How to hook up the face plate of a emachine w3400 Wich includes 3 wires 1 power butten and 2 led lights

A service manual for any eMachine will not be available. The best you will be able to get is a "user manual" which is next to useless for actually servicing a problem. eMachines are notorious for poor and non existent documentation.

The eMachines T3306 desktop computer, uses the FIC K8M-800M motherboard.
First International Computer, (Inc)

Here's the download page for the motherboard manual,

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

Column in middle, 3rd file from bottom.

This is a Zip file. A Zip file is a Compressed file. Used to send large amount of information more easily.
Has to be decompressed, or 'unzipped'.

After you click on the blue -> FIC K8M-800M file name, a small window will come up-
Opening K8M-800M_manual.zip

Make SURE there is a Green dot in the small circle, to the left of Save File.
IF not; click in the empty circle to the left of Save File.
No go below in the small window, and click on OK.

A small download window will come up.
Allow the file to fully download all the way, then DOUBLE-click right on the file name.
(Yellow folder icon with a zipper on it. K8M-800M_manual.zip is to the right)

In the next small window go to the far Left, and click on -
Extract all files.
At the bottom of the next 3 small windows click on Next, Next, and Finish.

In the last small window DOUBLE-click right on the file name ->
K8M-800M_manual
(Next to the red Adobe PDF icon)

There is your motherboard manual in PDF file form.

For an example;
The front of your computer is the Front Panel.

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

Motherboard installed in computer case, the Front Panel header is at the Bottom/Right.
The Front Panel header is Orange in color. (Page 20)

Two rows of contact pins.
5 pins across the Top row.
4 pins across the Bottom row.

rEaLLy? Let me check my schedule................yep, I can fit you in.

The eMachines W3400 Desktop PC uses an MSI MS-7145. Also known as the MSI RS480M-IL,

http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1261749&CatId=1619

Starting with an empty eMachines W3400 computer case;

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.
Poof! You probably won't see it, or feel it.

(A Processor is the MOST susceptible hardware computer component to Static shock )

Computer ON a table, computer unplugged from power, (Bear with me), computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case. This action will relieve your body of Static.
SHOULD you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

Make sure you are relieved of Static -> BEFORE touching any parts, also. Before you take any of them out of their anti-static bags, or cartons. (In case you buy some new stuff)

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

1) Got the pinout for the Front Panel header? Know what pins those wires go to?
I don't know of a motherboard manual out there, that is readily available. This is because it is a motherboard made by MSI for eMachines. It is not an MSI O.E.M. motherboard.

Going with the Front Panel header pinout for an MSI RS480M, and let's see if it is the same;

Motherboard mounted in computer case;
Processor to the Top, Ram Memory slots to the Right, 3 white long PCI slots to the Bottom:

The Front Panel header is at the Bottom/Right corner. It is actually TWO headers.
JFP1 and JFP2.
(Junction Front Panel 1, Junction Front Panel 2)

8 pins across the Top row, NO pin.
3 pins across the Bottom row, NO pin, 5 pins.

It is labeled with colored areas around the pins.
JFP1 is so many pins, JFP2 is so many pins.

JFP1:
Starting at the RIGHT side going towards the LEFT; TOP row;
NO pin, Pins 8, 6, 4, and 2
Starting at the RIGHT side going towards the LEFT; BOTTOM row;
Pins 9, 7, 5, 3, and 1.

A) Pins 1 and 3 are for the HarDDrive activity LED light.
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 Reset switch is used.

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

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

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

The next set of pins to the LEFT of Pins 1 and 2 in the JFP1 header, are the pins for the JFP2 header.
Starting at the RIGHT side going towards the LEFT; TOP row;
Pins 8, 6, 4, and 2.
Starting at the RIGHT side going towards the LEFT; BOTTOM row;
NO pin, Pins 5, 3, and 1.

A) Pins 1, 3, and 5, are for a Power ON LED that has dual colors.
Pin 1 is for the Ground wire. ( - )
Pin 3 is for SLED. (Sleep) Pin 5 is for PLED. (Power)
B) NO pin 7
C) Pins 2 through 8 are for a small speaker. The speaker is for BIOS Beep Codes. Pin 2 is the Ground ( - ) wire. Pin 4 is N/C. Pin 6 is N/C. Pin 8 is for the Positive ( + ) wire.

Motherboard:
Install the Processor, and Ram Memory to the motherboard, before installing it in the computer case.
Why?
Because you can see if you have the Heatsink/Fan combo, mounted correctly.
Looking at a 'birds eye' view across the motherboard, see if the finned Heatsink is sitting F-L-A-T on the Processor. If not make adjustments.

The Top of the Processor, and bottom of the finned Heatsink, MUST be clean. If you are reusing, scrape the top of the Processor off, and bottom of the Heatsink, with a suitable PLASTIC scraper. I use an old credit card. (Yeah, send me sum more in the mail guy's! Lol!)

If there is a Thermal Pad, peel it off, fly it at the cat. They are J-U-N-K, and can't be reused anyway.
Then use Q-tips dipped in Isopropyl Alcohol. (Rubbing alcohol.
93 percent is best, 70 percent will do. 50 percent = No in my book. 50 percent Alcohol, AND 50 percent WATER)
May be a gooey mess, and will take a lot of alcohol dipped Q-tips.
C-L-E-A-N!! Clean enough to eat off of.

CAUTION!! Isopropyl Alcohol is EXTREMELY FLAMMABLE!
Use in a WELL ventilated area with NO sparks or flames present!

Put a small pea-sized drop of Thermal Paste, in the center of the top of the Processor. Set the Heatsink/Fan combo down on top. FLAT.

