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.

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.

You can download the manual for you're AOpen MX4GE motherboard from the link provided below; ftp://ftp.aopen.com/pub/manual/mb/mx4ge/mx4ge-ol-e.pdf
You'll need Adobe reader installed to view the *.pdf file above.
Download Adobe @ http://www.adobe.com/products/reader/
Open manual to page 33. Here you'll see the layout for the front panel motherboard pins. The view towards the left shows where to connect the jumpers coming from the case to the motherboard. The view on the right shows where each positive wire and negative wire connects. The common colored wire for each jumper will be used as negative. Except for the internal speaker 4-pin jumper. Normally positive wire is red in color and ground is black in color and connects to pins 16 and 19 only. Pin 1 is shown. Pin 2 is to the right of pin 1. Pin three is below pin 1 ECT.

If you no longer have the manual for you're Intel D815EEA motherboard, open the link provided and download it; http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=17793&ProdId=385&lang=eng
You will also need Adobe reader installed to view the manual; http://www.adobe.com/products/reader/
Read over pages 65 to 68.
Once completed turn to page 68 Figure 23. Front Panel connectors. Figure 23 shows two views.
View - (left figure), shows J9C1 as you look down at the front panel pins. The right figure will not be needed. Connect each jumper or each pair as shown.
Wire colors are important and do vary from case to case. The common color of each pair will most likely be used for negative. Wire colors such as blue, light blue, green, light green, red and light red are commonly used as positive.
Pin 1 will be positive and pin 3 will be negative. This is letter - C. Hard drive activity LED.
Pin 2 is positive and pin 4 is negative. Case power LED, and so forth.
As mentioned on page 65, the case front panel pins use 5 volts DC. If you make a mistake and place a jumper backwards (No LED light), just power off the switch on the back of the power supply and correct the jumper by turning it 180 deg. If you’re case’s LEDs do not light up than you will need to connect letter G and letter H. The electronic circuits under the motherboard should supply all 16 motherboard pins with the 5 volt DC and ground needed.

I'll help you with this issue but it is advised you download the manual for the Intel D845GVFN MB. The manual is in pdf format. You'll need Adobe reader to view the manual. Adobe reader is free. Open the link for Adobe, download and install it; http://www.adobe.com/products/reader/
Provided next is the manual link from Intel; http://downloadmirror.intel.com/15211/eng/D845GVFN_ProductGuide_English.pdf
See page 11, Item O. See page 12 for description. (Auxiliary front panel power LED connector). If you setup the Front Panel Header as shown on page 31 item C. You shouldn't need to connect item D, Alternate power LED. If you're board does not power up than do connect item D.
Pin one should be positive and pin two should be negative. The wire colors define + and -. Wire colors do vary from case to case. Normally colors as red, blue and green are found to be positive. The color white and black are common for ground -. Check item C. You'll find a common color for each connection. This common color is ground.
On the odds if after you connect item D fails you can switch off the PS and switch the connectors. Item D and C use 5volt DC. A few seconds in the wrong position will not damage the motherboard.

Good luck
Mike

Hi hickoryhi138,
The motherboard your referring to is made by Mach Speed.
Click on the link provided & scroll to the bottom of the link to download the manual; http://www.machspeed.com/specs/MSNVspecs.pdf
Drivers are also listed on the link.
For the manual (Only), click on the next link; http://www.machspeed.com/manuals/MSNV-939manual.pdf
Go to page 19, Header for Front Panel Facilities: JPANEL1
Knowing what wire color is positive & which is negative varies from case to case. Check the group of front panel wires. Most likely one wire from each 2-pin connector will share the same color. Like the color white which is common for ground/negative. Other colors, blue, green & red are commonly positive. The only exception is the speaker wires. Mach speed only uses two wires across four pins. Black is most common for ground & red is for positive.

Good luck hickoryhi138!
Thanks for using FixYa.

