6. Keyboard Wake Up (3 pin KBPWR1)

This allows you to disable or enable the keyboard power up function. Set this jumper to Enable if you wish to use your keyboard (by pressing <Spacebar>) to power up your computer. This feature requires an ATX power supply that can supply at least 300mA on the +5VSB lead. The default is set to Enable. (The computer will not power ON if you set this to Enable but do not have the correct ATX power supply. NOTE: This jumper must be set in conjunction with Wake On PS2 KB/PS2 Mouse/CIR in 4.5.1 Power Up Control.
