4. 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) 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 2.5.1 Power Up Control).
