Motherboard User Manual For SiS965L?


SiS965L is a chipset designation, not a motherboard model number. That said, most motherboards do label the header pins for the front panel connections on the motherboard, though they are a bit small and sometimes are not adjacent to the pins themselves. The Power Switch and Reset Switch pins are not polarized, and when you determine which they are, the connector plug can be installed on them either way. The Power LED and HDD LEDs ARE polarized. The positive pin is marked with a "+" sign and the Green wore of the Power LED and the Red wire of the HDD LED must be on the "+" terminal.

Wiring diagram for on/off button on desktop


Motherboard should have the pins labeled. POW+ POW-

Colored wire is + Black is - although the power switch doesn't really matter. Same with the LEDs they can be reversed and it wont hurt anything or work differently.

Emachine W3410,the main three wire from the motherboard to the power botton on and off switch was remove and iam not sure wish pin they go to .power led, power sw, H.D.D.led,


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.

Wiring diagram for emachine pc 3210 as the wires have been romoved and i dont know where they go back???


Are you referring to the Power Switch, LEDs and such? If so they might be somewhat labeled on the motherboard itself. Or you can try emachines website they should have a manual available I would think.

Please exsplain in what sequence the wires are conected to the motherboard for the front display and operating switch


An Installation Manual for you model motherboard is available at the manufacturers website. MSI will have a picture of the pin designations for SPKR, HD LED, PWR LED, RESET, etc. They all vary from year to year and board to board though. Best of luck.

Need manual to put wiring back correctly please ta muchly


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.

Need wiring diagram for eMachine 20030812 motherboard!!!


You should be able to see the words/letters that go with the jumpers on the motherboard itself. look around the jumper settings area for power, pwr etc. and match them up with your jumpers which should have what the go to on them.

That problem would either be with your video driver or your video card or both.
I suggest looking up your audio device whether it be a card or onboard.
If its onboard, the manual for your motherboard will have it.
Update the drivers.
If its the video card faultering, i suggest buying a new one that fits your motherboard.
The socket size for your video card will also be found in your motherboard manual.

How do hook up front panel power switch to motherboard


The simple way is to remove the front panel of the computer trace the wires to the front panel leds, make note of color pair to each led. The using the manual that came with the motherboard locate the schematic for the JFP1 connector on the motherboard, it show's where the leds wires connect to operate. If you have no manual, if you look very closely at the connector you will see where the led wires connect, you may have to use a magnifiying glass and flash light. You cannot damage anything if you accidently place the led wires in the wrong place. If the panel led wires are in a single connector and won't work on the motherboard, you can remove the wires from the connector by using a very small sharp pointed pick to push down the retaining tab on each wire, thus enabling it to be removed from the connector, just be patient.
