Need front panel pin colour code

I need to know the front panel pin color code. would you know if I am right in my assumption that the following applies. the two green one with a plus on are for either power led or HD led and the two yellow one with a plus sign on is for the same options. Then we have two red which I am assuming is for the power button and two blue which I assume are for the reset. what do you think?

  • Steve Walters Jun 11, 2009

    Hi thanks for the reply.

    Sorry for not explaining properly above it's the pins that are coloured. So anyway I went for it and the original post is correct with the green pins being for the power led.

    Sorted :)

The two green cables are for power LED, one + and one -. Then there are two yellow cables for the HD LED, with one + and one -. The red ones are for ON/OFF (power button), and the blue are for reset. So yeah, you are technically right if I understood what you said xD

Your first clue to going wrong with the repair is that the relay with two extra pins was the wrong type! So you need to look at the old one and read the ratings on it and search the net for one that does match it with the correct number of pins.
As for the resistors you need to read the colour code of them and again search for something the same size. The colour code will tell you the type you need. If you don't know how to read the colour code search on the net for a resistor colour code calculator.
As they look bad I would replace them, even if they did work, they could go dead later.

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!)

For additional questions please post in a Comment.

Front power switch broken. Bezel won't come off easily. Thought we could just get a switch and install on the back but don't know which of the colored pairs of wires go to the original switch in the...

I would suggest this generic Power On switch,

1) http://www.directron.com/atxswitch.html,

and the Red, and Black twisted pair of wires go to the Power On switch.

Your statement of ,"....don't know which of the colored pairs of wires go.....", leads me to believe you may have all of the Front Panel wires disconnected.

How about information as to where ALL the Front Panel wires go?
(Provided I have correctly interpreted your statement)

Back in the time that the eMachines T2542 was made, TriGem was the motherboard manufacturer.

The Model Name of the motherboard is Imperial, and the Model Number of the motherboard, could have been one of four variations offered.

Model Name: Imperial
Model numbers could be G, GL, GV, or GLVE
(Imperial G, Imperial GL, Imperial GV, or Imperial GLVE)

ALL four variations used the same Front Panel header.
(The connector on the motherboard the Front Panel wires connect to, is named the Front Panel header)

I would like you to view this page,

http://www.e4allupgraders.info/dir1/ecase/support/front_panel_header_support.shtml

Scroll down to the heading -
Trigem Imperial Front Panel Header Pinout.

A) Pins 1, 2, and 3 are for the Power On LED light.

B) Pins 5 and 6 are for the HarDDrive activity LED light.
(Pin 4 is not used. NC. No Connection)

C) Pins 7 and 8 are for the Power On switch

D) I wouldn't connect any wires to Pins 9 and 10, nor Pins 11 and 12

E) Pins 14 and 15 are for the Reset switch. (The button you press to restart your computer.
If the T2542 doesn't have a Reset switch, don't worry about it. There are many other ways to restart your computer)

F) Pins 17 18, and 20 are for an internal speaker.
This speaker is used for BIOS Beep Codes.

In the chart to the right, you will see GRD used many times.
GRD stands for Ground.
ANY Black wire in the twisted pair of wires, is a Ground wire.

Most of the eMachines I have worked on, use a Red, and Black pair of twisted wires for the Power On switch.
I could be mistaken on the T2542.

Best method, is to follow the color code of the wires that come from Pins 7 and 8, and be sure.

I have purchased a Thermaltake V3 black case and am trying to install my M2N68-LA motherboard. The motherboard has a combined 9 pin header for power switch, power l.e.d. and hdd l.e.d. which was one plug...

1) The 9-pin header you are referring to, is the Front Panel header.

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

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00906129&lc=en&cc=de&dlc=&product=3397528

The plastic piece on the front of your computer is the Front Panel.
(Sometimes referred to as a Bezel)

Make a drawing, and notes as to where the individual wires go from that Front Panel header plug, (One-piece plug), to the Front Panel.

Follow the wires from the plug to the Front Panel.

Mark down where Each wire goes.

You may have to take components off of the Front Panel, in order to see exactly where Each wire goes.

For example:
You may have to remove the Power On button/switch assembly from the Front Panel.

It may have the Power On LED light, Power On button, (Switch), and perhaps the HarDDrive LED activity light, in this assembly.

The wires are color coded.

Generally, but not always, when two wires are used in conjunction with each other, (Example, Power On switch, or Power On LED light), the wires will be twisted together.

One wires insulation may be of a solid color, and the other wire may be white, with a stripe in the color of the solid wire.

Example: Wire with Red color, and wire twisted with it may be White, with a Red stripe.

See if these two wires go to the Power On switch.
End of example.

Follow each twisted pair of wires back down to the Front Panel header plug.
(One-piece plug)

See which socket holes the individual wires go to.
Mark it down in your drawing, and notes.

Mark where the individual socket holes plug onto each pin, in that Front Panel header. (9-pin header)

When you are finished, you will have a pinout for the Front Panel header on the Asus M2N68-LA motherboard, and will know where the individual wires go from your ThermalTake V3 computer case.

For the LED lights there is a Positive pin, ( + ), and a Ground pin. (Power On LED, and Harddrive activity LED, for example)

(Ground. Also referred to as the Negative pin. ( - )
This is DC Voltage)

If you have the polarity backwards, (Positive wire of the LED light is going to the Ground pin, Ground wire of the LED light is going to the Positive pin), the LED light will be dim.

(When operating)
Switch the wires around.

If you have questions, or need clarification of what I have stated above, simply state in a Comment.

Which connectors are used for front panel, power on (red @white) and led ( blue @ white) please show a close-up view

Hi,
On the motherboard the pinouts on the front panel should be colour coded, and marked with letters like in this picture >>>>>
ce10baf.jpg

The connectors are also marked corresponding to where the connect on the motherboard, like in this picture >>>>>>
66ce2fc.jpg

If the board is not colour coded then the motherboard will marked with the same letters, you may need a strong light to see the marks.

  • USB connector
Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.

Wiring color code sequence for the pins to the front system panel for an asrock p4i65g motherboard. There are 4 double pin connectors. Jim/Sudbury

Can't say what the colours on your case wires are because they do vary but they should be marked up PWR SW (or PWR BTN), HD LED, etc.
Looking at the pin layout there should be a row of four with the pin on the far right missing and underneath a row of five with the last one on the far right being unused.

12 3 4
OOOO
5 6 7 8 9
OOOOO Pins 3 and 4 are PWR. Pins1 and 2 are PWR LED.
5 & 6 are Hard drive and 7&8 are reset
