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 (the default value is
[Disabled]). This feature requires an ATX power supply that can supply
at least 1A on the +5VSB lead and a corresponding setting in the
BIOS. (see section 4.5.1 Power Up Control)
