Post the type and model # of your motherboard. I don't think there is any generic way to hook them up. You will need to find it in the manual. Have never seen a MB manual that does not show the pin placements.

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

This motherboard Adam?

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.

How to wire front panal

You will need to open the computer case and check that the cables that run from the actual power button to the motherboard are plugged into the proper spot on the motherboard. Sometimes reseating the cable can fix this issue.

I think this is the link to your motherboard documentation:

Check the page 2-14 or 2-15 and see if that helps you to identify the actual connection for your power switch.

Gateway T2838 with Intel 4000812 motherboard wouldn't power up. Replaced mother board and power supply. New components also won't power up. Both boards have green ready light lit on the board and both...

Check ALL your USB ports.. If any of the USB ports have shorted contacts or if the 5v rails are shorted to ground, the power supply WILL NOT switch on.. Also, if any of the items connected to the board have a supply rail grounded, again the board will not allow boot up. Unplug everything from the board and the drive power connectors too, except the power connector to the board and the front panel switches and try to switch on, if it still will not boot, check and recheck the USB ports and all power connectors, if it does, switch off and plug another item in, then switch on again. When you get to the item which prevents the board from switching on, thats where your problem lies. Dont forget, plug things back in one at a time, including the power plugs to the drives and try and power up between each item, and dont forget to power down after each item has been checked..

Motherboard wont post. This is a MSA2-6100V. Have isolated board to check for shorts, removed and tried posting with each stick of ram,cleared CMOS. Problem is CPU fan runs as soon as you switch power...

Sounds like either the processor is dead, power supply is not supplying all the voltages, especially the processor connector (4 - 6 wire connectory, usually blk and yellow wires), one or more of the onboard voltage requlators has failed.

For faults 1 or 2, you can try replacement parts. For fault 3, best to replace the motherboard

No Post No Beeps just lights and fans

If the computer just turns lights and fans thats because you have a piece of hardware that is unable to start.

My guess is that you burnt one of the three:

The Board
A Card attached.

Disconnect the hard disks and DVD CD drives
Try removing a ram slot at a time and keep trying, keep doing that for all the pieces until you have none.

If at the end (when you get to a part where you only have Board and VGA plugged the computer still doesn't boot up, the best sollution is to try these 3 on another pc to make sure they are faulty before sending them to vendor.

Good luck

Power LED on but no boot up

it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board

Cpu cannot boot

Hi, the most likely place(s) where a spark could occur on your motherboard would be near the processor where the big transistors are, the capacitors. Such if it were the case would mean that your motherboard is most likely fried and therefore would require replacement. Check if there are any burnt marks or try to smell the motherboard. Arcing (spark) would leave a telltale burnt smell within the immediate area. Another likely place would be the capacitors themselves (3300uF/6.3V or something like that). Normal capacitors would have flat surfaced end with an indented X or T mark. If any would show a bulging, cracked, open or blistering open, then chances are they are busted, leaking, shorted - all meaning motherboard replacement. Aside from the motherboard, it might be that the power supply itself is defective. Normally (but not always) spark/arcing would occur in the hotside (the one directly connecting to the mains). You are probably better off buying a new PSu rather than have it repaired. In some cases, PSU with on/off master switch at the back have been known to have arcing/sparking problems. In this instance, switch replacement is possible without replacing the entire powersupply. In extreme cases, the said switch can be left out (removed) and the two wires going to it just twisted together and taped. Again this is on the hotside. If you are not comfortable working with power supplies, may I suggest you ask a competent service personnel to do the repalcement or removal and shorting. Hope this works out for you. Cheers.
