Question about E-Machines (308714) Motherboard

2 Answers

T3624 MB someone pulled off the 3 wire pairs to the front bezel. What's the pin out for the 2 leds & power on??

I bought a 'dead' T3624 Emachine at a yard sale. When I opened it the surprise was that the 3 wire pairs to the front bezel & the power cables to the HD & CD had all been pulled off. There's no documentation or indication on the Intel MB as to the pin out for connecting the wire pairs that are labelled PWR LED, HDD LED, & PWR S/W to the 9 pin connector at the lower front on the MB. Anyone know the pin-out or where to find it.
Thanks,

    Someone mentioned that the pin out was printed over the board battery & sure enough it was so that solved one clitch. However when I tried to power up, still dead & then I read the threads about the PSUs in Emachines being so-so or worse. Looks like this one failed AND took out the MB as well because I tested the PC by trying another known to be good PSU. So now I'm cruising EBay looking for appropriate parts & pieces. By the way folks thanks for your help, this is a great forum.

According to the internet, your computer has an Intel 845GV chipset motherboard. Intel tends to use a generic pattern for connecting the front panel connectors. A description can be found on intel's site.
If this doesn't solve your problem, comment back with the motherboard model number. Look on the board, it should be printed somewhere, and it should start with D845GV...something something...

Starting on the LEFT side going towards the Right, BOTTOM row;
Pins 1, 3, 5, 7, 9, 11, and 13.

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.

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

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

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

5) The rest of the pins are N/C. Not Connected.

Don't forget to plug the 4-pin ATX +12 Volt power cable in,

Manual for 41t-ad motherboard


http://www.skyline-eng.com/index.cfm?fuseaction=product.display&Product_ID=8665

Bottom/Right corner of motherboard - Front Panel header. Take an LED with two wires on it, and touch pairs of pins. ( 2 )
When you briefly touch the 2 pins that turn it on, you have the Power On switch wires.

Do not touch these pins again, and test the rest of the pins.
LED stays on? You have the Power ON LED pins.
LED blinks? You have the HarDDrive activity LED.
Computer restarts? Restart switch pins.
Some pins do nothing, 4 in a row may be for speaker, some pins have +5 volts, and are not used either. (Factory use)

This is not a photo of your motherboard. Please use it as a general guide on what to look for on your motherboard. Most brand name systems will have the connector pins placef on the edge of the motherboard that is closest to where the wires coming from the power button are being routed. Pay attention to a set of pins that equal the amount of connection wires you have. When you see it, look around the pins and you will see etchings that describe which wire goes on what pin.
NOTE: Please remove the AC cord from the computer and that all keyboard, mouse, video, network cable and usb slots are disconnected and empty. Do not power the pc until you are certain you have matched the connectors to the right pins.

How to hook up the face plate of a emachine w3400 Wich includes 3 wires 1 power butten and 2 led lights


Look at the pinout of the Front Panel header, of the eMachine W3400's motherboard.

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

The motherboard for an eMachines W3400 desktop computer is an MSI ms-7145
(Micro Star International)

Orient the motherboard in your view so that we are both looking at it the same way.
Processor to the Top, Ram Memory slots to the Right, white PCI slots (3) to the Bottom.

JFP1 is the Front Panel header.
(Junction Front Panel 1)

JFP1 is on the Bottom Right corner. There are two columns of pins arranged vertically.
(The JFP1 header runs parallel to the Right side of the motherboard)

The Left side column of the JFP1 header is numbered Odd.
Starting at the Top and going Down, the pins are numbered;
1, 3, 5, 7, and 9

The Right side column is numbered Even.
Starting at the Top and going Down, the pins are numbered:
2, 4, 6, and 8.
There is NO Pin 10

A) Pins 1 and 3 are for the HarDDrive Activity LED light. (HDD)
If the LED light is dim will operating switch the wires around

B) Pins 5 and 7 are for the Reset switch. (Reset button)
> IF Used

C) Pin 9 is Not used. (NC. No Connection)

D) Pins 2 and 4 are for the Power On LED light (If dim switch the wires around)

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

Trace the wires back to the Power On switch. Even if it means temporarily removing part of the Front Panel to see.

Same with the LED lights.
See which wires go to the Power On LED, and HDD Activity LED. (Harddrive Activity LED)

Follow the 3 wires, and tell me where they go to on the Front Panel.
USB port?
Memory Card Reader?
Firewire port? (a1394)

T6410 EMACHINE TRYING TO CONNECT START BUTTON


The motherboard in your computer is an MSI MS-7145, which is also called RS480M. You can download a copy of the manual here. The front panel connections are on page 2-20.

Looking at the header JFP1, pins 1 through 9 (odd numbers) are the front row, pins 2 through 10 are the back. Pin 10 is the missing pin. The power switch connects to pins 6 and 8. The power LED connects to pins 2 and 4. The HDD LED connects to pins 1 and 3. The reset button, if used, connects to pins 5 and 7.

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.
