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.
