    I have a emachine T3830 that had a bad switch or power supply. Wires that connect the power switch and reset and hdd led were pulled and I do not know where they go back.Need to verify that the switch is good. I have already swapped power supply witha known good one. Mother board light comes on but no juice to motherboard. Any help???

  • jamco Nov 17, 2008

    Yes I am a tech, and unfortunately the wiring you sent is not the one for the T3830 .I have two connections ,one says "front panel usb" and the other says "front panel hub". The front panel usb is connected...the front panel hub is not and I do not think that is where the power switch and reset go to.I would appreciate any help...

  • jamco Nov 17, 2008

    model number is TGSR44B18067 AA C79792-103...I hope that helps.Is it not true that if the power switch is not hooked up correctly it will not come on ???BTW a flashlight and magnify glass is indeed a must...

    The Front panel header is usually located on the left corner of the motherboard. If you have the PC laying in front of you with the front bezel facing you. Look down and you will see the front panel header along the edge of the motherboard. Use a flashlight and or a magnify glass (which I always use) to look down and find it.

  • JDTec
    JDTec Nov 17, 2008

    Also, look down on the motherboard and tell me what model of board it is. Moedl # should be white lettering.

  • JDTec
    JDTec Nov 17, 2008

    The polarity on the power connection does not matter. I usually take a flat head screwdriver and short the two power pins on the header to see if the PC powers up. If it does then it's the switch if it does not then it's the main bd. I will search for the diagram of you board now that I have the model.

Motherboard


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.

What you are asking for is a Front Panel header pinout.

I do not have the exact Front Panel header pinout, for your motherboard.
Tell you what I do have though..........

Looking at the Front Panel header on the Ebay link, for the Winfast 760m02-GX-6LRS; the Front Panel header looks to be below the CMOS battery, and close to the Bottom edge of the motherboard.

(Motherboard installed in computer case)

Black rectangular strip of plastic, with contact pins sticking up.
Also looks to be a GENERAL set-up for all Winfast motherboards.
(COULD be wrong here)

This is what I am referencing off of,

http://www.devhardware.com/c/a/Motherboards/Foxconn-Winfast-NF4SK8AA8EKRS-Motherboard-Review/3/

Go to the third photo down. Here you see the Front Panel wires, connected to the Front Panel header; on the motherboard.
(Below round CMOS battery)

Note that the contact pin on the Bottom row, and all the way to the Right; is NOT being used.
(I'm using a 26 inch HDTV as my primary monitor, so it may be easier for me to see)

Now look at this Front Panel header pinout, for another Winfast motherboard,

http://www.techsupportforum.com/forums/f15/winfast-mobo-front-panel-connection-558456.html

(Scroll down a little)

PWRLED is for the Power On LED (Light)
PWRSW stands for Power On switch
HD-LED stands for the HarDDrive activity LED (Light)
RESET stands for a Reset switch, IF USED.

Note where it has a Positive ( + ) sign, next to the pin for the PWRLED.
This is the pin the + wire from the Power On LED connects to.
It is the SAME for every LED that connects to the Front Panel header.

Let's number the contact pins, to make the explanation easier;
Starting at the Left side, Top row; going towards the Right;
Pins 2, 4, 6 and 8. There is NO Pin 10.

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

Pin 2 is for the Positive wire.
Pin 1 is for the Positive wire
If the LED's are dim, (PWRLED, and HDD LED), OR; the LED's do not light up, switch the wires around.

(Pin 9 is N/C.........Not Connected. This is probably a 5 Volt test point, that was used by the factory)

There is a method you can use though, and find out what the individual contact pins are, in the Front Panel header;

Use an LED with two wires

Computer (Power Supply) plugged into power, go along the top row, and touch two pins at a time, with the two wires of the LED.

Example; Pins 2 and 4, as shown in the pinout.
Did the Power Supply come on?
No?

Go to the next two pins. Try again.
When the Power Supply comes on, you naturally know that is the two contact pins; for the Power On switch.
DO NOT touch them again. In fact connect the Power On switch wires.

Power Supply on, computer running;
Now go back along again;
1) LED light blinks?
You have the HarDDrive activity LED, contact pins.
2) LED light stays on?
You have the Power On LED, contact pins.
3) Computer restarts?
Those are the Reset switch, contact pins.

4) Nothing happens?
May be contact pins for a speaker, or contact pins that are not used.
(Speaker is for hearing BIOS Beep Codes.
You have a Piezo buzzer, to the Left of the CMOS battery; for that)

Post back in a Comment, as to the results.

If possible, I would like to ask upon you; to post the Front Panel header pinout; when you find what it is.

That way when a person in the future also has this same problem; the solution will be posted on the internet, for them to find.

For additional questions please post in a Comment.

Front panel connections


I don't find the Front Panel header pinout online, nor do I have an MSI MS-5191 in the shop.

