Need diagram for connection on motherboard 4006272r


Gateway 4006272R motherboard;

Foxconn (Bengal) RS780 motherboard.

[ In otherwords the motherboard chipset is an AMD RS780 series,

http://en.wikipedia.org/wiki/AMD_700_chipset_series#780G.2F780V

http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics_processing_units#Radeon_R600_series

Scroll down to the bold black subheading - IGP (HD 3xxx, HD 4xxx ]

This motherboard,

http://support.gateway.com/s/MOTHERBD/Shared/4006272R/4006272Rnv.shtml

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 list click on -> Product Views
Now click on -> S - Front Panel Connector

Motherboard installed in the computer case, the Front panel header is at the Bottom/Right corner.
It has -> F_PANEL <- silkscreened in white underneath it.

Two rows of pins.
The pins on the Top row are numbered EVEN.
The pins on the Bottom row are numbered ODD.

Starting on the LEFT side, coming across to the Right;
Top row;
Pins 2, 4, 6, 8, No pin, 12, and 14.

Starting on the LEFT side, coming across to the Right;
Bottom row;
Pins 1, 3, 5, 7, 9, 11, and 13.

Pins 11, 12, 13, and 14 are NOT USED.

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 the harddrive is active, switch the wires around.
These pins are in the Orange blocks.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.
These pins are in the Blue blocks.

C) Pin 9 is N/C. Not Connected. Reserved for factory use.
Black block.

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

E) Pins 6 and 8 are for the Power On switch.
These pins are in the Red block.

F) There is NO Pin 10.
Black block.

Again, Pins 11, 12, 13, and 14 are Not Used.

B- CPU Power Connector is at the upper left corner of the motherboard. This power cable is power for the Processor.
MUST be plugged in.
A general example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Note the Lock on the side of the power cable's connector, and matching Lock Tab on the motherboard connector.

F- Main Power Connector also has a Lock, and Lock Tab.
General example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

D - CPU Fan Connector is above the processor socket, and near the top outside edge of the motherboard. ONLY plugs in one way.

Installed mother to new tower case and pwr sw | hd led | reset | power led connecting to my board is the Intel dq67sw 155 matx motherboard need accurate dir to connect these please help


info found at http://downloadmirror.intel.com/19707/eng/DQ67SW_ProductGuide01_English.pdf
Front Panel Header Pin info for DQ67SW. They should be color coded too. 1 Hard disk LED + orange
2 Power LED+ green
3 Hard disk LED - orange
4 Power LED- green 5 Reset Switch - blue
6 Power switch + red
7 Reset switch + blue 8 Power switch - red
9 Power Out (do not use)
10 No pin
NOTE When connecting individual wires from your chassis front panel to the front panel header, be sure to observe the connection polarity. Positive wires are usually solid color and negative wires are usually white or striped.
There is also an alternative pin header if you have a power wire that uses a 3 pin connector instead of a 2 pin connector. It is the 3 pins just past pin 9, and it should be missing the pin in the middle of the 3 pin block. The pin closest to pin 9 is the power led + and the furthest from pin 9 is the power led -.
if you need clarification, check out page 50 of the manual posted above at intel.com

How do i wire-up the: ( eg. power l.e.d., HD led, reset led ect. to the board


The various wires from the case front panel should be labeled to indicate power LED, HD LED, etc.
The motherboard front panel jumper pins should be grouped together and the pins should be labeled to indicate PWR, HD. RST etc.
You can go to the motherboard manufacture's WEB site to download a diagram of your model motherboard and it will show all the locations of the connecting pins.

How to connect the front panel sould device?


Do you mean speaker or front panel audio? The front panel audio connector is located at the rear of the board, behind the PCI connectors - the speaker connections are in the panel connector block (2x10 pin header) located at the front left of the board.

With the board in it's normal position, the speaker pins are on the right hand side of that block, on the pin nearest the front and the one 3 positions behind that

Emachines t3830 I need the schematic for MB I umployed the wire for the push bottom without looking at the way they were plug. Now I do not know the correct aligning of the push bottom wires.


If you look at the motherboard there is usually a diagram labeled "FRONT PANEL HDR" that will tell you which pins are for: HDD LED, PWR LED, RESET, PWR ON. etc.
The chart / diagram may be a few inches away from front panel header.
the following example is from my emachine T2893 that I had opened because it won't power up.

the motherboard at the header connector labels pin #2 and with that you can figure out the other
pin numbers

example of diagram on motherboard (Confirm the pin numbers on your motherboard)


J9G1 PINS
| HD LED | 1 - 3 |
| PWR LED | 2 - 4 |
| RESET | 5 - 7 |

| PWR ON | 6 - 8 |

Hope this helps you figure which pins to hook you switch up to.

New motherboard


You don't say what case you are using. If it is proprietary and the front panel header is all in one connector, you can carefully back the connector pins out of the block using precision screwdrivers. I keep a bunch of two pin connectors from junked machines so I can create individual connector sets when changing motherboards (eg, PWR SW, PWR LED, HDD LED and RESET). This also requires that you know the pinouts of both the old board and the new one so you can get everything connected properly.

Very doubtful you will ever find an adapter to change from one front panel block to another.

The 9-pin connector probably uses a spacer pin between the legs of the PWR LED, while it seems the 6-pin does not have RESET.
