Foxconn LS36 mobo , front panel (34pin) connection DETAILS needed

Like previous posts , I require the pin allocation on each of the 34 pins on the mobo connector. I cannot get the old front panel and trace back. I only need to know power on and reset connections to test the mobo. Intel / Foxconn manuals and previous links advised don't help.

Motherboard


The front of your computer is the Front Panel

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to; is the Front Panel header.

What you are asking for is a Front Panel header pinout.

I do not have the exact Front Panel header pinout, for your motherboard.
Tell you what I do have though..........

Looking at the Front Panel header on the Ebay link, for the Winfast 760m02-GX-6LRS; the Front Panel header looks to be below the CMOS battery, and close to the Bottom edge of the motherboard.

(Motherboard installed in computer case)

Black rectangular strip of plastic, with contact pins sticking up.
Also looks to be a GENERAL set-up for all Winfast motherboards.
(COULD be wrong here)

This is what I am referencing off of,

http://www.devhardware.com/c/a/Motherboards/Foxconn-Winfast-NF4SK8AA8EKRS-Motherboard-Review/3/

Go to the third photo down. Here you see the Front Panel wires, connected to the Front Panel header; on the motherboard.
(Below round CMOS battery)

Note that the contact pin on the Bottom row, and all the way to the Right; is NOT being used.
(I'm using a 26 inch HDTV as my primary monitor, so it may be easier for me to see)

Now look at this Front Panel header pinout, for another Winfast motherboard,

http://www.techsupportforum.com/forums/f15/winfast-mobo-front-panel-connection-558456.html

(Scroll down a little)

PWRLED is for the Power On LED (Light)
PWRSW stands for Power On switch
HD-LED stands for the HarDDrive activity LED (Light)
RESET stands for a Reset switch, IF USED.

Note where it has a Positive ( + ) sign, next to the pin for the PWRLED.
This is the pin the + wire from the Power On LED connects to.
It is the SAME for every LED that connects to the Front Panel header.

Let's number the contact pins, to make the explanation easier;
Starting at the Left side, Top row; going towards the Right;
Pins 2, 4, 6 and 8. There is NO Pin 10.

Starting on the Left side, Bottom row; going towards the Right;
Pins 1, 3, 5, 7, and 9.

Pin 2 is for the Positive wire.
Pin 1 is for the Positive wire
If the LED's are dim, (PWRLED, and HDD LED), OR; the LED's do not light up, switch the wires around.

(Pin 9 is N/C.........Not Connected. This is probably a 5 Volt test point, that was used by the factory)

There is a method you can use though, and find out what the individual contact pins are, in the Front Panel header;

Use an LED with two wires

Computer (Power Supply) plugged into power, go along the top row, and touch two pins at a time, with the two wires of the LED.

Example; Pins 2 and 4, as shown in the pinout.
Did the Power Supply come on?
No?

Go to the next two pins. Try again.
When the Power Supply comes on, you naturally know that is the two contact pins; for the Power On switch.
DO NOT touch them again. In fact connect the Power On switch wires.

Power Supply on, computer running;
Now go back along again;
1) LED light blinks?
You have the HarDDrive activity LED, contact pins.
2) LED light stays on?
You have the Power On LED, contact pins.
3) Computer restarts?
Those are the Reset switch, contact pins.

4) Nothing happens?
May be contact pins for a speaker, or contact pins that are not used.
(Speaker is for hearing BIOS Beep Codes.
You have a Piezo buzzer, to the Left of the CMOS battery; for that)

Post back in a Comment, as to the results.

If possible, I would like to ask upon you; to post the Front Panel header pinout; when you find what it is.

That way when a person in the future also has this same problem; the solution will be posted on the internet, for them to find.

For additional questions please post in a Comment.

Power front panel conectors on acer 915m08


This Foxconn 915M08-G-8KS motherboard made for Acer Veriton desktop computers?

http://www.sella.co.nz/general/computers/components/motherboards/other-motherboards/b1jnj6/

Do not know what the Front Panel header pinout is.

(Front plastic part of computer tower is the Front Panel.
Area of contact pins on the motherboard, that the wires (Cables) from the Front Panel connect to, is the Front Panel header )

CAN see by clicking on - View full size image - that the Front Panel header is to the Top Left corner of the motherboard, by the CMOS battery.
(View of mobo is upside down, in relation to how it actually sits in the computer tower case)

Shows me it is just the normal two rows of contact pins used in a LOT of desktop computer mobo's. (MOtherBOard)

If it were I, I would use one of the LED lights connected to two wires, and touch across each two sets of pins.

Looking at the motherboard as it sits in the computer case, there is a row of pins on Top, and a row of pins on Bottom.

In your mind start at the LEFT side of the pins at the TOP.
Number them from Left to Right.
Example, Pins 1, 3, 5, 7, and 9.

Now number the pins on the Bottom, from Left to Right,
Pins 2, 4, 6, 8, and 10.

Computer plugged into power, touch the two wires of the LED light, to Pins 1 and 2.
Computer doesn't start? (Power Supply turns on)
Go to the next set of pins.

I am willing to bet Pins 5 and 6 turn the Power Supply on.
No? Keep experimenting.

What will happen if you touch the WRONG pins?
N-O-T-H-I-N-G
You will NOT hurt the motherboard.

When you get to the correct pins, the Power Supply will turn on.
These pins are for the Power On switch.

Now go back through the pins with the Power Supply on, but DO NOT touch the pins that turned the Power Supply on.

