feature. Set this jumper to pins 1-2 if you wish to wake up the computer

The keyboard wake-up feature requires a power supply that can

provide at least 1A on the +5VSB lead. If this requirement is not met,

the system does not power up. The total current consumed must NOT

exceed the power supply capability (+5VSB) whether under normal

condition or in sleep mode.

This jumper allows you to enable or disable the audio CODEC on the
