    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...

  • jamco Nov 17, 2008

    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.

  • JDTec

    The front Panel Header connections are on this link page 51. Under Technical reference >section 2.8 Internal connectors >then page 51

    The actual Front Panel header is on the left bottom under the Front USB header:

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires connect to, is the Front Panel header.
(Power On switch, Power On LED, HarDDrive activity LED, etc)

The Front Panel header is Black, rectangular in shape, and is situated in a vertical position; located in the Bottom Right corner of the motherboard. (Next to the mounting hole)

It is a standard 9-pin HP Front Panel header,

http://h30434.www3.hp.com/t5/Desktop-Hardware/Getting-a-new-case-i-need-Front-Panel-pinout/td-p/842897

Scroll down to the 9-pin Front Panel header photo, and pinout.

The 4-pin side is the EVEN side. Pins 2, 4, 6, and 8. There is NO Pin 10.
The 5-pin side is the ODD side. Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light Emitting Diode, so it is redundant to call it a light)

Pin 1 is for the Positive ( + ) wire.
IF the HDD LED is dim when the harddrive is active, (IN use), 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. Reserved for factory use, and it is +5 Volts.

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

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

Scroll the HP Support Motherboard Specification page down. Click on the + sign next to Motherboard Layout.

Left to Right on bottom edge of motherboard, Internal Connectors;

AUDIO_1 is for the audio ports on the Front Panel.
ATX_IN is where the small audio cable from the optical drive plugs in.
(CD/DVD drive)
IF TWO optical drives are used; the Main, or Primary optical drive, is connected with the small audio cable. NOT the secondary optical drive.

HD_AUDIO also connects to audio ports in the Front Panel.
May be mistaken, but don't believe SPDIF_OUT header is used.
1394A1 header is for the Firewire ports in the Front Panel (1394a)
USB 2 and USB 4 headers are for the Front Panel USB ports.
USB 1 and USB 3 should be for a Card Reader.

Need where the power cables go, and what they look like? Just post back in a Comment.

Wiring diagram for northgate computer


You didn't state the model number, unless that is it in the problem heading, STAX2517C2.

IF, this is the Model Number of the Northgate Desktop PC, it is supposed to come with a Foxconn/Winfast K7S741MG-6L motherboard,

http://www.ebay.com/itm/STAX2517C2-Winfast-Foxconn-AMD-Motherboard-K7S741MG-6L-/380384605182

Click on the photo with SOLD across it. On the next page scroll it down.
There is a main view shown, and separate views under it.
In the separate views, click on the third one from the Left.

http://www.motherboards.org/imageview.html?i=/images/mobot/motherboards/8286.jpg

Looks like the Front Panel header on the motherboard, is an 9-pin unit.
(Down by the round CMOS battery, black plastic rectangular header, 9-pins.
In the photo it is down to the Bottom/left corner )

[ 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.

May be an abbreviation silk-screened on the motherboard next to it.
F PANEL 1, or FRP1, or FP1 ]

Motherboard sitting in your computer case, the Front Panel header is sitting Horizontal, and parallel to the bottom edge of the motherboard.
There are two rows of pins.

4 across the Top row; 5 across the Bottom row.

The best method is to take an LED light with two wires, and touch two contact pins at a time.
I would go across the Top row first.

Start with the first two pins. Then the second two pins.
When you touch the correct two pins, the Power Supply will come on.
(So will the computer)

You now know that this is the two pins for the Power On switch.
Computer running do not touch the two pins again.
Now touch two other pins.

When the LED light blinks, you know you have the HarDDrive activity LED pins.
If the LED stays on you have the Power On LED pins.

If the computer restarts you know you have the Restart switch pins.

This is what I have that seems to be close, for a Front Panel header pinout for your motherboard.

HOWEVER, I would like you to connect the two pins to the Power On switch first. Just those two.
If these are correct there is a 99 percent chance the others are too.

A) Using an LED light will not harm your motherboard. If the computer isn't running, (Power Supply not on), then you will not be touching any 'live' pins on the motherboard.

Just make a brief contact, with the wires to each set of 2 pins. The Power On switch is a Momentary Contact Switch.

Pinout I have;

Looking at the Front Panel header - Top row;
Starting at the Left side, coming across to the Right side;
Pins 2, 4, 6, and 8. Blank spot -> No pin.

Bottom row;
Starting on the Left side, coming across to the Right side;
Pins 1, 3, 5, 7, and 9.

A) 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.

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

C) No pin 10. Blank spot.

D) 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.

E) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

F) Pin 9 is N/C. Not Connected. Probably 5 Volts (DC), and reserved for the factory.

Would appreciate hearing back if this pinout worked for your motherboard.
Also would appreciate if it did not work, and you found out, how about posting back on that also?
A LOT of people would appreciate this information.

How to re-wire a Compaq Presario SR2150NX Case power Switch


The plastic front of your desktop computer is the Front Panel.

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

F_PANEL_1

The Front Panel header contains connections for the Power On switch, Power On LED light, HarDDrive activity LED light, and so on.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00864922&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3339274

(Look at the motherboard photo. The Front Panel header is at the bottom right. Scroll down for the motherboard illustration )

There are 9 contact pins.
4 across the Top row, and 5 across the Bottom row.

The four pins across the Top row are numbered EVEN.