I would suggest using one the LED lights with two wires.
(3-wire is a dual color LED)

There are two rows of pins. Usually the Power On switch, Power On LED, and Speaker; are on the same row.
HarDDrive activity LED, and Reset Switch are on the opposite row.

Speaker has 4-pins designated for it. All the others use 2-pins.
(Unless the PWR ON LED is a dual color jobbie)

Touch two pins next to each other, in the same row; with the 2-wire LED.
Start with finding the Power On switch first.

Usually the top row 1st two pins are Power On LED (Light)
Next in line are the 2 pins for the Power On switch.
Bottom row 1st two pins are usually HarDDrive activity LED (light)
Next 2-pins are usually Reset switch.

May not apply to a motherboard old enough to use a Socket 7 processor socket.
There may be 18 to 20-pins.
Bear in mind that many are not used, and probably 4 are for an internal speaker, for hearing BIOS Beep Codes.
May be two separate Front Panel headers.

Once you find the two contact pins in the Front Panel header, for the Power On switch; I would put the Power On switch wires on.
The small pin connector on the wire/s, will keep you from accidentally touching these two pins again, when the computer is on.

Now you have the two pins for the Power On switch, and the computer is running; then keep touching 2-pins at a time with the LED. (Light Emitting Diode)

LED stays on? You have the Power On LED (Light) pins.
LED blinks? HarDDrive activity LED (light) pins.
Computer restarts? Reset switch pins.

Look for abbreviations near the pins in the Front panel header.

PWR, Pwr, Pwr On, Sw, and SW; are just some of the abbreviations for the Power On switch.

HDD LED, and HDD are two for the HarDDrive activity LED. (Light)
(If it states HDD SW it is the Power On switch. Weird old way of marking)

RST, Reset, and RSW, are for the Reset Switch.
(Reset Button)

If you see 4 pins marked with a bracket ( [ -> Turn so it's horizontal), these are for the internal speaker.

Type MSI front panel connector in your search bar, and look at -> images. See if you can find an image of your MSI Front Panel header pinout.

You can bet MSI carried out that Front Panel header pinout, on other MSI motherboards, besides the MS-5191.

The MSI MS-5191 may have been a motherboard made by MSI, especially for a pre-built computer manufacturer, and not listed on their website as an OEM motherboard.
(Original Equipment Manufacturer)

Won't have the Front Panel header pinout, listed on MSI's support website. (Doesn't)
But you can bet there IS an OEM motherboard made by MSI, that the Front Panel header DOES match.

May be different expansion slots, or motherboard chipset, or whatever; but the same Front Panel header pinout.

Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication that
data is being read from or written to the hard drive. For the LED to function properly,
an IDE drive should be connected to the onboard IDE interface. The LED will also
show activity for devices connected to the SCSI (hard drive activity LED) connector.
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides
power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentarycontact
switch that is normally open. When the switch is closed, the board resets and
runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a momentary-
contact switch that is normally open. The switch should maintain contact for at
least 50 ms to signal the power supply to switch on or off. The time requirement is
due to internal de-bounce circuitry. After receiving a power on/off signal, at least two
seconds elapses before the power supply recognizes another on/off signal

Can't help you.









OH, I'm just KIDDING!

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

On the motherboard the Front Panel header is marked as PANEL1.
Scroll the page down, until you come to Motherboard layout.
Click on the + sign to the left of it.

Shows an illustration of the motherboard.
Bottom/Right corner is PANEL1. The black rectangle that is sitting vertically, in the motherboard photo.

Motherboard installed in computer case, the Front Panel header is two columns of contact pins.
FOUR on the Right side, FIVE on the Left side.

I don't know the actual numbering of the pins, so I'm going to number them myself;

Starting on the Left side at the Top, going down,
Pins 1, 3, 5, 7, and 9.

Starting on the Right side at the Top, going down,
Pins 2, 4, 6, and 8. There is NO Pin 10.

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. If not, do not connect to them.

C) Pin 9 is N/C. Not Connected. It was a +5 Volt power for the factory.

D) Pins 2 and 4 are for the Power On LED (Light)
Pin 2 is for the Positive ( + ) wire.
If the Power On LED is dim when the computer is on, switch the wires around.

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

F) NO pin 10, just a blank spot.

How to find out what wires are what, in that Front Panel harness connector?

Follow the wires from the connector, up to the Front Panel.

Front Panel removed it is easier to see where the wires go.
You can follow the color code of the wires, and see which twisted pair go up to the Power On switch.

You can also see which ones go to the Power On LED.
(Light Emitting Diode, so it is a light)

Reset switch, (IF there is one), same thing.

The only pair of wires that will be left is the HDD LED wires.
HarDDrive activity LED.

The 9-pin plug will have to be CAREFULLY cut apart. Separate the wires, AND their metal terminals. (WATCH your fingers!)

Proper installation of tower wires


According to Gateway Support, the Gateway 505GR desktop computer uses an Intel (Ausberg) 915G motherboard,

http://support.gateway.com/s/PC/R/3724/3724iv.shtml

Intel (Ausberg) 915G motherboard,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

Scroll down to the photo with the sections marked in red.

