Hi ford, the most common case colored wires used for negative - is white. The colors blue, red, green are usually positive +. The internal speaker though it uses a 4 pin connector only plugs onto the 2 end pins. Black is connected to negative - pin & red is connected to + positive pin. (Depending on the MB model).
All these case LED's use 5volts DC. If you make a boo-boo, don't freak out. You can usually shut down the system & turn the connector 180 & re-connect it with out hurting the board. Suggest you connect 1 at a time & check in-between each.

Still having trouble, include the name & model number of the MB.
Good luck!
Mike

Photo of the Asus M2N78-LA motherboard,

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c01421635&dlc=en

This photo also shows the orientation (Direction), that the motherboard is sitting in a computer case.

To the very bottom right is the Front Panel header.

The front plastic panel of the computer is the Front Panel.

The area of pins on the motherboard that the cables, (Wires) from the Front Panel connect to, is the Front Panel header. ( F_PANEL )

The Front Panel header, is the black rectangular shaped plastic block, that is sitting vertically on the motherboard.

Has two columns of pins.
4 on the left side, 5 on the right side. Makes it look as though there is a pin missing, at the top left corner.

I'm going to number the pins.

Pins on the Left side starting at the Top, going down;

Pins 1, 3, 5, and 7.

Pins on the Right side starting at the Top, going down,

Pins 2, 4, 6, 8, and 10.


A) Pins 1 and 3 are for the Power On switch. (Power On button)

B) Pins 5 and 7 are for the Power On LED light.
Pin 7 is for the Positive ( + ) wire.
(If the LED light is dim, reverse the wires around)

C) Pins 4 and 6 are for a Reset switch, IF a Reset switch is used. (Reset button)

D) Pins 8 and 10 are for the HarDDrive activity LED light.
Pin 10 is for the Positive wire. ( + )
(If the HDD LED light is dim when operating, switch the wires around)

Pin 2 at the top Right is NOT used. (NC. Not Connected)

For additional questions please post in a Comment.
I am looking at a motherboard manual in PDF file form, for the Asus M2N78-LA motherboard.

Installed gigabit MB new power supply, all new parts and only get flashing lights on the optical drive on boot up any ideas what i could be doing wrong ?


1. Check whether two power connectors are connected (one is 20 pin and the other 4 pin)
2. Remove all FRONT USB, Audio, HDD, CDRom and other connections on motherboard, except the power button connection now turn on.
3. If still does not, instead of Power button use reset button connection for Power button and try.
4. Check whether proper memory supporting type is installed in proper direction, try putting in another slot.
5. Change the SMPS eventhough it may be powering on.
6. Check the Motherboard by keeping it externally taking precautions.

Hi

The wires that read +5 -d +d and ground those are USB connectors each usb connector will have 4 wires, +5 -d +d and ground so that goes to usb pins.

The sw must be power switch
The HDD led is the load light
Reset is the reset button
Power led is the front power light
SPK is the speaker / beeper.

Can you tell me the brand and model of the motherboard? They are documented in the user manual. but generally in the bottom right corner of the motherboard you have the connectors for the leds and buttons, its all written into the motherboard with small white text. but I can get clear instructions from the user manual for you.

You can look for the motherboard details between the expansion slots and between the cpu and memory.

Thanks,
Ekse

Front panel connections


Hi sjcrofts,
The most common problem for most people is knowing what wire color is positive & which wire color is negative. The colors blue, red, green, light blue, light red & light green are normally positive. The color white & black are negative. Your board uses only 2-pin connectors. The 3-pin power connector can be turned into a 2-pin connector to work with the M848ALU pins.
(Page 13, PANEL1). How to? Take the three pin connector, on the back side of the connector you'll see a small tab that holds the wire into the connector. Use a needle & pull tab up while pulling the wire out at the same time. The wire should slide out. Insert the wire back into the connector next to the other wire. You do not need to hook up the SUS led which stands for suspend.

dff74fa.jpg

Pin 1 is positive & the manual shows this by adding the _P = positive.
Pin 3 which is to the right of pin 1, is negative for the hard drive led. Pins 9 & 10 are not used.

Good luck sjcrofts!

the pin arrangement is 4 pins and pins.
From left top row (4 pins) first 2 are power led, next 2 are power switch, next 1 is empty
from left bottom row ( 5 pins ) first 2 are hdd, next 2 are reset, next 1 is empty.
The connectors for the power led and the hdd produce a light, if they don't produce a light, power off your pc and switch the cables round the other way and power on again.

Gigabyte GA-8INXP Motherboard Problem- front connector pins


If the wires from the reset switch is white/blue the blue wire is positive, Hdd red/white red is positive power Green/white Green is positive etc. The wires on the speaker connector will be red/black/black/white - red is positive. The colored wire is always positive. On all GA mb's the positive connection is always towards the back of the MB and are marked with a + on the base of the pin as you can see on the photo. Hope this help.

No boot or wake up


Chances are you need to change the power supply,, but first you need to check to see if its workingm this is quite easy

1.) unplug it
2.) remove the power connector from the main board
3.) on the power connector is a green wire(ONLY ONE) and right next to it is a blact wire(any black will work)
4.) use a peper clip or unisulated wire to bridge the green and black wire by inserting it into the jack contacts.
5.) plug in the power supply, if the fans spins then its working..

If the power supply is fine then you will need to check the power button connectors *wire from power button that connects to the main board),, if the connection is fine, then unjack the connectors and use a bladed screwdriver to bridge the pins for the power button connector on the main board,it should boot up. If not then you need to have that mainboard replaced

Power for HP554e


I will try to help you. Locate a 10-pin connector below your backup battery. This connector has only 9 pins. It has four pins on the top and 5 pins on the bottom. Connect connector from your power button to the top row pins 6 and 8. Look at the diagram below I marked connection points with the “+” sign.

2 4 6 8
0 0 + +
0 0 0 0 0
1 3 5 7 9

Just for your references. Pins 2-4 for Power LED, 1-3 for Hard Drive LED, 5-7 for Reset Button.

How to connect front pannel


How about a picture? Pg. 46 in your manual.
Need manual, download from Intel. (Click on link).
http://www.intel.com/support/motherboards/desktop/RC440BX/sb/CS-013608.htm

0d7be67.jpg
Intel RC440BX Specification
Pg. 46
Basic rules case wiring. The color black is considered ground -. Power wires + can be any other color including stripped wires. (This is standard but case Mfg change to their own specification).

Pin 1 is + power for LED Hard drive green LED, Pin 2 is -/ground for Hard drive LED.
(Pin 3 is + power for LED Hard drive yellow LED, Pin 4 is -/ground for Hard drive LED).(See more options on pg. 47).
Pin 5 is + power for case On/off button, Pin 6 is -/ground On/off button.
Pin 7 is + power for Reset Switch, Pin 8 is -/ground for Reset Switch.
Once positive & negative pins has been located each connector follows in suit.

The Intel RC440BX front case connector is in an odd location.
The user will find it hard to connect front case LED connectors while the board in installed into the case.

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
