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.

Mike

Hi,

You can download the manual by clicking this link:

http://download3.msi.com/files/downloads/mnu_exe/M7104v1.0.zip

The connections for JFP1 and JFP2 are given on page 13 of this manual.

Hope this solves your problem. Thanks for using FixYa

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.





Front Panel Connectors: JFP1 & JFP2





Good Luck and don't forget to leave a rating.

Thanks Mark

This is MSI/Support and the download page for the MSI MS-7104 V1.0
Motherboard Manual in Zip file form,
http://www.msi.com/index.php?func=downloadfile&dno=4036&type=manual
Granted, it's not the 2.0 version, but the Front Panel header is the same.

Click on the button with the countries name that is closest to you. I clicked on U.S.
If you don't have your downloads set, to download to your My Documents folder, it will go to your desktop.

Double-click on the file name. You will see the Extraction Wizard come up.

Go up to the top left, and click on Extract All Files.
Now you will see a PDF file on your desktop screen, with the file name under it. Double-click on this PDF file.

After you have opened it, and everything is there, you can go back to the Zip file on your desktop screen, right-click on it, and delete it.
Delete it from your Recycle Bin also, or it will be taking up needless room on your harddrive.

Orient the view of the motherboard, so we are both looking at it the same way.
The processor is at the Top/Middle, and to the very bottom right, is the JFP1 header. (Connector on a motherboard is called a header)
Over to the left of the JFP1 header is the JFP2 header. Looks to be about one inch over from the JFP1 header.

We'll start with the JFP1 header.
The JFP1 header has 4 pins across the Top. Then there is a place for a pin. No pin for where no.5 would be.
The JFP1 header has 5 pins across the Bottom.

The pins across the Top are numbered -> 2, 4, 6, 8, and 10, but there is NO, No.10 pin.

The pins across the Bottom are numbered -> 1, 3, 5, 7, and 9

Pins 2 and 4 are for the Power LED light. It doesn't have which pin is the Positive (+) but I suspect it's Pin 2.

Pins 6 and 8 are for the Power On switch. Doesn't matter which way they go, it's a switch.

Pins 1 and 3 are for the HDD activity light. I suspect Pin 1 is the Positive (+) connection.

Pins 5 and 7 are for the Reset switch. (If you have a Reset button. If not, don't sweat it)

Pin 9 is not used.

JFP2 header:
The JFP2 header has 4 pins across the Top. They are numbered
2, 4, 6, and 8.

There are 3 pins across the Bottom.
They are numbered 1, 3, and 5. There is no No.7 pin.

Pins 2, 4, 6, and 8 are used for an internal speaker. This speaker would be used to hear any BIOS Beep Codes. I suspect No. 2 pin is the positive (+)

Pins 1, 3, and 5 are used for the Power LED. I suspect what they're indicating, is an LED used to show Turbo Boost. In actuality I'm not sure. If your Power LED has a connector with three socket holes, it goes here. If your Power LED has two socket holes, it goes to the JFP1 header, and to Pins 2 and 4.
