Pin Configuration = Pinout

The Front plastic panel of the computer is the Front Panel.
The area of pins on the motherboard that the cables (Wires) go to, is the Front Panel header.
Front Panel header pinout.

The motherboard used in an eMachines T2672 desktop computer is an FIC AU31 motherboard.
Made by First International Computers (Inc.) for eMachines.

http://www.e4allupgraders.info/dir1/motherboards/socketa/au31.shtml

Orient the motherboard like it is in the photo, so 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 way it sits in the computer case}

The Front Panel header, is a small black rectangular block that sits horizontally, at the far right bottom corner.

It has two rows of pins.
4 across the top, and 5 across the bottom.

(The small rectangular block above it, is for connecting a Power On LED light that has 3 wires. More on this in a moment)

The pins are numbered.
The pins are numbered Evenly across the top, and Odd across the bottom.

Starting from the Left side going across to the Right, on the Top row;
Pins 2, 4, 6, and 8.
There is No Pin 10.

Starting from the Left side going across to the Right, on the Bottom row;
Pins 1, 3, 5, 7, and 9.

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

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

C) Pin 9 is Not Used. (NC. No Connection)

D) Pins 2 and 4 are for the Power On LED light, IF it is a 2 wire LED light.
Pin 2 is for the Positive ( + ) wire.
(If the LED light is dim, switch the wires around)

If the Power On LED light has 3 wires:
Use the Power On header above the Front Panel header.
This rectangular block has 3 pins.

Starting from the Left side going to the Right; Pins 1 , 2, and 3.
Pin 1 is for the Positive wire.
Pins 2 and 3 are Ground wires.

E) Pins 6 and 8 are for the Power On switch. (Power On button plastic assembly has an ATX power on switch inside it)

This is a link to a free motherboard manual, for the FIC AU31 motherboard. It is in Zipped file form.
(A Zipped file is a compressed file. It is used for one, to send a large file over the internet)

If you do not know how to unzip a file, post in a Comment, and I'll lead you step by step.

http://www.elhvb.com/mboards/OEM/eMachines/manuals/index.html

In the list on the left side, left-click right on the file name - AU31

[ P.S.
The motherboard chipset is an Nvidia Crush 18G + MCP AGP
It is an Nvidia Force 2 chipset,

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_chipsets#nForce2

Supports Processors that are AMD, and fit in a Socket A processor socket.
(Socket A is also known as Socket 462)

Supports AMD processors that have either a 200MegaHertz Front Side Bus, or a 266MHz FSB, or a 333MHz FSB.

AMD Athlon XP processors with either a 266MHz FSB, or 333MHz FSB.
From the 1500+ model up to the 2800+ model.

AMD Duron processors with a 200MHz FSB.
From the 800MHz to the 1.3GHz models

(AMD Athlon XP is the top of the line. Then it's Duron, then Sempron.
A Sempron processor has half of the L2 cache that a comparable Athlon XP does)

Ram Memory is DDR Sdram at either 200MHz, or 266MHz, or 333MHz, or 400MHz.
Depends on the Processor used.

(Ram Memory typically operates at half of the frequency rate ('Speed') that the Processor does.
If the processor's FSB is 333MHz, you can use 400MHz DDR Sdram. {PC3200}

Confusing I know.
DDR Sdram is 'double-pumped'. It is actually 200MHz for PC3200.
This is close to half of 333MHz.

Processor has an FSB of 266MHz? Ram memory used will be 266MHz. Remember, it is actually 133MHz for the ram memory. (PC2100)

Need an AMD Athlon processor?
I found this place years ago. Not advertising for them. Just computer geeks sticking together, and sharing information. (I have bought a motherboard from them, and it works fine),

    I wish I had seen this thread before I had searched all over the net with no results. This is EXACTLY the order that worked for me, although I have an T3065 with the AU31 mb (a.k.a. K7m-NF18G mb)

I need the wiring diagram for emachine model D6405

Usually it is in very small print right on the motherboard next to the pins, use a flashlight and/or a magnifier to see what order the pins go in. The hard drive light will say HDD, power will say PWR, etc.

Need to re-attach power button cable, hard drive

The manual for your computer is available from emachines, p.168 shows the info you need (replacing the front I/O panel)
http://downloads.emachines.com/userguides/8511279_eM_NG3_chassis_HW_ref_en.pdf

The good news is that you can't harm the computer by connecting the wires wrong and the bad news is they just won't work the way they are supposed too if not connected properly. The LED's must have the correct polarity to work.
In general, if you look real close (as in magnifying glass and flash light) you will see the ID for each set of pins is printed on the motherboard (pwr,rst,HDD,pwr sw,speaker) Just match what it says on the motherboard to what it says on the wires. Don't worry if you get the polarity wrong. If a light doesn't work just swap the two wires. The colored wires should be positve (+), though. The reset (rst) and power switch (pwr sw) wires don't require polarity.
These instructions are for most computers in general, YMMV.

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.

Emachines t3830 I need the schematic for MB I umployed the wire for the push bottom without looking at the way they were plug. Now I do not know the correct aligning of the push bottom wires.

If you look at the motherboard there is usually a diagram labeled "FRONT PANEL HDR" that will tell you which pins are for: HDD LED, PWR LED, RESET, PWR ON. etc.
The chart / diagram may be a few inches away from front panel header.
the following example is from my emachine T2893 that I had opened because it won't power up.

the motherboard at the header connector labels pin #2 and with that you can figure out the other
pin numbers

example of diagram on motherboard (Confirm the pin numbers on your motherboard)


J9G1 PINS
| HD LED | 1 - 3 |
| PWR LED | 2 - 4 |
| RESET | 5 - 7 |

| PWR ON | 6 - 8 |

Hope this helps you figure which pins to hook you switch up to.

Connecting the case to my motherboard

Pin arrangment is Industry Standard Architecture.....

pwr led pwr sw N/C
X X X X O

X X X X O

hdd rst N/C

translated this is top row left to right ...... power led, power switch no connection

Bottom row is left to right........ hard drive, reset, no connection

Note: not all computer cases have a reset button, also the connectors for power led and hard drive produce a light, if the light does not show, power off the pc swithc the cable rooun 180deg on the connector pins and reconnect.

Motherboard pin config

All motherboards have a print beside the pins, Speaker= "speak", "pwr s" =powerswitch, "HDDled" red light on front, rst = reset switch [not allways used] "pwr led" Green led, the case wires are usualy marked on the plug ends with the same , "hdd" "reset" and so on. The power switch will work both way's around however the led lights wont. You will not hurt anything if they are the wrong way around, they just wont work so if you dont get lights just reverse the polarity. If by chance the case wires do not have labels the just trace them to the case front panel and plug them into the corresponding board pins. Regards mistyman