In the top link, looking at the motherboard with the computer case open, the USB and Firewire (1394a) cables, can be seen attached to the motherboard near the letters D, E, and F.

In F that red cable is a SATA cable. One end attaches to the back of the SATA harddrive, (The angled end), and the other end of the SATA cable attaches to one of those SATA headers on the motherboard.
(SATA header = SATA connector on motherboard)

Preferred SATA header for the Harddrive is SATA 1.
DOESN'T matter though. That's the beauty of SATA. You can plug the SATA data cable into ANY SATA header on the motherboard, and BIOS will find the harddrive.


In the second link, looking at the motherboard photo shown, and comparing it to the view of the motherboard as mounted in the computer case, the Front Panel header is at the very Bottom Right.

Two rows of pins in a White rectangular shaped header,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

(S points to Front Panel header)

[ The plastic front of a desktop computer is the Front Panel.
The area of pins on the motherboard, that the Front Panel wires go to, is the Front Panel header ]

A) Top row has Even numbered pins
B) Bottom row has Odd numbered pins.

http://www.intel.com/support/motherboards/desktop/sb/CS-009016.htm

1) Power LED = Power On LED light
2) Hard Drive Activity LED = LED light that flashes (Usually red in color) when your harddrive is active. Being used.
3) Reset switch = Reset Button. The Reset switch is behind the Reset button. (IF the computer uses a Reset switch)
4) Power Switch = Power On switch
5) Forget about Pin 9. That's for 5 Volts DC - Out. Used by factory.

Which wires coming out of the Front Panel, are the Power On wires, Harddrive LED light wires, Power On switch wires, etc.?

Remove the Front Panel, and trace where the wires end.

IF, the wires already installed coming from the motherboard to the Front Panel, are Too short, you should make notes before you remove them from the motherboard.

Note what color pair of twisted wires, went to where, in the Front Panel.
Compare to the chart of the Front Panel header given above.
(IF any wires are still connected to the Front Panel header on the motherboard)

Once the Front Panel is removed, it's usually pretty easy to trace the two wires up to the Power On switch.
Same for the Power On LED light.
Again, same for the HarDDrive activity LED light.

The SATA harddrive requires a DATA cable, and a SATA power cable.

The connector for a Data cable has 7 contact pins. It is the shorter connector.

http://en.wikipedia.org/wiki/File:SATA_Data_Cable.jpg

The connector can be at a 90 degree angle as shown, or a straight connector.
IF the data cable has an angled connector, it plugs into the Harddrive.
Straight connector goes to the motherboard.

The connector for a SATA power cable has 15 contact pins. It is the longer connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note the L shape of the connectors for the SATA data cable, and SATA power cable.

Also;
This is a 4-pin standard Peripheral power cable. Commonly misnomered as a 'Molex' power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

IF, the SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable.

Using both power cables will burn up the harddrive.
May not happen immediately in some cases, but WILL eventually happen.

Front Panel header:

This link takes you to Intel Support, and the download page for the motherboard manual, for the Intel D101GGC motherboard,

http://www.intel.com/support/motherboards/desktop/d101ggc/sb/CS-021718.htm

On this page click on the blue -
Intel Desktop Board D101GGC Product Guide - English (PDF)

The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name it may take up to 30 seconds before the first page comes up.
It may also take additional time for the file to fully download.

{ Took 7 seconds to download just now, with no additional download time needed.
Using medium speed DSL connection }

Ignore the following if you are aware;
At the top of the PDF file is the PDF file page number box, and the Zoom Out/Zoom In icons.

Zoom Out ( + ) enlarges the page view, Zoom In ( - ) reduces the page view.
For myself I reduce the view size to 100 or 75 percent.

The page number box is to the right of the Down Arrow.

(If you do not see this, hover your mouse cursor towards the bottom/middle. When the icons come up, {They were 'ghosted out'}, click on the PDF icon to the far right )

Provided that somehow you cannot download this motherboard manual;

Orient the motherboard so we are both looking at it in the same direction.

Processor to the Top, Ram Memory to the Right, white PCI slots to the bottom.
The Front Panel header is at the Bottom/Right.

It is a rectangular block of plastic with two rows of pins.
4 across the Top, 5 across the Bottom.

It is numbered Even on the top, and Odd on the bottom.

Starting at the LEFT side going towards the right, on the top row;

There is no Pin 10, just an empty space.

Starting at the LEFT side going towards 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. (Orange)
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. (Blue)

C) Pin 9 is for 5 Volts. Not Used (Black)

Pin 2 is for the Positive wire ( + )
If the LED light is dim switch the wires around.

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

Do not know what wires coming from the Front Panel are the Power On switch wires, Power On LED light wires, or Harddrive activity LED light wires?

Remove the Front Panel, trace the wires to the Power On switch. (Two wires. Probably twisted together. Or all wires are in a single sheath)

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


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)
