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.

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.

Proper installation of tower wires


According to Gateway Support, the Gateway 505GR desktop computer uses an Intel (Ausberg) 915G motherboard,

http://support.gateway.com/s/PC/R/3724/3724iv.shtml

Intel (Ausberg) 915G motherboard,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

Scroll down to the photo with the sections marked in red.

In the top link, looking at the motherboard with the computer case open, the USB and Firewire (1394a) cables, can be seen attached to the motherboard near the letters D, E, and F.

In F that red cable is a SATA cable. One end attaches to the back of the SATA harddrive, (The angled end), and the other end of the SATA cable attaches to one of those SATA headers on the motherboard.
(SATA header = SATA connector on motherboard)

Preferred SATA header for the Harddrive is SATA 1.
DOESN'T matter though. That's the beauty of SATA. You can plug the SATA data cable into ANY SATA header on the motherboard, and BIOS will find the harddrive.


In the second link, looking at the motherboard photo shown, and comparing it to the view of the motherboard as mounted in the computer case, the Front Panel header is at the very Bottom Right.

Two rows of pins in a White rectangular shaped header,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

(S points to Front Panel header)

[ The plastic front of a desktop computer is the Front Panel.
The area of pins on the motherboard, that the Front Panel wires go to, is the Front Panel header ]

A) Top row has Even numbered pins
B) Bottom row has Odd numbered pins.

http://www.intel.com/support/motherboards/desktop/sb/CS-009016.htm

1) Power LED = Power On LED light
2) Hard Drive Activity LED = LED light that flashes (Usually red in color) when your harddrive is active. Being used.
3) Reset switch = Reset Button. The Reset switch is behind the Reset button. (IF the computer uses a Reset switch)
4) Power Switch = Power On switch
5) Forget about Pin 9. That's for 5 Volts DC - Out. Used by factory.

Which wires coming out of the Front Panel, are the Power On wires, Harddrive LED light wires, Power On switch wires, etc.?

Remove the Front Panel, and trace where the wires end.

IF, the wires already installed coming from the motherboard to the Front Panel, are Too short, you should make notes before you remove them from the motherboard.

Note what color pair of twisted wires, went to where, in the Front Panel.
Compare to the chart of the Front Panel header given above.
(IF any wires are still connected to the Front Panel header on the motherboard)

Once the Front Panel is removed, it's usually pretty easy to trace the two wires up to the Power On switch.
Same for the Power On LED light.
Again, same for the HarDDrive activity LED light.

The SATA harddrive requires a DATA cable, and a SATA power cable.

The connector for a Data cable has 7 contact pins. It is the shorter connector.

http://en.wikipedia.org/wiki/File:SATA_Data_Cable.jpg

The connector can be at a 90 degree angle as shown, or a straight connector.
IF the data cable has an angled connector, it plugs into the Harddrive.
Straight connector goes to the motherboard.

The connector for a SATA power cable has 15 contact pins. It is the longer connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note the L shape of the connectors for the SATA data cable, and SATA power cable.

Also;
This is a 4-pin standard Peripheral power cable. Commonly misnomered as a 'Molex' power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

IF, the SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable.

Using both power cables will burn up the harddrive.
May not happen immediately in some cases, but WILL eventually happen.

For additional questions please post in a Comment.

Plugigng of wire in board


Hello there,


Below is an image of *********** Board with number indication and wiring explanation. From your manual page 1-6 you can see the image below and 1-7 for the connector, jumpers, slots. as indicated in your problem I will only answer problems related to the wirings.


pcsyke_115.jpg

  • For the Front Panel


pcsyke_117.jpg
1. There are 8 wires from the front panel's casing, excluding USB connectors and front audio cable.

2. Just plug the front panel switch headers to the F_Panel main board connectors. 1 & 2 are positive, if the led do not light change polarity but Im sure it will.

Note:The mainboard provides a front panel connector for electrical connection to the front panel switches and LEDs. JFP1 is compliant with IntelĀ® Front Panel I/O Connectivity Design Guide.


