A number of signals for system control and for SMBus communication are provided through a 2x12-pin
connector. This connector combines signals for power button, speaker, and several LEDs such as a
suspend LED, and three additional LEDs which are driven by GPIOs. Of these three GPIO-LEDs, LED1
and LED2 are already provided with a series resistor. SMBus capable devices can also be connected.
