Need pinout for A8N-LA front panel to mobo


Mike,

Going to detail it out, so those needing this info in the future also, can use it.

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c00647121&dlc=en

Scroll towards the bottom of the page for the motherboard illustration, and photo.

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

In the illustration, and as the motherboard sits in your computer case, the Front Panel is at the Bottom/Right corner.
In the Illustration it is F_PANEL1.

In the photo it is the black rectangular block, with 9 contact pins.
Two rows of pins.
4 on the Top row, 5 on the Bottom row.

The pins on the Top row are numbered EVEN.
The pins on the Bottom row are numbered ODD.

Starting on the LEFT side on the Top row, going across to the Right;
Pins 2, 4, 6, and 8.

Starting on the LEFT side on the Bottom row, going across to the Right:
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED.
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a RST SW is used.

C) Pin 9 is N/C.
Not Connected. Pin is reserved for factory use.

D) Pins 2 and 4 are for the Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

F) There is NO Pin 10. Just a blank spot.

Power front panel conectors on acer 915m08


This Foxconn 915M08-G-8KS motherboard made for Acer Veriton desktop computers?

http://www.sella.co.nz/general/computers/components/motherboards/other-motherboards/b1jnj6/

Do not know what the Front Panel header pinout is.

(Front plastic part of computer tower is the Front Panel.
Area of contact pins on the motherboard, that the wires (Cables) from the Front Panel connect to, is the Front Panel header )

CAN see by clicking on - View full size image - that the Front Panel header is to the Top Left corner of the motherboard, by the CMOS battery.
(View of mobo is upside down, in relation to how it actually sits in the computer tower case)

Shows me it is just the normal two rows of contact pins used in a LOT of desktop computer mobo's. (MOtherBOard)

If it were I, I would use one of the LED lights connected to two wires, and touch across each two sets of pins.

Looking at the motherboard as it sits in the computer case, there is a row of pins on Top, and a row of pins on Bottom.

In your mind start at the LEFT side of the pins at the TOP.
Number them from Left to Right.
Example, Pins 1, 3, 5, 7, and 9.

Now number the pins on the Bottom, from Left to Right,
Pins 2, 4, 6, 8, and 10.

Computer plugged into power, touch the two wires of the LED light, to Pins 1 and 2.
Computer doesn't start? (Power Supply turns on)
Go to the next set of pins.

I am willing to bet Pins 5 and 6 turn the Power Supply on.
No? Keep experimenting.

What will happen if you touch the WRONG pins?
N-O-T-H-I-N-G
You will NOT hurt the motherboard.

When you get to the correct pins, the Power Supply will turn on.
These pins are for the Power On switch.

Now go back through the pins with the Power Supply on, but DO NOT touch the pins that turned the Power Supply on.

When the LED light STAYS on, you have the pins for the Power On LED light.

If the LED light BLINKS, you have the HarDDrive activity LED light.

If Windows starts to load, and you touch the Restart switch pins, the computer will restart over again, and Windows will load again.

(IF this computer has a Restart switch. I do NOT use one, even for the older computers. Just press CTRL, ALT, and DELete keys at the SAME TIME, to restart the computer, or use the Task Manager option)

One pin left all by itself? That is for 5 Volts, and only used by the factory. Leave it unconnected.

There may also be a blank spot on the Front Panel header, where it looks like a pin is missing. This is the KEY pin, and is not used.
It is just to orient where the other pins are.

Worried about getting shocked?
There may be a small spark, as you connect the wires, I will gramnt you that.
But the voltage is 5 VOLTS DC.
In comparison two D cell flashlight batteries produce 3 VOLTS DC.

The harmful AC voltage is contained in the metal enclosure, of the Power Supply. Can't get you unless you pour water on it close up, or stick a metal rod through one of the ventilation holes, in the Power Supply enclosure.

Regards,
joecoolvette

By the by. You could be a lot of people's hero, if you came back, and posted the pins for what they do. Post in a Comment.

If my information is correct;

Orient the motherboard so that we are both looking at it in the same direction,
Processor to the top, Ram Memory slots to the right, white PCI slots to the bottom.

The front plastic panel of your computer that has the Power On button, Harddrive activity LED light, and Power On LED light, is the Front Panel.

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

The Front Panel header is all the way down on the right corner. Panel 1.

The Front Panel header, or Panel 1, is a rectangular block that is positioned lengthwise, across the bottom of the motherboard.