Assuming that the computer is laying down on it's right side, and you are viewing the F panel (the front panel header) from the right side of the motherboard (the bottom of the computer), pin 1 is on the bottom left of the F panel, pin 2 is on the top left, pin 9 is on the lower right, and pin 10 is on the top right (no actual pin)...

1 HD_LED_P Hard disk LED (+) 2 FP PWR/SLP *MSG LED (+)
3 HD_LED_N Hard disk LED (-)
5 RST_SW_N Reset Switch (-)
7 RST_SW_P Reset Switch (+)
9 RSVD Reserved
4 FP PWR/SLP *MSG LED (-)
6 PWR_SW_P Power Switch (+)
8 PWR_SW_N Power Switch (-)
10 Key No pin

Usually the wires and the pins are color coded, (the colored ones being positive.) Sometimes the connections are written in very small abbreviations on the motherboard.

Hello davideiker1, the Intel D845GRG MB manual is shared with another Intel board. (D845GBV MB). Go to this Intel site & download the D845GRG manual; http://support.intel.com/support/motherboards/desktop/d845grg/sb/cs-008873.htm You'll need Adobe reader to view the manual. Download Adobe from this link; http://www.adobe.com/products/reader/
See page 9 for motherboard layout.
The front panel connectors are shown on page 68, see item C.
On page 69 is, Table 31 shows the pin assignments for the front panel header. Front Panel Header (J9G1).
Pin 1 is power for the hard disk drive led, pin-3 is negative for the hard disk drive. Wire colors coming from the case are important. Look at all of the front case wires. The common color for each 2-pin connector will be ground. In most cases the ground wire is white, except for the internal speaker. Ground for the speaker is normally black. (This motherboards speaker is built into the MB, no hook up is needed).
Pin number 2 is positive for the case power led which lights up as green. Pin 4 is negative for the power led.
The reset switch is a bit different. Pin 5 is negative & pin 9 is positive, however if your case uses a two pin connector than connect pin 7 as ground & pin 9 for positive. The On/Off switch, pin 6 is positive & pin 8 is negative.
If this manual is not what you see on the MB, please advise.

Good luck davideiker1!

Hi Billy, please use the manual to help guide you. Turn to page 33. If you no longer have the user manual please download it from this link: http://download.intel.com/support/motherboards/desktop/d865gvhz/sb/c70845001.pdf
You will need adobe reader to view the manual. You can down load adobe for free at this link:
http://www.download.com/Adobe-Reader/3000-2378_4-10000062.html?hhTest=1
Or directly from Adobe. http://www.adobe.com/products/acrobat/readstep2.html

On pg. 3 is a picture of the motherboard's front panel pin connections. Item "C". (Front Panel pin to case LED's).
Armed with this information (Pictures), you can plainly see the pin numbers.
Page 4 shows you which is positive + & which is negative - pins.
Do not be fooled by the manual name. Intel often groups like motherboards into one manual. This manual does cover Intel's D865GV & D865GVHV motherboard. The second toughest thing to do is find which case wires or positive & which are negative.
This changes from case to case. Look at all your front panel wires. Most common ground is white in color. Positive wires are colored except internal case's speaker 2 wire. Black is negative.

Good luck Billy!
Hope you find this helpful.

Hi big_cool, do you still have you're manual for the A8N-SLI board? Go to page 2-29. The ground is clearly marked in the manual. Wire colors are different from case to case. Black & white are commonly known as ground. Every case connector will have one wire color in common. The common wire will be positive +. The speaker connector uses to wires in a four pin connector. Red is positive & black is ground.
This pic (below), has been blown up to help you see. EX: The hard drive LED + sits on far left edge. Bottom row. The ground is the next pin to its right. Up on the top row. Left edge pin is the positive pin for the PLED = Power LED. Skip one pin to the right & the next pin, (Third from the left) is the ground for PLED.
This should help you get the rest of you're case LEDs connected.

Good Luck!
