HD_LED (Hard Drive LED )
If your case front panel has a hard drive LED cable, attach it to this header. The LED will
flicker when there is hard disk drive activity.
ACPI_LED (2 pin Power LED)
This header can be attached to the power LED cord from the case front panel onto this
header, then the power LED will illuminate while the system is powered on.
RST_SW (Reset Switch)
This header can be attached to a momentary SPST switch (reset button) cable on your case
front panel. The switch is normally left open. When the switch closed, it will cause the
mainboard to reset and run the POST (Power-On Self Test).
PWR_SW (Power-on Switch)
This header can be attached to a power switch cable on your case front panel. You can turn
your system on or off by pressing the button attached to this power switch cable.

1.4.2 JP1: Clear CMOS Jumper
The "Clear CMOS" function is used when you are unable boot your system and need to reset the
BIOS settings (CMOS settings) back to the manufacturer's original settings. This is also a way to
reset the system password if you have forgotten it.
JP3 Assignment
Note: "Closed" means putting a jumper cap onto two adjacent header pins.
1. Turn off your system and disconnect the AC power cable.
2. Set JP3 header to OFF (2-3 Closed).
3. Wait several seconds.
4. Set JP3 header to ON (1-2 closed).
