Hi there

I believe I can provide this for you, but with Dell systems I would need to know the model of the Dell system it has come from, such as Dell Dimension 8400 for example.

Please do not rate this reply unless I have answered your question or your reply will not be returned to me. Thanks.

I need a wire diagram for a Gateway Mother board MCP61PM-GM


Carole,

The front of the 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.

Would this be what you require, or more extensive?

From a fellow FixYa expert,

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


I know it states MCP61PM-HM
The 10-pin ( actually) Front Panel header, is the same across the board, for ECS motherboards.

For additional questions please post in a Comment.

Dell case 4600 replaced mother board with gigabyte but front power wiring needs different connection plz show diagram


Pinout (Wiring diagram) for the GigaByte GA-8I865GVME motherboard's Front Panel header,

(Looks like a 1 but it is an 'Eye'. GA-8 i 865GVME ),
{The plastic front of your computer is the Front Panel.
The area of pins on the motherboard, that the Front Panel cables (Wires) connect to, is the Front Panel header }

;Motherboard Manual download page,

http://www.gigabyte.com/products/product-page.aspx?pid=1933&dl=1#manual

Look under the heading - English
Look across from English, and click on the country name nearest yours.

This is a PDF file. After you click on the server country it may take 30 seconds or more, to see the first page come up.
It may also take additional time for the file to fully download.
(Took approximately 30 seconds just now for me. Medium speed DSL connection)

At the top of the PDF file is the page number box. It is to the right of the Down Arrow.
Go to Page 6.

Processor to the top, Ram Memory slots to the right, the Front Panel header is at the bottom right corner.
(F_PANEL)

It is two rows of pins that are laid out horizontally. It is parallel to the bottom outside edge of the motherboard.

Go to Page 22.
F_PANEL (Front Panel Jumper)

The pins are numbered Even on the top, and Odd on the bottom.

Starting at the Left side of the motherboard going to the Right, for the TOP row of pins;

Pins 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20

Starting at the Left side of the motherboard going to the Right, for the BOTTOM row of pins;

Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19

A) Pins 2 and 4 are for the Power On LED light. (On the computer case. Not on the motherboard)
(Pin 2 is for the Positive { + } wire.
If the LED light is dim, switch the wires around )

B) Pins 6 and 8 are for the Power On switch. (Plastic - Power On button assembly has the Power On switch inside it)

C) Pins 10 and 12 are not used. In fact there probably isn't any pins.

D) Pins 14, 16, 18, and 20 are used for an internal 'speaker'. The 'speaker' is used so you can hear any BIOS Error Codes. (The computers way of telling you something is wrong, and an area to look into for it)

E) Pins 1 and 3 are for the HarDDrive activity LED light.
The LED light that blinks when the harddrive is active in use.
(Pin 1 is for the Positive wire)

F) Pins 5 and 7 are for a Reset switch, IF USED.

G) Pin 9 is NC. Not Connected


To Add:
1) If the Dell Dimension 4600 power on LED light has 3 wires, it is a dual color LED.
Only use two of the wires, and one color.
(Follow the wires to the LED light. One is a Ground wire { - }, and the other two are positive wires for the dual colors of the LED )

2) The Front USB headers are on Page 24

Make sure your Power Supply has a 4-pin ATX +12 volt power cable. Plugs into the square connector on the motherboard, to the bottom Left corner of the Processor socket.
It is power for the Processor.

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

CAUTION!!

For a time period Dell was really @nal about being a Proprietary computer manufacturer.
This means they wanted THEIR parts used in THEIR computers.
I don't know if your Dimension 4600 falls into this category, or not.

They switched the pins around in the ATX main power cable connector, on the motherboard.
Go to Page 18.
Look at the connector that has 20 socket holes. (Two columns of 10 socket holes)

The Dell Dimension 4600 also has a 20-pin ATX main power cable connector, on the motherboard,

http://support.dell.com/support/edocs/systems/dim4600/en/4600i/sm/techov.htm#1138239

Scroll the page down a little, look at the illustration for the DC Power Connector P1
See how the power and color of the wires are labeled for each pin in the connector?

Orient the connector by the lock tab on the side of it. Now compare the color chart here for the wires in a standard 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

A) Orange colored wires are 3.3 Volts
B) Red wires are 5 Volts
C) Yellow wires are 12 Volts
D) ALL Black wires are Ground wires
(ALL are DC voltage)

Guess what would happen if a 12 volt wire is connected to a pin that uses 3.3 Volts, or 5 Volts?
Yep, lets the 'Smoke' out of the motherboard.

Guess what would happen if a 3.3 , 5, or 12 volt wire is plugged into a pin that is a Ground wire?
Same thing. Will fry the motherboard. Possibly the Processor, Ram Memory, Harddrive, and so on, also.

Check before you plug in, and turn the computer on.

For additional questions, or to clarify anything I have stated, please post in a Comment.

Hi i have a Codegen model 450x case and i am trying to install a Gigabite GA-P35-DS3R motherboard and am having troulbe with the start switch wires, the cases wires do not matgh the diagram in the...


I'm not sure what you mean when you say the case wires don't match the diagram. You might mean there is already a plug on the end of the wiring, and this plug doesn't match the board header. If you're reusing the case from a name-brand machine like a Dell or HP, this is possible. They often get custom versions of motherboards made, and their front panel connectors are usually a nonstandard layout. On the other hand, in a generic retail case, the front panel wires normally have separate connectors on the ends for the switches, indicator LEDs and any front panel USB and audio jacks.

This is the front panel header diagram I found in the manual for your board (I looked at version 2, but the connections should be the same if yours is a different version):

pgh_pa_guy_3.png

This board has an Intel standard layout for the header. If your wiring has separate connectors, the start (power) switch wires will plug onto pins 3 and 4. I have never seen a retail case come with anything other than a two-pin plug on the end of the power switch.

If you are dealing with a custom plug on your case's wiring, what you can do is remove the pins from the housing. They almost always are held in by a plastic tab on the connector shell that engages a tang on the pin. Use a thin object like a small flat-blade screwdriver or a knife tip to lift the tab and you can slide the pin out. Insulate each pin with small-diameter heat-shrink tubing if you have it, or a layer of electrical tape. (I prefer the heat-shrink tubing, which is neater and more permanent.) Then you can put each pin over the corresponding pin on the motherboard's front panel header. Unless the pins are very loose, they will stay in place by friction. I often use this technique when salvaging a case.

As for the CPU fan, be sure you have the connector over the right pins. Here is the diagram from the manual:

pgh_pa_guy_4.png

You might need to rearrange the pins in your fan power connector if they don't line up correctly. This layout looks a little strange.

Problem with panel front conector in Dell Dimension 2200 motherbo


The following information is to assist you in performing the right connections. You should take precautionary measures such as grounding yourself and completely disconnecting the PC form any source of power.

This picture shows the connector for the front panel power button, reset button, and power and hard disk lights: an 8x2 pin connector with 1 pin missing:



0505a76.jpg
The table below lists the pinouts for the connector. The orientation of this table is the same as the picture above, this shows the top part of the connector. All the pins below pin 8 appear to be non-connected.


f07048e.jpg


Each pair of pins labeled Power and Reset goes to the 2 wires for the corresponding button. The hard disk and power LED wires connect to the corresponding LEDs, you need to ensure the proper polarity of the + and - wires for each LED or it will not illuminate.

The above information is for your information only.
