1-7 Chapter 1: Product introduction
3. USB device wake-up (3-pin USBPW56)
Set this jumper 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 USB device wake-up feature requires a power supply that can provide 500mA on
the +5VSB lead for each USB port; otherwise, the system would not power up.
• The total current consumed must NOT exceed the power supply capability (+5VSB)
whether under normal condition or in sleep mode.
2. Keyboard/mouse power and USB device wake-up (3-pin PS2_USBPW1-4)
This jumper allows you to enable or disable the keyboard/mouse and USB port 1-4
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, 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 USBPW1-4 jumper is for
the rear USB ports.
The total current consumed must NOT exceed the power supply capability (+5VSB)
whether under normal condition or in sleep mode.
