Direction of the Arrow Sign on the Male Push Pin

The Top of Female Push Pin

Female Push Pin

Step 1: Apply an even and thin layer of thermal grease on the surface of the installed CPU.

Step 3: Place the cooler atop the CPU, aligning the four

push pins through the pin holes on the motherboard. Push down on the push pins diagonally.

Step 2: Before installing the cooler, note the direction of

the arrow sign on the male push pin. (Turning the push pin along the direction of arrow is to remove the cooler, on the contrary, is to install.)

Step 4: You should hear a "click" when pushing down

each push pin. Check that the Male and Female push pins are joined closely. (Refer to your CPU cooler installation manual for instructions on installing the cooler.)

Step 5: After the installation, check the back of the moth-

erboard. If the push pin is inserted as the picture above shows, the installation is complete.

Step 6: Finally, attach the power connector of the CPU

cooler to the CPU fan header (CPU_FAN) on the motherboard.

The battery provides power to keep the values (such as BIOS congurations, date, and time information)

in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low level, or the CMOS values may not be accurate or may be lost.

You may clear the CMOS values by removing the battery:

1. Turn off your computer and unplug the power cord.

2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder, making them short for 5 seconds.)

3. Replace the battery.

4. Plug in the power cord and restart your computer.

• Always turn off your computer and unplug the power cord before replacing the battery.

• Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with

an incorrect model.

• Contact the place of purchase or local dealer if you are not able to replace the battery by yourself or uncertain about the battery model.

• When installing the battery, note the orientation of the positive side (+) and the negative side (-) of the battery (the positive side should face up).

• Used batteries must be handled in accordance with local environmental regulations.

• MSG/PWR (Message/Power/Sleep LED, Yellow/Purple):

System Status LED

S0 On

S1 Blinking

S3/S4/S5 Off

Connects to the power status indicator on the chassis front panel. The LED

is on when the system is operating. The LED keeps blinking when the system is in S1 sleep state. The LED is off when the system is in S3/S4 sleep state or powered off (S5).

• PW (Power Switch, Red):

Connects to the power switch on the chassis front panel. You may congure the way to turn off your

system using the power switch (refer to Chapter 2, "BIOS Setup," "Power Management Setup," for more information).

• SPEAK (Speaker, Orange): Connects to the speaker on the chassis front panel. The system reports system startup status by is-

suing a beep code. One single short beep will be heard if no problem is detected at system startup. If a problem is detected, the BIOS may issue beeps in different patterns to indicate the problem. Refer to Chapter 5, "Troubleshooting," for information about beep codes.

• HD (Hard Drive Activity LED, Blue) Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive

is reading or writing data.

• RES (Reset Switch, Green): Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer

if the computer freezes and fails to perform a normal restart.

• CI (Chassis Intrusion Header, Gray): Connects to the chassis intrusion switch/sensor on the chassis that can detect if the chassis cover

has been removed. This function requires a chassis with a chassis intrusion switch/sensor.

The front panel design may differ by chassis. A front panel module mainly consists of power switch, reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your chassis front panel module to this header, make sure the wire assignments and the pin assignments are matched correctly.

8) F_AUDIO (Front Panel Audio Header)

G.QBOFM

The front panel audio header supports Intel High Denition audio (HD) and AC'97 audio. You may connect

your chassis front panel audio module to this header. Make sure the wire assignments of the module connector match the pin assignments of the motherboard header. Incorrect connection between the module connector and the motherboard header will make the device unable to work or even damage it.

• The front panel audio header supports HD audio by default. If your chassis provides an AC'97 front panel audio module, refer to the instructions on how to activate AC'97 functionality via

the audio software in Chapter 5, "Conguring 2/4/5.1/7.1-Channel Audio."

• Audio signals will be present on both of the front and back panel audio connections simultaneously. If you want to mute the back panel audio (only supported when using an HD front panel

audio module), refer to Chapter 5, "Conguring 2/4/5.1/7.1-Channel Audio."

• Some chassis provide a front panel audio module that has separated connectors on each wire instead of a single plug. For information about connecting the front panel audio module that has different wire assignments, please contact the chassis manufacturer.

9) F_USB1/F_USB2 (USB Headers)

The headers conform to USB 2.0/1.1 specication. Each USB header can provide two USB ports via an

optional USB bracket. For purchasing the optional USB bracket, please contact the local dealer.