From here I am going to give you a link to MSI Support, for the motherboard manual for the MSI RS480M/RS482M motherboard.

http://us.msi.com/service/search/?kw=RS480M&type=product

To the right of the yellow RS480M, click on - Download - in blue.
On the next page hover your mouse cursor on the Download tab.
(Overview / Specification / Download / etc.
In the drop down list click on - Manual
Under the subheading - Download - click right on the blue -
E7145v2.1.zip
Now click on the country name nearest yours.

Make SURE there is a green dot on the small circle, to the left of -
Save File. IF not, click in the empty circle to the left of Save File.
This is a Zip file. A Zip file is compressed. It is used to send a large amount of information easily.
The file has to be 'de-compressed', or 'unzipped'.

If you need guidance in doing so post in a Comment.
No problem.

If you need help along the way, I'm right here. Just post in a Comment.
And, oh yeah, I'm 'Windy', as you can see, lol!
I try to detail it as if I'm sitting next to you, guiding you.

After reading an article about Emachines awhile back, I found out the reason you can't find the schematic- it isn't available, as some motherboards are made specifically for Emachines and therefore not distributed, as they might normally be, but again, others are, but you have to identify them and go through another source to get them- Emachines, appartantly, will not supply them. All is not lost, however...all motherboards have, basically, the same hookups and connectors for the power supplies, hard drives, etc.- they are standard. I found a web blog that explains the power switch, reset, and power led, which will help. Here it is: http://www.computing.net/answers/hardware/emachine-power-sitch-wiring/56545.html
This site will explain about the 24 pin connector from the power supply
http://www.tomshardware.com/forum/53750-7-installation-manual-rs480m-w3400-emachine-motherboard
If you google "motherboard wiring" you will find sites that have illustrations of the motherboard, and explain which connectors go to which sockets, and how to identify them.
With a little patience and determination, you should be able to hook everything up from the various blogs on the net. Hope this helps.

eMachines doesn't give out this kind of info, and I don't have one in the shop.
eMachines also had the habit, of using a few different manufacturer's of motherboards. Intel, TriGem, MSI, Asus,and FIC to name five.

Plus eMachines would use whatever was available at THAT moment, when they were producing that particular model line. (Not stating the T2958 specifically. Whatever model line they were making at the time)

Plus at the time the T2958 was made, Gateway had bought out eMachines. (eMachines later bought themselves back)

However all is not lost here. At the time the T2958 was made the motherboards were manufactured by Intel.

The Intel D845GVSR
Uses the Intel D845GV MCH, and the Intel ICH4 southbridge chipset

(MCH. Memory Controller Hub. Intel's naming for their Northbridge chipset)

You are looking to see where the wires go, on the Front Panel header of the motherboard, from the Front Panel of your computer.

(Front Panel header on a motherboard, is essentially where the wires go that come from the Front Panel of the computer. When referring to a connector on a motherboard, a connector is a Header.

The Power On switch wires, HDD Activity Lamp, Reset switch, {If used}, and Power On Lamp, are located in the Front Panel, for your computer)

{Front Panel = 'Face'}

As stated, eMachines does not give out this info.
I just need your patience, and your eyes. I need you to compare a photo of a motherboard to yours.

When you open your computer case, the side cover should come off of the Left side.
The back of the computer will be to the Left, the front to the right.

The Processor will be at the top of the motherboard, and the Ram Memory slots will be to the right.

Observe the motherboard photo at the top of this page,

http://www.dexplor.com/phpBB2/viewtopic.php?f=13&t=7747553&sid=8fa7e78bbadfbd6fde083b28641248cc

Orient in your mind so that the motherboard in the photo will have the Processor to the top, and the Ram Memory slots to the right.

Should you have no idea of what I'm referring to here, please come back, and state so in a Comment.

The Front Panel header is composed of three individual headers, (Connectors) for this motherboard.

J9F2, J9G1, and J8H3

The J9F2 is for the USB ports used in the Front Panel. We won't be concerning ourselves with this header.

J8H3 is located to Right side of the CMOS battery. It has two pins sticking up.
This is where the Power On LED light plugs into, IF, the Power On LED light has Two wires, and the light is one solid color when lit up.

J9G1 is located below the CMOS battery, and is located on the bottom edge of the motherboard.

There are two rows of pins sticking up.
The rows are parallel to the edge of the motherboard.

The top row has 4 pins.
The bottom row next to the edge of the motherboard has 5 pins.

The pins are numbered from the Left, going to the Right. There MAY be a number 1, or 2, stamped on the motherboard.
I wouldn't count on it.

The top row of pins, going from the Left towards the Right are,
2, 4, 6, and 8.

The bottom row of pins going from the Left towards the Right are,
1, 3, 5, 7, and 9
There is no Pin 10.

1) Pins 1 and 3 are for the Harddrive Activity light. (HDD)
2) Pins 2 and 4 are used for a Power On LED also.
3) Pins 6 and 8 are for the Power On switch

Should you have more questions concerning this, please state so in a Comment.

Here is a link for the manual for your au31 motherboard. The diagram explaining the front panel headers is on page 12.

http://www.lurkhere.com/~nicefiles/AU31_manual.pdf

I found this right on this website, hope it works!
As for the fans, make sure your connections are tight and in the proper sockets.

they have to be plugged in horizontally although it is possible to plug them in vertically because the pins are evenly spaced either way. they are color coded just not like you would expect for example one plug has a green wire and a white wire the green side goes to the green pin and the white side goes to a green pin with a white cross you have to look close because there are several green pins which is what threw me off do this with all three plugs

it varys on each machine , but on the mother board their is a group of pins stickin out one or 2 have jumpers leave them alone! go to the pins left bare their is minenute abreviations next to the pins they will giv you an idea of what 2 do ,also look for colour coding.
