2.. USB.device.wake-up.(3-pin.USBPW12,.USBPW34)
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 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.
3.. Keyboard.power.(3-pin.KBPWR1)
This jumper allows you to enable or disable the keyboard wake-up feature.
Set this jumper to pins 2-3 (+5VSB) to wake up the computer when you press
a key on the keyboard (the default is the Space Bar). This feature requires
an ATX power supply that can supply at least 1A on the +5VSB lead, and a
corresponding setting in the BIOS.
