The front of your computer is the Front Panel.
The area of pins on the motherboard, that the main cables, (Wires), go to, is the Front Panel header.

Motherboard as installed in computer case;
Processor to the top, Ram Memory slots to the right, white PCI slots to the bottom;

The Front Panel header is located at the Bottom/Right corner.
PANEL1.
Two rows of pins.

(To the left of it is the front panel USB header. USB56. Looks very similar)

Doesn't show numbering for the pins. (Contact pins)
I'm going to number them for easier orientation

The pins across the TOP are numbered ODD.
Starting on the LEFT side going towards the Right;
Pins 1, 3, 5, and 7. There is NO Pin 9.

The pins across the BOTTOM are numbered EVEN.
Starting on the LEFT side going towards the Right;
Pins 2, 4, 6, 8, and 10.

A) Pins 1 and 3 are for the Power On LED (Light)
Pin 1 is for the Positive ( + ) wire.
If the LED is dim when the computer is on, switch the wires around.

B) Pins 5 and 7 are for the Power On switch.

C) Pins 2 and 4 are for the HarDDrive activity LED (Light)
May be marked on the wires as HDD, or IDE.
Pin 2 is for the Positive ( + ) wire.
If the harddrive activity LED is dim when the harddrive is active, switch the wires around.

D) Pins 6 and 8 are for a Reset switch, IF a Reset switch is used.

E) Pin 10 is N/C
Not Connected. (Probably a +5 Volt point for the factory to use)

Have problems downloading, or saving the PDF manual, post back in a Comment.

[CPU = Central Processing Unit. Another term used is Microprocessor, or simply -> Processor, for short ]

The Asus A8M2N-LA motherboard was made SPECIAL for HP.

As such Asus has no info on it.

Looking at the second link posted (Motherboard Specifications), scroll down to the bottom, and click right on - Motherboard Layout

Motherboard layout shown (Direction), is the same as is installed in your computer; Processor to the Top, white PCI slots to the Bottom, Ram Memory to the Right.

The plastic front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the cables (Wires) go to from the Front Panel, is the Front Panel header.

Abbreviated F_PANEL 1, at the bottom right corner of the motherboard, is the Front Panel header.

There are 9 contact pins. Two rows.
Across the Top row they are numbered ODD.
Across the Bottom row they are numbered EVEN.

Coming from the Left side of the motherboard towards the right side, on the Top row;
Pins 1, 3, 5, and 7

Coming from the Left side of the motherboard towards the right side, on the Bottom row;
Pins 2, 4, 6, 8, and 10.

A) Pins 1 and 3 are for the HarDDrive activity LED light.
Pin 1 is for the Positive wire. ( + )
If the HDD LED is dim when operating, switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

C) Pins 2 and 4 are for the Power On LED light.
Pin 2 is for the Positive wire.

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

Hello there
here is a pdf downloadable flile that will help you.
best regards michael

1. [PDF] A7V133-VM 3051k - Adobe PDF - View as html Supports Socket A-based AMD. Athlon™/Duron™ processors. North Bridge ... p.37 System Power LED Lead (3 pin) 22) RESET (PANEL) p.37 Reset Switch Lead (2 pin) ...dlsvr03.asus.com/pub/ASUS/mb/socka/km133a/a7v133-vm/e698_A7V133-VM.pdf

your motherboard only supports USB v1.1, make sure those are they type of connectors on your case, and if so, open this document and go to page 2-16 for diagram: http://dlcdnas.asus.com/pub/ASUS/mb/sock478/p4sdr-vm/e1104_p4sdr-vm.pdf

if the case only has USB v2.0 plugs, you cannot connect them.

you have a panel in the left of your ata connetor in motherboard, read there (is writen f_panel1) for apropriate led place (for example reset is writen rst, power led is writen pwr and disk led hd or hdd.)

[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

it should be in "one group" with power switch,reset switch connector. usually there will be a label on the motherboard ... use magnifying glass if you can't see the small print.

Try donloading this pdf:

It's for asus P4P800-X, but the connections are just the same.

Howzit
Trial n Error is your best bet on the control pins panel there are two rows, with the power plugged in,with a screwdriver touch adjacent two pins together at a time starting with the top row then the bottom row, when you touch the right two pins your motherboard will power-up, then place the power-switch plug onto those two pins (the writing on the plug facing innwards toward the mainboard) the two pins for the reset switch and 99.9% of the time located directly next to the power switch or directly above the the power pins on the other row. For the LED lights you will have to just try the different pins and the Power LED will remain on as long as your mboard is on, but to find the LED pins for the Harddrive you will have to plug in your HDD and then when it powers up try the pins and the led for the HDD will flicker on-off, that would be the correct one. Dont worry your mboard will not be damaged by this in any way. Goodluck and let me know how you go. Thanks
