3. 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 2.5.5 APM
Configuration).
