3. USB device wake-up (3-pin USBPW1, USBPW2)
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).
2. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) if you wish 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 .
• 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.
