I am looking for MCP61PM-HM (Nettle) 9 pin front panel power header diagram


This motherboard Adam?

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c00906137

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.

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.

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.

Emachines t3830 I need the schematic for MB I umployed the wire for the push bottom without looking at the way they were plug. Now I do not know the correct aligning of the push bottom wires.


If you look at the motherboard there is usually a diagram labeled "FRONT PANEL HDR" that will tell you which pins are for: HDD LED, PWR LED, RESET, PWR ON. etc.
The chart / diagram may be a few inches away from front panel header.
the following example is from my emachine T2893 that I had opened because it won't power up.

the motherboard at the header connector labels pin #2 and with that you can figure out the other
pin numbers

example of diagram on motherboard (Confirm the pin numbers on your motherboard)


J9G1 PINS
| HD LED | 1 - 3 |
| PWR LED | 2 - 4 |
| RESET | 5 - 7 |

| PWR ON | 6 - 8 |

Hope this helps you figure which pins to hook you switch up to.

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.
