2.3.10 Panel Connector
The Panel (multifunction) connector is a 20-
pin connector marked as PANEL on the
board. Attach the power LED, keylock,
speaker, reset switch, suspend switch, and
green mode LED connectors to the
corresponding pins as shown in the figure.
Some housings have a five-pin connector
for the keylock and power LED Since power
LED and keylock are aligned together, you
can still use this kind of connector.
