Hi Andy
I have just been looking up audio connectors on intel website
http://www.intel.com/support/motherboards/desktop/sb/CS-020642.htm
This information may help you with your problem. I have not read through it all yet as I have a similar problem with a board I am trying to fix at the moment, but you could give it a try.

Dell motherboard diagram of wiring and front pannel connectors


most front panel connectors with a 4 x 5 pin configuration are intel compliant, and are all the same.
The "nine" pin is missing, and is the "KEY" to orientation, no matter which way the pins are situated on the board.
1 3 5 7 X
2 4 6 8 10

1= HDD LED+, usually green
3= HDD-, usually white or black
2= PWR LED+, usually red
4= PWR LED-, white or black
These are polarity specific, and must be connected to the proper + and - terminals to work properly

5= RESET
7= RESET
9 is missing, can be used to determine location of other pins
6= PWR
8= PWR

Thes are momentary contact pins, can't get them backwards

Pins 6 and 10 are jumped together in the Dimension 2400.

Need circuit diagram for HP m8100 GC673AA


HP Support > Pavilion Media Center M8100n Desktop PC > Main Support page,

http://h10025.www1.hp.com/ewfrf/wc/product?product=3440614&lc=en&cc=us&dlc=en&lang=en&cc=us

Product information > Product specifications > Motherboard Specifications, MCP61PM-HM (Nettle2 {HP name} ),

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01077676&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3440614

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.

(Be SURE to FOLLOW Anti-Static Precautions)

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 >>>>>

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

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.

M/b probs


if you are having problem in connecting the front panel i can suggest you you can make out on the motherboard where the F_panel pins are they will be in the order as follows
+ 1 2 +
- 3 4 -
+ 5 6 +
- 7 8 -
9(no connection Pin)
the front panel connections are made in this way
(13)(56)(24)(78)
the frontpanel connections has two wires each for P_sw,Hdd_led,P_led,Reset among these two wires black and white are negatives
so when you connect P-sw you have to see that the positive colour goes for positive
but you have try out which pair of wires are for power switch which you do by removing all the front panel connections and try it with all the four set of pins and check if the system gets switched on in the same way you can find the Hdd-led, reset and P_led

Hi i have a problem connecting the front pannel mic and standard audio connections to my winfast k8m890m2ma motherboard the manual shows where the 8 pin "front audio connector" is like this...


It is a bit of a problem when you have single connectors but here goes. You use the Front Audio connectors. The manual says you have :::.:
If you turn the board round until the dots are the same way round as above. Working from left to right.
Bottom row. MicIn, MicBios, SpkoutR, empty,SpkoutL
Top row GND, empty, returnR, blank space, returnL. Now this is the tricky bit. Try the power if it works OK. Because the board and the case manufacturer work to different descriptions, try this as an alternative. You may have to swap over the two connectors for GND and Mic Bios.
