the pin locations and definitions of the control panel buttons and LED indicators.

The Power Button connection is located on pins 1 and 2 of JF1. Momentarily contacting both
pins will power on/off the system. This button can also be configured to function as a suspend
button with a setting in the BIOS (see Chapter 4). To turn off the power when the system is
in suspend mode, press the button for 4 seconds or longer. Refer to the table below for pin
definitions.
