Where can i place in my motherboard power & reset jumper, i need diagram of my motherboard

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,

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.