  • For the USB connectors


pcsyke_118.jpg

1. If your casing has a USB header on the front bezel you can put it on any connector. You can also purchase a USB module cable or an internal card reader and plug the headers to any of those connectors.


Note: Observe Polarity, do this Vcc, -Data, +Data, Gnd ,(NC) ground is always near to NC.

Plug it at your own risk, reference image are already shown.


  • Front Panel Audio connectors


pcsyke_119.jpg
1. Look for FP_Audio header from your casing and plug it to the connector.

*Asus recommend you connect a high definition front panel audio module to this connector to avail of the motherboard's high-definition audio capability.



Hopefully this information helps.

I switched gabinets and the new one has a audio and mic imput on the front and i need to connect them the the MB corectly and idk where to plug them


The PCChips support page for your board is here, where you can download the full manual as well as drivers or other information you may need. This picture shows the front panel audio header location (AUDIO1):

pgh_pa_guy.png

And here is the pin information:

pgh_pa_guy_0.png

I believe the header complies with standard layout, so the plug on the cable to the front panel audio connectors on your new case may fit as-is. Or on many cases the wires have individual connectors on the ends to push over the pins. If yours is like this, you can put them on the correct pins by following the table. The wires are marked with their functions.

Good luck and thanks for using Fixya!

Hello i need to know how to reconnect the computer case wires to a sr1703wm compaq motherboard


Hello.

The Compaq Presario SR1703WM desktop computer, uses an Asus A9AE-LE motherboard.
HP/Compaq's name is AmberineM - GL6E

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00496280&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=1815742

1) I would like to start with the Front Panel wires.
The Front panel, is the plastic front on your computer tower, where the Power On button, Power On LED, and so on is located.

The Front Panel header is the connector on the motherboard, where the cables, (Wires), from the Front Panel connect to.

Looking at the HP Support link above, I would like you to scroll down the page to the illustration of the motherboard, and the photo of the motherboard under the illustration.

Looking at the illustration observe the bottom Right corner.
F_PANEL1 indicates the Front Panel header.

Note there are 4 pins going across the Top, and 5 pins going across the Bottom.

Looking inside your computer, the motherboard will be located in a different position, compared to the illustration.

The Front Panel header will be located Vertically, (Up, and down)

Note that there is a twisted pair of Black, and Red wires.
These wires form the Power On cable.
They come directly from the Power on switch.

There is a twisted pair of Yellow, and Black wires.
These wires form the Harddrive Activity LED light cable.
(HDD)
When the harddrive is active, this LED flashes.

There is a twisted pair of Green, and Black wires.
These wires form the Power On LED light cable.

The wires, (Cables), should be in one Black connector.

Looking at the Front Panel header in your computer, align the Black plastic connector's socket holes, with the pins sticking up out of the Front Panel header, on the motherboard.

Note that the Front Panel header is rectangular in shape. There is 1 pin missing.
The Black connector coming from the Front Panel of the computer, has one socket hole blocked off, to match.

Align the four socket holes in the Black connector, to match the 4 pins sticking up out of the Front Panel header, on the motherboard.

The other 5 socket holes in the Black connector, will match up to the 5 pins sticking up, automatically.

Use care, and you may need a bright light to assist.
These pins can be bent quite easily.
(Also watch your fingers, as the ends of the pins are S-H-A-R-P!)

2) Where it states CLRTC (CLPWD under it), is the Clear CMOS jumper.
Suggest you leave it alone.

3) Where it states F_ USB1, and F_USB2, is where the USB cables from the front of the computer connect to.

(The USB ports on the front of the computer's Front Panel.
F_USB1, and F_USB2 headers on the motherboard, are shown on the illustration to the Left, of the Front Panel header. F_PANEL1)

The plastic connector on a USB cable coming from the Front Panel, has an orientation just like the Front Panel header cable does.

