 4. USB device wake-up (3-pin USBPW1-4, USBPW7-10, USBPW1112) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). The USBPW1-4 jumpers are for the rear USB ports. The USBPW7-10 and USBPW1112 jumpers are for the internal USB connectors that you connect to additional USB ports. Chapter 1: Product introduction 1-19
