Connect the front panel leads to the motherboard connector marked "JFP1" using the following pins as indicated by the markings on the motherboard and the front panel leads: HDD LED on Pins 1 and 3; power LED on Pins 2 and 4; reset switch on Pins 5 and 7; and the power switch on Pins 6 and 8.

Good luck.

Look at the pinout of the Front Panel header, of the eMachine W3400's motherboard.

The plastic front of the computer is the Front Panel.
The area of pins on the motherboard, that the cables (Wires) from the Front Panel connect to,
is the Front Panel header.

The motherboard for an eMachines W3400 desktop computer is an MSI ms-7145
(Micro Star International)

Orient the motherboard in your view so that we are both looking at it the same way.
Processor to the Top, Ram Memory slots to the Right, white PCI slots (3) to the Bottom.

JFP1 is the Front Panel header.
(Junction Front Panel 1)

JFP1 is on the Bottom Right corner. There are two columns of pins arranged vertically.
(The JFP1 header runs parallel to the Right side of the motherboard)

The Left side column of the JFP1 header is numbered Odd.
Starting at the Top and going Down, the pins are numbered;
1, 3, 5, 7, and 9

The Right side column is numbered Even.
Starting at the Top and going Down, the pins are numbered:
2, 4, 6, and 8.
There is NO Pin 10

A) Pins 1 and 3 are for the HarDDrive Activity LED light. (HDD)
If the LED light is dim will operating switch the wires around

B) Pins 5 and 7 are for the Reset switch. (Reset button)
> IF Used

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

D) Pins 2 and 4 are for the Power On LED light (If dim switch the wires around)

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

Trace the wires back to the Power On switch. Even if it means temporarily removing part of the Front Panel to see.

Same with the LED lights.
See which wires go to the Power On LED, and HDD Activity LED. (Harddrive Activity LED)

Follow the 3 wires, and tell me where they go to on the Front Panel.
USB port?
Memory Card Reader?
Firewire port? (a1394)

The eMachines W3410 uses an MSI ms-7145 motherboard.
Also known as RS480M

This is MSI Support, and the download page for the motherboard manual, for the RS480M motherboard,

http://www.msi.com/index.php?func=proddesc&maincat_no=1&prod_no=204

To the Right of the photo of the motherboard, you will see a gray bar with, BIOS, Driver, Utility, Manual, and RSS.
Left-click on Manual.

On the next page look under the heading to the right - Document.
Left-click on the blue - E7145v2.1.zip

On the final page click on the country nearest yours.
A small window will come up with the heading -
Opening E7145v2.1.zip

Be sure that Save File has a green dot, in the empty circle to the left.
[If not, Left-click on the empty circle to the left of Save File]
Now click on OK, below.

Where this file will go.
If you Do Not, have your documents set to save to your My Documents folder (Documents for Vista), the file will go to your desktop screen.

In either place Double-click on the file. Now go up to the left, and click on - Extract All Files.
Click on Next, and Finish.

You will now see a PDF icon. Double-click on this icon.
Go to Page 15.

The plastic panel on the front of your computer is the Front Panel.
This is where the Power On switch, Power On LED, and HDD LED are located.

The connector on the motherboard where the cables (Wires) attach to, is the Front Panel header.
The front panel header is a series of pins, sticking up out of the motherboard.

The MSI ms-7145 motherboard, (RS480M) has the Front Panel header separated into two headers.

JFP1, and JFP2

Looking at the motherboard with the Processor socket to the top, and the Ram Memory slots to the right, the JFP1, and JFP2 front panel headers are located at the extreme bottom Right, of the motherboard.

[Use the Zoom In feature (+ at top of file) to enlarge the motherboard layout on Page 15]

Now go to Page 38.
Page 38 shows the connections for the JFP1, and JFP2 headers.

The JFP1 header, and the JFP2 header, consists of two rows of pins in a horizontal column.
The pins are arranged parallel, to the bottom edge of the motherboard.

Right above the JFP1, and JFP2 header may be three pins, with two of the pins have a jumper. We will not concern ourselves with this jumper header (BIOS with Protect Jumper)

The JFP1, and JFP2 headers are close together. There is no separation in-between them.

The JFP2 header is for an internal speaker.
The JFP1 header is for the Front Panel cables.

The JFP1 header pins start from the right side of the motherboard, and go towards the left.

There are 5 pins across the Bottom. (Going from right to left)
There is NO pin, then there are 4 pins across the Top.
(Again, going from Right towards the left)

The top row of pins are numbered Evenly.
The bottom row of pins are numbered Odd.