There are 4 pins across the Top, and 5 pins across the Bottom.

I have a GA-81865GME-775-RH motherboard, which i put into my box, made all the connections, but have no power once I switch the box on. I suspect it has something to do with the wiring loom running from...


Hello julian_ad681

I will tell you how wire your case front panel, but before that lets test the motherboard to make sure the problem is not the board itself.

Remove all the wire connections to the front panel.

Turn the power on and with a small screw driver or anything that is metal short (touch) the two pins that are the PWR SW. (look at the list of pins I have put at the end)

If the computer turns on then it means the board is ok.

The following information is also availabe in the motherboard manual available from the gogabyte web site download section

On the motherboard next to the battery is the front panel header pins. it looks like

0 0 0 0 0 0 0 0 i also write them as numbers as well to make it easy for you)
0 0 0 0 0

1 2 3 4 0 0 0 0
5 6 7 8

1 and 2 are message LED. you don't need any connection to this.
3 and 4 are the power switch connections no polarity, just connect the wires
5 and 6 are the hard disk LED. 5 is the positive side (usually red)
7 and 8 are the reset switch. no polarity, just connect the wires.
Next to the message LED there is a three pin connection. This is for the power LED.


hope this has helped you.

My power led connector (green,white) power sw connector (black,white) got out of place and i dont where they go


The eMachines T3302 desktop computer, uses an FIC K8M-800M motherboard.
(First international Computer, Inc.)

Where those wires go on the motherboard, is termed a Front panel header.

The Front Panel is the plastic front bezel of your computer.
(Where the Power On button is, Power On LED light, and so on)

Looking at the motherboard with the Processor to the Top, Ram Memory slots to the Right, the Front Panel header is at the bottom right corner, and over to the left.

Look at the jumper block in the bottom right corner. Right in the corner.
This is the LED type selector, jumper block.
Has 6 pins.
3 across the Top, 3 across the Bottom.

(This jumper block is to set whether you are using a Power On LED light, that has Dual Colors, or a Single color.
The default setting of the jumper on the block, is set to use a Dual Color LED light, for the Power On LED)

Move to the left of this jumper block. The Front Panel header is to the left of this jumper block.

(FIC terms it a Front Panel Block Connector)

It should be White in color.
Is right against the bottom edge of the motherboard. (Parallel to the outside edge of the motherboard)

Has two rows of pins sticking up.
5 across the Top.
4 across the Bottom.

The pins are numbered from the Right, going towards the Left.

(From the Power On LED jumper block, towards the Front Panel header)

On the Top row going from Right, towards the Left,
Pins 1 ,3, 5, 7, and 9.

On the Bottom row going from the Right, towards the Left,
Pins 2, 4, 6, and 8.

A) Pins 1 and 3 are for the Power On LED light.
Pin 1 is for the Positive ( + ) wire.
(Green)

B) Pins 5 and 7 are for the Power On switch.
Pin 5 is for the Positive ( + ) wire.
(Black)

[Although it really doesn't matter which way the wires go. It's a SWITCH]

C) Pins 2 and 4 are for the HarDDrive activity LED.
Pin 2 is for the Positive wire ( + )

D) Pins 6 and 8 are for the Reset switch.
(IF used)

If any of your LED lights are dim, after attaching the Positive wire for each LED, it's because the Positive wire is on the wrong pin.
Switch the wires around

I have an 945gzt-m v 1.0 and dont know were the pwr sw wire goes


Yes.
First, let's orient the view of the motherboard, so we are both looking at it the same way.
The processor is at the top middle, and the Front panel header, is to the very bottom right hand corner.
Right next to the motherboard mounting hole.
The Front Panel header goes across the bottom edge of the motherboard, lengthwise.

Looking at the top row of pins on the Front Panel header, No.2 Pin is at the far left. Pins 2, 4, 6, 8 and 10, go across the top.

Looking at the bottom row, No. 1 Pin is at the far left. Pins 1, 3, 5, 7, and 9, go across the bottom.

The power switch wires go to Pins 6 and 8.
The HDD LED wires go to Pins 1 and 3.
The power LED wires go to Pins 2 and 4.

On the power switch wires, the Positive (+) wire goes to Pin 6. Just in case this wire is marked.
(Doesn't really matter which way it goes, because it's a switch!)

On the HDD LED wires, the Positive (+) wires goes to Pin 1.

On the power LED wires, the Positive (+) wire goes to Pin 6.