When the LED light STAYS on, you have the pins for the Power On LED light.

If the LED light BLINKS, you have the HarDDrive activity LED light.

If Windows starts to load, and you touch the Restart switch pins, the computer will restart over again, and Windows will load again.

(IF this computer has a Restart switch. I do NOT use one, even for the older computers. Just press CTRL, ALT, and DELete keys at the SAME TIME, to restart the computer, or use the Task Manager option)

One pin left all by itself? That is for 5 Volts, and only used by the factory. Leave it unconnected.

There may also be a blank spot on the Front Panel header, where it looks like a pin is missing. This is the KEY pin, and is not used.
It is just to orient where the other pins are.

Worried about getting shocked?
There may be a small spark, as you connect the wires, I will gramnt you that.
But the voltage is 5 VOLTS DC.
In comparison two D cell flashlight batteries produce 3 VOLTS DC.

The harmful AC voltage is contained in the metal enclosure, of the Power Supply. Can't get you unless you pour water on it close up, or stick a metal rod through one of the ventilation holes, in the Power Supply enclosure.

Regards,
joecoolvette

By the by. You could be a lot of people's hero, if you came back, and posted the pins for what they do. Post in a Comment.

Hi, im trying to connect motherboard intel D865GVHZ front panel to connection J9H3, i need a diagram for it. Thank you for your help


I may be confused with your problem you posted mar13974.
I thought Jumper J9H3 was for the Front Chassis Fan.
By your post, it leads me to believe you want the pin assignments for the Front Panel header on the mobo.

At any rate let's go to Intel Product Support, and the download page for the motherboard manual, for the Intel D865GVHZ desktop mobo,
(MOtherBOard),

http://www.intel.com/support/motherboards/desktop/d865gvhz/sb/CS-010872.htm

Click on the blue file name - D865GVHZ_ProductGuide01_English.pdf

After you click you may not see anything happening for up to 30 seconds. The file is downloading in the background.
(Took 16 seconds for me just now with a medium speed DSL connection)

Page 33 shows the location of the Front Panel header on the motherboard.
(C)
Page 34 details the pin assignments

Page 36 shows the Front Chassis Fan header location (Chassis front fan)
3-pin header, doesn't state the pin assignments.
With a 3-wire fan cable,
A) 1 wire is the Power wire. Generally Red
B) 1 wire is the Ground wire. Generally Black
C) 1 wire is the speed sensor wire. Reads how fast the fan is spinning in Revolutions Per Minute
(RPM) Generally Blue, but it's up to the individual manufacturer.

If the above isn't what you had in mind, please state in a Comment.

I can't find where the connections of the front panel are on the motherboard or where they go?


The eMachines T2893 desktop computer uses an Inte G845GVSR mobo. (MOtherBOard)

Intel Support>D845GVSR>Motherboard Manual,
(Intel's name - Product Guide),

http://www.intel.com/support/motherboards/desktop/d845gvsr/sb/cs-008823.htm

I would like you to left-click on the top file.
Click right on - Product Guide - PDF, in blue.

(File name underneath it is -
File Name: D845GVSR_Product Guide_English.pdf )

May take up to 30 seconds, before you see the first page.
(You will be staring at a blank screen until the first page comes up. The file is downloading in the background)

Took 5 seconds before I saw the first page, and an additional 12 to fully download, using a medium speed DSL connection.

The Front Panel header on the mobo is shown on Page 31. (C on the illustration. J9G1 on the mobo)

The Front Panel connections are on Page 32.

Barring that you cannot download this PDF file, or do not understand the manual, I will detail the Front Panel header connections.

Orienting the motherboard so we are both looking at it the same way;

The Processor is at the top, the ram memory slots are to the right side of the mobo, and the white PCI slots are to the bottom.

There are three PCI slots. The one closest to the Processor is PCI 1.
The one closest to the edge of the mobo is PCI 3.

To the far right of PCI 3 is the Front Panel header.
It's the header located closest to the Right side of the mobo, and the bottom edge, and is directly below the
CMOS battery.

There are two rows of pins.
Four across the top, Five across the bottom.

The top row of pins are numbered Evenly.
The bottom row of pins are numbered Odd.

Starting from the Left side of the mobo, going to the right, on the Top row,

Pins 2, 4, 6, and 8. (There is No 10)

Starting from the Left side of the mobo, going to the right, on the Bottom row,

Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the Harddrive Activity LED
If you have a wire with a + sign on it (Positive) it goes to Pin 1.

B) Pins 2 and 4 are for the Power On LED.
(Pin 2 to the Green LED lamp, Pin 4 to the Yellow LED lamp, if applicable with your computer)

C) Pins 5 and 7 are for a Reset switch. (If applicable)
(Pin 5 is Ground)

D) Pins 6 and 8 are for the Power On switch.
(Pin 8 is Ground)

E) Pin 9 is for the +5 Volt power.

(You are following Anti-Static precautions, right?)

Have any questions just post in a Comment.

Proper pin numbers to install inserts in a Dell SATA 34 pin GX270 motherboard


Hi there.
Get a strong flashlight and a magnifying glass (if you have one). On the motherboard look for the front panel, it should be marked PWR and coloured green, also the plug that connects to it should be marked PWR_SW. On some boards there are no colours but the markings are the same, so take a good close look.
Have a look at these pictures for an idea >>>>>>

Unless you have about a $3000 soldering machine and lots of skills soldering, i would say just get a new mobo. the cost to fix it would be lots more than its worth
