Hard Driver LED connector
This connector connects to the case-mounted HD LED cable, and the LED will light when the
hard drive(s) is/are being accessed.
This connector connects to the case-mounted reset switch which allows you to reboot without
having to power-off the system and thus prolonging the life of the power supply or system.
Depending on the setting in the BIOS setup, this switch serves two functions which will allow
you to power-on/off the system or to enter the suspend mode.
When the system's power is on, this LED will light. When the system is in the S1 (POS - Power
on Suspend) or S3 (STR - Suspend to RAM, optional) state, it will blink every second.
