Unknown Pin Layout on Motherboard

Top view photo of the motherboard, of an MSI MS-7525 motherboard made FOR HP by MSI, for a Compaq Presario SR5410F Desktop PC,

Also scroll down the page, and click on the + sign to the left of -
Motherboard Layout.

A) 24-pin ATX main power cable:

In the photo, look to the right of the Blue ram memory slots.

The Yellowish/Whitish connector to the right of them, with two columns of 12 socket holes, is where the 24-pin ATX main power cable plugs in.

In the Motherboard Layout it is marked by - ATX1

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

Note the middle photo, and the Lock on the side of the power cable's connector. The Lock has a hooked end that goes over a Tab, on the motherboard's connector.

The Lock works like a see-saw on a playground. The top is squeezed in, and this brings the hooked end away from the Tab, in order to remove the power cable.
When assured that the power cable is plugged in tightly, and therefore correctly, the hooked end of the Lock will be over the motherboard connector's Tab.

B) 4-pin ATX +12 Volt power cable:

In the center of the motherboard, under the Processor socket, is the Northbridge chip. (Part of the motherboard chipset)
It is under a finned aluminum Heatsink, that resembles a meat tenderizer's head.

Draw an imaginary line up above it, in-between the Processor socket, and the aluminum finned Heatsink, and go straight LEFT.
See the whitish 4-socket hole square connector?

In the Motherboard Layout it is marked by - JPW1

This is where the 4-pin ATX +12 Volt power cable plugs in. It is power for the Processor. Has the same locking setup as the 24-pin ATX main power cable, and it's motherboard connector.

C) In the Motherboard Layout to the top left corner of ram memory Slot 1, (DIMM1), is where the Processor fan connects.
CPU_FAN1

D) In the Motherboard Layout just below JPW1 is where the computer case fan plugs into. SYS_FAN1

E) In the Motherboard Layout - SATA1 - is where the SATA Harddrive data cable plugs into. (Below ram memory slots)

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

The SATA power cable from the power supply, plugs into the SATA harddrive. Note that the SATA power cable's connector, is longer in length than the SATA data cable's connector.

[SATA power cable has 15-pin. SATA data cable has 7-pins ]

Note that both cable's connectors, have an L-shape on the inside.

NOTE*
This is what a 4-pin standard Peripheral power cable looks like,

IF, your 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!

Otherwise you will burn up the SATA harddrive. May not happen right away, but I assure you it will happen!

[ A note on SATA.
The beauty of SATA, is that you can plug into ANY SATA connector on the motherboard, and BIOS will see it.

If you plug the Harddrive into SATA 1, or SATA 2, or SATA 3, or SATA 4, connector on the motherboard, IT DOES NOT MATTER.
BIOS will find the Harddrive, or optical drive ]

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.

In the Motherboard Layout illustration, the Front Panel header is down at the Bottom/Right corner, and is marked - JFP1.
(Right in the very bottom/right corner is JUSB2. JFP1 is right above it)

JFP1. Junction Front Panel 1.
9-pin header. Black rectangle.
5 pins on the Right side, 4 pins on the Left side.

The pins are numbered EVEN on the LEFT side.
Starting on the BOTTOM going UP;
Pins 2, 4, 6, and 8. There is NO Pin 10.

The pins are numbered ODD on the RIGHT side.
Starting on the BOTTOM going UP;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED.
(Light Emitting Diode, so it is a 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.

C) Pin 9 is N/C. Not Connected. 5 Volt power, and reserved for the factory to use.

D) Pins 2 and 4 are for the Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR ON LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

You need to get the motherboard number and look it up at the manufacturer site under support you should be able to download a tech specs for that board showing the pin layout [owner manual may have it too.

if you are talking about connecting the front chassis connectors to your motherboard then you need to find out the exact model of the MB... im assuming its Intel since its a Dell.

the link below should get you started

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 >>>>>>




Please post back with the results and any more advice if needed.

Good luck and thanks for choosing FixYa!!

If I understand correctly you are looking for the pin layout to reconnect your front panel cables. Here is the link for the manual for your motherboard which should show you everything you need to know about your board.

http://download.intel.com/support/motherboards/desktop/D845GLLY/ADLY_English.pdf

[10][ 9] Pin 1 = +HDD pin 3 = -HDD LED
[ 8][ 7] Pin 2 = + POWER pin 4 = - power LED (SPD)
[ 6][ 5] Pins 5 & 7 = reset
[ 4][ 3] Pins 6 & 8 = Power switch
[ 2][ 1]


Hope you find this Useful

Hi, There are 3 versions of this motherboard; 1.0, 2.0 & 3.3, but the layout is identical. The general layout is shown in pins.jpg. For the power led, the white wire goes to the (-) terminal either pin 2 or 3, both are MPD- while the green goes to the ( ) or pin 1 (MPD ) as shown in powerled.jpg HDDpins.jpg shows the connection of HDD led, the white goes to pin 3 or HD- while the red goes to pin 1 or the HDD . I cropped these images from the manual which is also available at the gigabyte website. Hope this gives you some ideas and workout of you. Good luck and pls post again how things turn up. Kind regards.
