when you turn on the system power, and blinks when the system is in sleep
mode.

This 4-pin connector connects to the case-mounted speaker and allows you to
hear system beeps and warnings.

This 2-pin connector allows you to manually place the system into a suspend
mode, or “green” mode, where system activity is instantly decreased to save
power and to expand the life of certain system components. Attach the
case-mounted suspend switch to this 2-pin connector.
