Need circuit diagram for HP m8100 GC673AA


HP Support > Pavilion Media Center M8100n Desktop PC > Main Support page,

http://h10025.www1.hp.com/ewfrf/wc/product?product=3440614&lc=en&cc=us&dlc=en&lang=en&cc=us

Product information > Product specifications > Motherboard Specifications, MCP61PM-HM (Nettle2 {HP name} ),

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01077676&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3440614

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires connect to, is the Front Panel header.
(Power On switch, Power On LED, HarDDrive activity LED, etc)

The Front Panel header is Black, rectangular in shape, and is situated in a vertical position; located in the Bottom Right corner of the motherboard. (Next to the mounting hole)

It is a standard 9-pin HP Front Panel header,

http://h30434.www3.hp.com/t5/Desktop-Hardware/Getting-a-new-case-i-need-Front-Panel-pinout/td-p/842897

Scroll down to the 9-pin Front Panel header photo, and pinout.

The 4-pin side is the EVEN side. Pins 2, 4, 6, and 8. There is NO Pin 10.
The 5-pin side is the ODD side. Pins 1, 3, 5, 7, and 9.

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

Pin 1 is for the Positive ( + ) wire.
IF the HDD LED is dim when the harddrive is active, (IN use), 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. Reserved for factory use, and it is +5 Volts.

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

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

Scroll the HP Support Motherboard Specification page down. Click on the + sign next to Motherboard Layout.

Left to Right on bottom edge of motherboard, Internal Connectors;

AUDIO_1 is for the audio ports on the Front Panel.
ATX_IN is where the small audio cable from the optical drive plugs in.
(CD/DVD drive)
IF TWO optical drives are used; the Main, or Primary optical drive, is connected with the small audio cable. NOT the secondary optical drive.

HD_AUDIO also connects to audio ports in the Front Panel.
May be mistaken, but don't believe SPDIF_OUT header is used.
1394A1 header is for the Firewire ports in the Front Panel (1394a)
USB 2 and USB 4 headers are for the Front Panel USB ports.
USB 1 and USB 3 should be for a Card Reader.

Need where the power cables go, and what they look like? Just post back in a Comment.

(Be SURE to FOLLOW Anti-Static Precautions)

Hi Greeneyedbj,

What kind of I/O connectors are you looking for *********** board sir?

pcsyke_138.jpg

1. Three usb headers up to 6 additional devices, most casing can support 2-4 pins. 2. Front Audio Connector. 3. Front Panel Connector. Power Sw, Reset Sw, Powed Led, HDD Led

Branded casing has the following I/O connectors.

ASUSP4SD-VX Can not figure out how to configure plug for front USB panel to motherboard, when using this mothervoard in a generic case.


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.

TRYING TO HOOK UP MU POWER BUTTON NEED TO KNOW


Hi there
The front panel connectors are mainly,
  • harddisk activity connector
  • power switch connector
  • reset switch connector
  • power LED connector
  • speakers connector
  • USB connector
Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.

Simple pinout help


Front Panel Header pin assignments as follows:

Pins 2 + 4 = Power Led

Pins 6 + 8 = Power Switch

Pins 12 + 14 = LAN Activity Led

Pins 1 + 3 = HDD Led

Pins 5 + 7 = Reset Switch

Pin 9 = +5v

Pins 11 + 13 = ODD Led

Pin formation is as below with no pin in position 10.

2 4 6 8 10 12 14

1 3 5 7 9 11 13

You will probably need to extend the Front Panel connector cable to reach the header pins on a replacement motherboard - I did this with 2 x N76HL 10 pin extension cables (male to female) from Maplin.

Case wiring


For the wires that comes in your CPU casing, mostly used for your front panels like power switch, hdd status, power led, etc. It is indicated on the pins itself so you might not be confused. there are some that comes for front panel USB. (with codes like vcc+ /- ,etc.). The best you can do is to read your Mainboard manual on where you place this pins.