From the Left side going towards the Right side;
Pins 2, 4, 6, and 8. There is NO pin 10, just a blank spot.

The five pins across the Bottom row are numbered ODD.
Pins 1, 3, 5, 7, and 9.

A) Pins 2 and 4 are for the Power On switch

B) Pins 6 and 8 are for the Power On LED

(LED is dim when the computer is on? Switch the wires around )

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

(LED is dim when the harddrive is operating? Switch the wires around)

D) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

How to know which wires are for the Power On switch, Power On LED, and HDD LED?

Follow the wires into the Front Panel. Remove the Front Panel, and follow them.
(Need guidance removing the Front Panel post in a Comment )

For additional questions please post in a Comment.

I need a wiring diagram for a GM5664


Gateway Support > Gateway GM5664 Desktop PC > Downloads and Support Documents,

http://support.gateway.com/us/en/product/default.aspx?tab=1&modelId=2734

Click on the Support Documents tab
(Drivers, BIOS, Applications, Patches, Support Documents, etc)

Click on the blue - 1015004R - Support Documents

Click on Product Views in the list.
Click on Inside View

Go back to the main page
Click on Components
Go to the heading - Motherboards

4006254R - ECS MCP61PM-GM
(AM2 processor socket, MicroATX form factor motherboard)

Gateway Support is of no further help to us. Product Views for the motherboard does not work.

ECS motherboards use a 10-pin Front Panel header, if memory serves.
One pin is not used. (Not there. Number 10 pin)

http://www.ebay.com/itm/GATEWAY-GM5664-MCP61PM-GM-MOTHERBOARD-4GB-Ram-AMD-Athlon-II-Dual-Core-3-0GHz-/360423046239?pt=Motherboards&hash=item53eae33c5f

On the above link scroll the page down, until you come to the enlarged photo of the motherboard, with - Click an Image to Enlarge - under it.
Click on the photo view all the way to the right, on the top photos.

The view shows the 4 orange SATA headers on the motherboard.
(The whitish 24-pin ATX main power cable connector, is shown at the front, with the blue IDE 40-pin header behind it)

To the left of the orange SATA headers (4) is the Front Panel header.
Black rectangular connector with 2 rows of pins.
One row has 4 pins, the other row has 5 pins.

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

Finding where number 1 pin is, is the problem.
Next to the number 1 pin, and silk-screened on the motherboard, is the number 1.

Looking at the rectangular connector (Front Panel header) you will note one pin is missing. This is where number 10 pin would be.

On the opposite side, and opposite end, is number 1 pin.

The pins are numbered Odd, 1, 3, 5, 7, and 9, on the same side.
(Or row)
The pins are numbered Even, 2, 4, 6, and 8, on the other side.
(Or row)

A) Pins 1 and 3 are for the HarDDrive activity LED light.
(HDD LED light)
Pin 1 is for the Positive ( + ) wire.

If the Harddrive activity 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.

C) Pin 9 is Not Connected. N/C. 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 Power On LED light is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch. (Located inside the plastic Power On button assembly. It is an ATX power on switch)

http://www.fixya.com/support/t614458-hp_mcp61pm_hm_motherboard_diagram

As for the orange SATA headers on the motherboard. The SATA harddrive should plug into the lowest number of SATA header.
It may be labled SATA 0, or SATA 1.

The beauty of SATA however, is that you can plug the harddrive into anyone of those SATA headers. BIOS will find the device. (Harddrive)

If you need guidance in connecting any other cables, such as power cables, or optical drives, etc, post back in a Comment.

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.

E-Machines T3508 PC Desktop Motherboard connecting the wires


The eMachines T3058 Desktop PC uses an Intel D101GGC motherboard.

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

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.
Same as it sits in the computer case.

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;
Pins 2, 4, 6, and 8.
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)

D) Pins 2 and 4 are for the Power On LED light. (Green)
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)

Same for the Power On LED light, and the Harddrive LED light.

Need to know where the harddrive, or optical drive plugs in?
Need to know where the power cables from the Power Supply plug in?

Wiring Connections to the Motherboard:

A) Front Panel header: (Panel 1)

The Front Panel, is the plastic front of your computer where the Power On button, HarDDrive LED light, and Power On LED light is located.

The Front Panel header is the connections, or pins, on the motherboard, where the cables (Wires) go to from the Front Panel.

On the motherboard illustration it is marked as Panel 1.
(Down in the bottom right corner)

On your motherboard, Panel 1 (Front Panel header) is Black in color.
As you can see it is a rectangular block, and is placed vertically.
Has 2 columns of pins.
5 in the left column, 4 in the right column.

The Left column is numbered Odd.
Starting at the Top going down, Pins 1, 3, 5, 7, and 9

The Right column is numbered Evenly.
Starting at the top going down, Pins 2, 4, 6, and 8.

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

Pins 5 and 7 are for the Reset switch.
Pin 7 is for the Positive connection. ( + )

Pin 9 is reserved, and may not be used.

Pins 2 and 4 are for the Message LED light. (LED = Light Emitting Diode)
Power On LED light.

Pins 6 and 8 are for the Power On switch.

If the cables (Wires) are not marked coming from the Front Panel, you will have to remove the Front Panel, and trace where they go.

You will be able to physically see where wires go to the Power On switch, Power On LED light, HarDDrive activity LED

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)
