The eMachines C2685 uses an FIC VC37GV motherboard. (First International Computer, Inc.)

Here is the motherboard manual,

After you click on the above link, give it up to 30 seconds to download. This is a PDF file.

Barring you cannot download the file, I will state the connections for the Front Panel header on the motherboard.
(Plus state the page to reference to, in case you can download)

View the first link, with the photo of the FIC VC37GV motherboard.

As shown, Processor is at the top, Ram Memory slots are to the right.

The Front Panel header is located at the very bottom right corner.

It is parallel to the outside edge of the motherboard. There are two rows of pins.
(Page 12)

The Front Panel header has 5 pins going across the top, and 4 pins across the bottom.

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

On the Top row starting on the Right side, going towards the left, the pins are numbered 1, 3, 5, 7, and 9.

On the Bottom row starting on the Right side, going towards the left, the pins are numbered 2, 4, 6, and 8.

A) Pins 1 and 3 are for the HDD LED. (HarDDrive activity LED)

B) Pins 5 and 7 are for the Reset switch

C) Pins 2 and 4 are for a Dual Color Power On LED, if used.
Green goes to Pin 2. Yellow goes to Pin 4.

Otherwise Pin 2 is Positive, ( + ), and Pin 4 is Negative. ( - )

D) Pins 6 and 8 are for the Power On switch.
(PWR1, or SW1)

There is a small 3 pin header, just above the Front Panel header. (Page 12)

This is for a Power LED that has either two wires, or three wires.
The pins are numbered from Right to left.

Pin 1 is for the Power LED, and Pin 2 is for Ground, if using a two wire Power LED. (Not dual color)

Pin 1 is for the Power LED, and Pins 2 and 3 are for Ground (GND), if using a three wire Power LED.
(Page 13)

I have emachine t seris t2862 desktop and I donnot know how to connect power swich in mother board please help me

On the motherboard there will be a small set of connectors marked FPANEL, next to each of these will be a set of letters (usually PW, RES, HDD, MSG) and an earth pin, From the power switch you will see a two wire set normally black and white ending in a connector, this connects to the PW pins on the FPANEL

I have the emachines model W3107 and am having problems turning it on and off. I have called emachines to order the part but they will not assist me because my computer is out of warranty. They do not even...

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,

The 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.
(First International Computer)

This is the download page for the motherboard manual, for the FIC K8MC51G motherboard,

Click on the top file name >

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.
{Took 40 seconds to see the first page, and the file was fully downloaded.
Medium speed DSL connection}

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.

You can connect the power connector to the corresponding sockets. It wont make any problem if it is changed one another. Only thing you have to connect in the correct position.

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.

Hi there
The front panel connectors are mainly,
  • harddisk activity connector
  • power switch connector
  • reset switch connector
  • power LED connector
  • speakers connector
  • USB connector
Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.

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)

| 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.

EMachine no power

Ok for a start the power switch is not green and white that is the power led, you need to look for a red and black wire normally marked on the connector and motherboard as pwrsw or pswitch.
if you believe it to be the switch unplug the connector and jump the connection on the motherboard using the reset switch or a jumper, or not recommended but have done this myself many times using a flat blade screw driver very carefully and touch the 2 pins to complete the circuit.
if it doesnt power on then its more than likely it is the power supply but the motherboard being faulty could also cause this to happen.
the problem i have found with emachines is that its difficult to get replacement power supplys
