Circuit City and CompUSA both have some excellent techs, many of whom will copy the page of the schematic that you need out of their Service Manual and give it to you.

Hp e93839

~Somewhere, over the rainbow~

My understanding by a search on the internet, is that the HP XW4600, uses a version of an Intel X38 motherboard, and has the ID numbers - model fmb-0702 - on it, as well as - e93839 -

7th post down, - jondvd - 09-28-2008

If this holds to be true, the BLUE header, below the CMOS battery, and close to the outside edge of the motherboard, is ONE USB header.
Indicates Internal.

The Yellow header to the right of it, is the Front Panel USB header.

EACH USB header has contact pins on it, for TWO USB ports.

Does not matter which USB header we are talking about here, on that motherboard.

To identify the pinout, look for the missing pin in the header.
This is the KEY pin.

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,

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,

(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?

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.

Front panel connections

I don't find the Front Panel header pinout online, nor do I have an MSI MS-5191 in the shop.

I would suggest using one the LED lights with two wires.
(3-wire is a dual color LED)

There are two rows of pins. Usually the Power On switch, Power On LED, and Speaker; are on the same row.
HarDDrive activity LED, and Reset Switch are on the opposite row.

Speaker has 4-pins designated for it. All the others use 2-pins.
(Unless the PWR ON LED is a dual color jobbie)

Touch two pins next to each other, in the same row; with the 2-wire LED.
Start with finding the Power On switch first.

Usually the top row 1st two pins are Power On LED (Light)
Next in line are the 2 pins for the Power On switch.
Bottom row 1st two pins are usually HarDDrive activity LED (light)
Next 2-pins are usually Reset switch.

May not apply to a motherboard old enough to use a Socket 7 processor socket.
There may be 18 to 20-pins.
Bear in mind that many are not used, and probably 4 are for an internal speaker, for hearing BIOS Beep Codes.
May be two separate Front Panel headers.

Once you find the two contact pins in the Front Panel header, for the Power On switch; I would put the Power On switch wires on.
The small pin connector on the wire/s, will keep you from accidentally touching these two pins again, when the computer is on.

Now you have the two pins for the Power On switch, and the computer is running; then keep touching 2-pins at a time with the LED. (Light Emitting Diode)

LED stays on? You have the Power On LED (Light) pins.
LED blinks? HarDDrive activity LED (light) pins.
Computer restarts? Reset switch pins.

Look for abbreviations near the pins in the Front panel header.

PWR, Pwr, Pwr On, Sw, and SW; are just some of the abbreviations for the Power On switch.

HDD LED, and HDD are two for the HarDDrive activity LED. (Light)
(If it states HDD SW it is the Power On switch. Weird old way of marking)

RST, Reset, and RSW, are for the Reset Switch.
(Reset Button)

If you see 4 pins marked with a bracket ( [ -> Turn so it's horizontal), these are for the internal speaker.

Type MSI front panel connector in your search bar, and look at -> images. See if you can find an image of your MSI Front Panel header pinout.

You can bet MSI carried out that Front Panel header pinout, on other MSI motherboards, besides the MS-5191.

The MSI MS-5191 may have been a motherboard made by MSI, especially for a pre-built computer manufacturer, and not listed on their website as an OEM motherboard.
(Original Equipment Manufacturer)

Won't have the Front Panel header pinout, listed on MSI's support website. (Doesn't)
But you can bet there IS an OEM motherboard made by MSI, that the Front Panel header DOES match.

May be different expansion slots, or motherboard chipset, or whatever; but the same Front Panel header pinout.

Need IBM motherboard 29R8260 front panel controls


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 need is a Front panel header pinout.

This I do not have. What I do have, is a simplistic method that may allow you to find out, what the pinout is.

Looking at the Hardware Maintenance Manual for the ThinkCentre M51, (It also uses this mobo), the Front Panel header is to the right of the Ram Memory slots. (Processor to the left, Ram Memory slots at the Top)

Looking at the Ebay link, there are three views available. Click on the middle view. In the view photo the Front Panel header is the black rectangle below the Yellow ram memory slots.

Two rows of pins.
Power Supply plugged into power, use an LED light with two wires.
Go across the top row, and touch the first set of two pins next to each other.

No? Go on. Touch the next set of two pins. I'm willing to bet the third set of two pins is the Power On switch pins.
(Could be mistaken, however)

The contact made should be brief. The Power On switch is a Momentary Contact Switch.
Once the Power Supply comes on, wait a minute, then start testing the other pins.

LED light blinks? You have the HarDDrive activity LED pins.
LED light stays steady? You have the Power On LED pins.

Be aware however, that there may be 3 pins for the Power On LED.
Two Positive ( + ) pins, and one Negative ( - ) pin. This is for a dual color Power On LED. (Turbo mode/ Regular mode)
This would mean touching the first pin, or second pin, in the set of 3 pins, and the last pin in the set.

Computer restarts? You have the 2 pins for a Reset Switch.
(Do NOT touch the Power On switch pins again, or the computer may restart)

Not what I would like to state. Would like to state the exact pinout.
Perhaps if you get this figured out, you might take the time to post the pinout. Crude is fine, I can 'clean it up'. This way 100's to 1000's of people may be able to use your findings. Think how many people you would help.

I want to get a usb 3.0 hub and plug it to the asus p8p67 pro on the middle of the mother board. What kind of connection is it?


The header bus above is for the USB Front Panel interface:

This is included in many of the various flavors of the MoBo. If you're looking to use the MoBo connector to supply something other than this Front Panel interface, you're going to need to obtain the pinout of the jack on the motherboard and compare it to the signals required by your USB 3.0 device. The one from Asus is simply gathers the wires and forms them in a single shell - then keys the shell to prevent reverse insertion.

Think of what you have to do as the way USB 2.0 headers are provided on MoBo and the way PC cases have USB jacks built in. The USB header isn't standard; some have 9 pins - some even have 10! They can't seem to get on the same page as to how many pins are needed. The location of the signals on the header are probably different from brand to brand, too. So, the case manufacturers break up all the individual wires and label the signal so that YOU can check the MoBo manual and plug each one in to the correct pin.

M863G V1.5 SW1 header

If your connector on the compaq case is a single conector for all the leads for the switch and LEDs, then make a diagram of how the pinout of the motherboard header, a pictorial or what ever is easiest for you . and label the connections.
Next trace out the wires to the switch and LED on the case and and identify them. use tape to pair them up or label.
I would then remove the wires from the connector and then reposition the the wires to match your header or pinout. That would be one way to fix the difference in pin out between connectors.
The only problem I see is if the new case connector is totaly different and would not plug on the header, unless some modification is made.