Starting on the Right side, going towards the left for the Top row of pins, the pins are numbered,
10 (NO pin for 10), 8, 6, 4, and 2.

Starting on the Right side, going towards the left for the Bottom row of pins, the pins are numbered,
9, 7, 5, 3, and 1.

1) Pins 2 and 4 are for the Power On LED.

2) Pins 6 and 8 are for the Power On switch

3) Pins 1 and 3 are for the HarDDrive activity LED

4) Pins 5 and 7 are used for a Reset switch. (If applicable)

5) Pin 9 is not used.

Download the manual for you're MSI PM8M-V motherboard from MSI; http://www.msi.com/index.php?func=searchresult&keywords=PM8M-V&table=download
You will need to download and install Adobe reader to view the manual. Download Adobe; http://www.adobe.com/products/reader/
Open manual to page 9. See Front Panel Connectors: JFP1 & JFP2. There is no need to connect JFP2's Power LED jumper, this is completed at JFP1. Each wire jumper coming from the case will have one wire color in common with all connectors except the speaker jumper. That common colored wire will be use as negative.
The speaker wire commonly as red is positive and black is negative.

Here is a link to MSI for your MS-6378 Manual.
http://www.msi.com/index.php?func=downloaddetail&type=manual&maincat_no=1&prod_no=283
The file is in .zip format and will need to be extracted to view its contents.
Connector JFP1 pins 6 and 8 are for the on / off switch. Pin 6 is power switch high reference pull-up. Pin 8 is power switch low reference pull-down to ground. Information from page 2-17 in the manual.

The connectors you are referring to, are the Front Panel connectors. The wires come from the Front Panel, where your Power On button is.

The pins on the motherboard are called Headers.

Your Power On switch, (It's behind that button), the Reset switch, Harddrive Activity Lamp, (Light), and so on, connect to the Front Panel headers on the motherboard.

That explained, let's continue;
This is in reference to the MSI K9N6SGM-V motherboard. If this is not the model of your MSI motherboard, come back with an additional comment, and state the Model Number.

The link below is to MSI Support, and the download page for the ->motherboard manual. It is a Zip file. I'll explain how to open that file.

http://www.msi.com/index.php?func=downloaddetail&type=manual&maincat_no=1&prod_no=1086

(Copy and paste the above link into your address bar, then press the Enter key)

Under the Download heading on the right, click on -> M7309v1.1.zip
(It's in Blue)
On the next page I recommend clicking on -> U.S, in the blue button.
A small window will pop-up. Left-click on the small empty circle to the right of -> Save.
Now, if you do not have your downloads set to go to your My Documents folder, (Start>My Documents), this will go to your desktop screen.
Minimize all windows that are open, to see your desktop screen.

On your desktop screen you will see a new yellow folder, with ->M7309v1.1.zip, underneath it.
Double-click on it. In the next window go up to the top left, and click on -> Extract all files. In the next window click on ->Next, then click on Next again.
(Same thing if it's in your My Documents folder)

Now click on-> Finish. You will now see a PDF file with -> 7309v.1.1(G52-73091X2).pdf
Double-click on that file name.
You will now be looking at the Motherboard Manual, for your MSI motherboard.

Page 7 shows your Front Panel headers. There are two of them. JFP1, and JFP2. (Junction Front Panel 1, and Junction Front Panel 2)

JFP1 is on the bottom right. There are 5 rows of 2 pins each. The pins go down in a column. There is NO pin on the top Left of the column.

JLPC1 is a header to the immediate Left of JFP1. (It has 7 rows of 2 pins, but 1 pin is missing 3 over from the right side, and on top) Disregard the JLPC1 header. The JFP2 header is to the Left of the JLPC1 header.
It has 5 rows of 2 pins, with NO pin in the bottom right corner.

At the very bottom of Page 13 it shows you where your Front Panel connectors go.
(When I refer to the page numbers, look at the very top of the PDF file in the Square box. The Square box is to the right of the Blue Down Arrow.
I am not referring to the page number on the page itself)

Use the Additional Comments if you have further questions about this.

Hi ramjet007;

This is strange because MSI doesn't have information on the 7548, since it was made directly for HP. Here is a diagram of another MSI similiar and usually they have their pins on their jumpers pretty much the same. You would use JFP1, And Pin's 1&3 would be the hard drive, 2 & 4 would be the LED, 6 & 8 would be the power switch, and 5&7 would be the reset switch. I know your motherboard is setup differnently, but your JFP1 should be in the right hand corner all by itself.
