Wire diagram


The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.

Specifically we are talking about the Reset switch, Power On switch, HarDDrive activity LED light, and Power On LED light.
Speaker pins for an onboard speaker< (BIOS Beep Codes), may be also included in this header.

What you need is a Front Panel header pinout.

I'm looking at the motherboard now,

http://www.motherboards.org/imageview.html?i=/images/mobot/motherboards/6335.jpg

The silkscreen print next to the Front panel header, is fuzzy. Probably is on your motherboard also.

[Motherboard installed in computer case, the Front panel header is at the Bottom/Right corner. Just wanted you to know, I KNOW.

The photo has the motherboard turned 90 degrees to the Right.
PANEL is silkscreened to the Right of the Front Panel header ]

Looking at the motherboard installed in the computer case, the Front Panel header is two rows of pins.

The pins have a white rectangle silkscreened around them. To the left of these two rows of 10 pins, is another small rectangle in white.
These are for IrDA,
(6 pins. Two rows of 3 pins)

http://www.webopedia.com/TERM/I/IrDA.html

Suggest leave them alone.

There are 20 pins. Two rows of 10 pins for the Front panel header.
Willing to bet Pin 1 is the pin to the upper Left corner.
Pin 20 is the pin at the bottom Right corner.

Coming from the Left side, across the Top row;
Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.

Coming from the Left side, across the Bottom row;
Pins 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20.

It looks as though this is just the old Front Panel header setup, used for a lot of old motherboards.

For example, I can just about make out the pins for the HDD activity LED light.
Bottom row, come from the Left side.

The first three pins, which are pins 2, 4, and 6, are for the Keylock.
DO not connect any wires to them!
The next two pins, 8 and 10 are for the HarDDRive activity LED.

Top row; Pins 5 and 7 look like they are for the Power On LED.

HOWEVER, let's use deductive reasoning based on intelligent thought.
Or in otherwords, 'Wing it'.

All you have to do, is get one of those LED lights that have two wires.
This will be your test unit.

Go across the Top row. Touch TWO pins at a time. For example Pins 1 and 3. No power? Touch pins 5 and 7. No power?
(Shouldn't be)

Touch pins 9 and 11, and so on. Keep going across the Top row.
No good? Go across the bottom row, BUT SKIP pins 2 and 4.

What will happen? When you finally touch, the two pins for the Power On switch, the LED light will light up, and the Power Supply will turn on.

With the Power Supply on you can go back, and see which two pins keep the test LED light ON. These pins will be for the Power On LED.

Test LED light blinks? You are touching the pins for the HarDDrive activity LED.

Windows is running, and you touch two pins, and Windows restarts?
You have the pins for the Reset switch.

Speaker pins will be FOUR pins in a row, and by finding the rest of the pins, you will know which ones these are.

BY using the LED light you will harm NOTHING. In fact you could use a jumper wire. If you touch the wrong pins, NOTHING will happen. If you touch the two pins for the Power On switch, the Power Supply will come on.

Shock Hazard:
The VOLTAGE is 5 Volt DC.
In comparison two D cell flashlight batteries store 3 Volts DC.

In otherwords; NONE.

For additional questions please post in a Comment.
It may be hard for you to navigate around this website, but would appreciate hearing back from you.

Perhaps you can post a Front Panel header pinout, for this motherboard, and be somebodies hero.

Just a thought.

Regards,

Connecting hdd led lead and power led lead,where do they go ?


Hi, There are 3 versions of this motherboard; 1.0, 2.0 & 3.3, but the layout is identical. The general layout is shown in pins.jpg. For the power led, the white wire goes to the (-) terminal either pin 2 or 3, both are MPD- while the green goes to the ( ) or pin 1 (MPD ) as shown in powerled.jpg HDDpins.jpg shows the connection of HDD led, the white goes to pin 3 or HD- while the red goes to pin 1 or the HDD . I cropped these images from the manual which is also available at the gigabyte website. Hope this gives you some ideas and workout of you. Good luck and pls post again how things turn up. Kind regards.
