E-machine t2893 need to know what pins I connect front power cable too

For any desktop computer using Windows:

The main power cable coming from the Power Supply, is an ATX main power cable.

It is the power cable with the longest connector.
It will either be a 20-pin, or a 24-pin connector.

IF, this is directly towards an eMachine T2893 Desktop PC, it uses an Intel D845GVSR motherboard.

Also note that eMachines Support > Specifications, states the T2893 uses an Intel 845GV motherboard chipset,
( Chipset ),

The plastic front of your desktop computer is the Front Panel.

The rectangular area of pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header. (Sometimes abbreviated FP1 on the motherboard )

Looking at your motherboard as it's installed in the computer case, the Processor is to the Top, Ram Memory to the Right, and the long white PCI slots to the Bottom.

The Front Panel header is on the Bottom of the motherboard, under the CMOS round battery.

There are two rows of pins.
4 across the top, and 5 across the bottom.
{ Top row 4 pins, space
Bottom row 5 pins }

The Top row of pins are numbered Even.
The Bottom row of pins are numbered Odd.

Starting from the Left side of the header going to the right, on the Top row;
{ Left side of the motherboard going towards the right side of the motherboard }

Pins 2, 4, 6, and 8. There is No pin 10.

Starting from the Left side of the header going to the right, on the Bottom row;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED light.
Pin 1 is for the Positive ( + ) wire.
If the harddrive LED light 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) Pin 9 is for 5 Volt (DC) power. Not used.

D) Pins 2 and 4 are for the Power On LED light.

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

To the right, and up, is the BIOS Configuration Jumper Block.
3 pins.
Pin 1 is towards the CMOS battery.

Normal default is the jumper is on Pins 1 and 2.
To configure it is placed on Pins 2 and 3, BUT in a proper method.

Now click on - D845GVSR Product Documentation & Manuals, (In blue), to the left of Download.

This is a PDF file.
The computer you are using has Adobe Reader on it, which uses PDF files.

After you click on the link it takes a few seconds to see the first page.
It takes additional time for the file to fully download.
Suggest you let the file download all the way, before looking through it.
(Watch the download progress bar)

Don't know if you are familiar with PDF files. If so, please disregard the following:

At the top of the PDF file in the header, is a page number box.
The page number box is to the Left of the blue Down Arrow.

Put your mouse cursor in the page number box. Left-click once.
Type 11.
Press the Enter key.
This method takes you immediately to Page 11.

Page 11 shows you a crude illustration of your motherboard.

The orientation of how the motherboard is sitting in this illustration, will be different than how your motherboard is sitting in your computer.

In your computer, the Processor will be to the Top, and the Ram Memory slots to the Right.
The Front Panel header is to the Bottom Right corner, of the motherboard. ( S )

(Front Panel header = Front Panel connector)

Go to Page 31.

In the illustration, the Front Panel header is designated by the letter
C.
J9G1 is the Front Panel header.
(Junction 9G1)

Here you will see the Pins numbered.
Starting on the Right side, going Down from the Top,
Pins 2, 4, 6, and 8.

Starting on the Left side, going Down from the Top,
Pins 1, 3, 5, 7, and 9.

Looking at the Front Panel header (J9G1) on the motherboard, as it is sitting in your computer;

There are two rows of Pins.
4 across the Top,
5 across the Bottom.

Pin numbering on the Top row of pins, starting from the Left, going towards the Right,
2, 4, 6, and 8.

May take up to 30 seconds, before you see the first page.
(You will be staring at a blank screen until the first page comes up. The file is downloading in the background)

Took 5 seconds before I saw the first page, and an additional 12 to fully download, using a medium speed DSL connection.

The Front Panel header on the mobo is shown on Page 31. (C on the illustration. J9G1 on the mobo)

The Front Panel connections are on Page 32.

Barring that you cannot download this PDF file, or do not understand the manual, I will detail the Front Panel header connections.

Orienting the motherboard so we are both looking at it the same way;

The Processor is at the top, the ram memory slots are to the right side of the mobo, and the white PCI slots are to the bottom.

There are three PCI slots. The one closest to the Processor is PCI 1.
The one closest to the edge of the mobo is PCI 3.

To the far right of PCI 3 is the Front Panel header.
It's the header located closest to the Right side of the mobo, and the bottom edge, and is directly below the
CMOS battery.

There are two rows of pins.
Four across the top, Five across the bottom.

The top row of pins are numbered Evenly.
The bottom row of pins are numbered Odd.

Starting from the Left side of the mobo, going to the right, on the Top row,

Pins 2, 4, 6, and 8. (There is No 10)

Starting from the Left side of the mobo, going to the right, on the Bottom row,

Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the Harddrive Activity LED
If you have a wire with a + sign on it (Positive) it goes to Pin 1.

B) Pins 2 and 4 are for the Power On LED.
(Pin 2 to the Green LED lamp, Pin 4 to the Yellow LED lamp, if applicable with your computer)

C) Pins 5 and 7 are for a Reset switch. (If applicable)

Hi,
On the motherboard the pinouts on the front panel should be colour coded, and marked with letters like in this picture >>>>>


The connectors are also marked corresponding to where the connect on the motherboard, like in this picture >>>>>>


If the board is not colour coded then the motherboard will marked with the same letters, you may need a strong light to see the marks.

Regards.

E-Machines are notorious.....I had the same trouble with my T3624, replaced the MB and alls' well. The green light just shows the power is connected.

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.

Since you are looking inside, try this. Trace the wires that come from the power switch back to the Motherboard. The wires from the switch will connect to two pins on the motherboard. Carefully jump those two pins with a screwdriver and the machine should turn on. I would suggest doing this with all drives and cards unplugged first.

As long as the rating is the same as the power supply you should have no problems
Make sure to check your wiring and all the connections are correct or you could have one expensive paper weight.