There is 1 pin missing on the USB header on the motherboard.
There is a blocked socket hole in the USB cable's connector.
Align the connector to match the pins.

Doesn't matter which USB cable from the Front Panel, that you connect to the USB headers on the motherboard.
BIOS will find them, and assign an IRQ to each, once you turn the computer on.

All you will see at a first glance is a series of thick Gray insulated cables, coming from the Front Panel of your computer.

If you follow the cables by eye, you can see where the USB cables are connected to the back of the USB ports, on the Front Panel.

You may, or may not, have to remove the Front Panel to see more clearly.

Computer case open, look inside towards the Front Panel.
There is a Green plastic tab towards the Top.

This locking tab is depressed Towards the Inside of the computer, to START to unlock the Front Panel.

Towards the bottom in the same plane, is a Black locking tab. This tab is pulled Towards the Outside of the computer.
There is another Black plastic tab on the opposite side.

At the Bottom are two more Black plastic locking tabs. These are depressed down, towards the Bottom of the computer case.
One on one side, one on the opposite side.

Start by depressing the plastic Green tab, and gently easing the Top of the Front Panel, slightly out.
Then go to the two Black plastic locking tabs located towards the Middle, and depress them.

Ease the top of the Front Panel out a little more.
Finally go to the two Black plastic locking tabs located at the Bottom, and depress them.
Ease the Front Panel off.

(NOTE*
Your computer's Front Panel may not have locking tabs located at the bottom.
Just locking tabs located up from the bottom, more towards the middle)

It's no picnic for your first time, but once you have done it, it becomes easy. (Ummm, Easier!)

4) The Firewire (a1394) cable on the Front Panel, connects to the F_1394 header on the motherboard.
In the motherboard illustration the F_1394 header is located to the Left, of PCI2

Need any further cable connections, post in a Comment.

I need to know where to connect the three seperate 2 pin connectors from the ''power switch'' to the motherboard on my eMachines C2685 desktop computer.


The eMachines C2685 uses an FIC VC37GV motherboard. (First International Computer, Inc.)

http://www.motherboards.org/mobot/motherboards_d/FIC/VC37GV/

Here is the motherboard manual,

http://www.ime.org.uk/pdfs/vc37_vg31_b1_eng.pdf

After you click on the above link, give it up to 30 seconds to download. This is a PDF file.

Barring you cannot download the file, I will state the connections for the Front Panel header on the motherboard.
(Plus state the page to reference to, in case you can download)

View the first link, with the photo of the FIC VC37GV motherboard.

As shown, Processor is at the top, Ram Memory slots are to the right.

The Front Panel header is located at the very bottom right corner.

It is parallel to the outside edge of the motherboard. There are two rows of pins.
(Page 12)

The Front Panel header has 5 pins going across the top, and 4 pins across the bottom.

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

On the Top row starting on the Right side, going towards the left, the pins are numbered 1, 3, 5, 7, and 9.

On the Bottom row starting on the Right side, going towards the left, the pins are numbered 2, 4, 6, and 8.

A) Pins 1 and 3 are for the HDD LED. (HarDDrive activity LED)

B) Pins 5 and 7 are for the Reset switch

C) Pins 2 and 4 are for a Dual Color Power On LED, if used.
Green goes to Pin 2. Yellow goes to Pin 4.

Otherwise Pin 2 is Positive, ( + ), and Pin 4 is Negative. ( - )

D) Pins 6 and 8 are for the Power On switch.
(PWR1, or SW1)

There is a small 3 pin header, just above the Front Panel header. (Page 12)

This is for a Power LED that has either two wires, or three wires.
The pins are numbered from Right to left.

Pin 1 is for the Power LED, and Pin 2 is for Ground, if using a two wire Power LED. (Not dual color)

Pin 1 is for the Power LED, and Pins 2 and 3 are for Ground (GND), if using a three wire Power LED.

Connecting front panel wiring to INTEL 845GRG 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!
