2. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard 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)s. This feature requires an ATX power
supply that can supply at least 1A on the +5VSB lead, and a corresponding setting in
the BIOS.
3. USB device wake-up (3-pin USBPW1-4, 3-pin USBPW5-8)
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).
