The On/Off switch is referred to as an ATX Power On switch.
Thought I would post that so it would make the switch simpler to search for.
This is one example of an ATX power on switch that I have found fits Many computers,
http://www.directron.com/atxswitch.htmlThe plastic button you push is the Power On Button assembly.
This plastic part can be heated with a hair dryer to soften the plastic, and easier removal of the defective Power On switch inside it.
{Hair dryer nozzle moved slowly back and forth on the Power On button assembly)
Usually there are two to three plastic tangs that protrude from the plastic housing, of the Power On button assembly.
These tangs are what hold the Power On switch in place.
After constant repeated heat from the inside of the computer, and due to age, the plastic becomes brittle. Breaks easily.
Heating the plastic should help prevent breakage.
Since the old Power On switch is going to hit the trash can anyway, you can also lower the entire assembly down in a bowl of fairly hot water. This to will help soften the plastic if a hair dryer is not available.
The new Power On switch has wires coming from it which connect to pins on the motherboard.
The plastic front of the computer is the Front Panel.
The area of pins on the motherboard, that the wires from the Front Panel connect to, is the Front Panel header.
The eMachines W3107 desktop computer uses an FIC K8MC51G motherboard.

After you click on the above file name, you may be staring at a white blank page for up to 30 seconds.
After the first page comes up it may take additional time to fully download the file.

Page 20 has the Front Panel Connector (Header) pinout.
Orient the board visually so we are both looking at it in the same orientation.
Processor to the Top, Ram Memory slots to the Right.
The Front Panel Connector is to the bottom right corner, BUT not in the corner itself.
It is the second connector of pins, over from the Right outside edge of the motherboard.
Two rows of pins.
5 across the Top, 4 across the Bottom.
The Pins across the Top are numbered Odd.
Starting from the Right side of the motherboard going towards the Left,
Pins 1, 3, 5, 7, and 9
The Pins across the Bottom are numbered Even.
Starting from the Right side of the motherboard going towards the Left,
Pins 2, 4, 6, and 8. There is NO Pin 10. Just a blank spot.
A) Pins 1 and 3 are for the Harddrive Activity LED light. (HDD LED)
B) Pins 5 and 7 are for a Reset switch, IF used.
C) Pin 9 is Not Connected. {Not used}
D) Pins 2 and 4 are for the Power On LED light.
If a Dual Color LED is used it connects to the header to the Right of the Front Panel Connector.
The one in the very bottom Right corner of the motherboard. {3 Pins}
E) Pins 6 and 8 are for the Power On switch.
