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 will not power up.
• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.

This jumper allows you to enable or disable the keyboard wake-up
feature. Default setting is 2-3. Set this jumper to pins 1-2 (+5V) if
you do not want to wake up the computer when you press a key on
the keyboard. This feature requires an ATX power supply that can
supply at least 1A on the +5VSB lead, and a corresponding setting in
the BIOS.
