As for the Power Supply 99% sure it is an ATX which as long as you get the same Watt as the existing you will be okay. Make sure you look at your existing connectors to see if you have a 24 pin or 20pin motherboard and 4 pin or 8 pin additional power plug (black and yellow wires) and the new power supply has matching connectors....older ATX supplies have only 20 pins, but there are converters from 20 to 24 pin available.

Watch for the new power supplies and your drive connectors as some of the new power supplies have limited ATA plugs...if you have a lot of ATA devices you might need SATA power convertor plugs or ATA splitters to get all you ATA devices up.

Where will the restart and power cable will be connected in motherboard i5 Intel

Download the Technical Manaul of Motherboard from following link.

On page 12 of the manual you will find the diagram of your board. The power connector is located at position "N". Hard reset feature is not provided in this board as it was available in old mother boards. However System Recovery can be performed using BIOS Jumper located at position "P" on the motherboard. Remember that BIOS Configuration Jumper is used to for System Recovery not for Reset.

How to connect EPIA_M860-12E to a monitor for starting it?

1) Power Supply to Motherboard
2) Motherboard to Monitor

Motherboard has Processor, and Ram Memory on it.
Monitor cable plugs into I/O area on motherboard.
(Input/Output area. Where the Mouse/Keyboard/Audio ports, etc, are)

You can lay the motherboard on a piece of cardboard, then on the table you're working on.
Make SURE you are FOLLOWING Anti-Static Precautions. If you are not aware of what these precautions are, please post back in Comment.

To start the Power Supply, jump the two contact pins in the Front Panel header on the motherboard, with a small flat tipped screwdriver. (Jewelers screwdriver is the best for this)

(The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.
Main wires being;
Power On switch, Power On LED light, HarDDrive activity LED light, and Restart switch; IF your computer uses a Restart switch )

If that doesn't start the Power Supply, then use a jumper wire on the Green, Soft Power On wire, to ANY Black wire. ALL Black wires are Ground wires. (Negative connection)

The contact period is NO more than 2 seconds.

Bottom -> Users Manual UM_EPIA-M860_113.pdf

After you click on the above, a small window will come up on the right.
Make SURE there is a Green dot in the small circle to the left of -
Open with.
If not, click in the empty circle to the left of Open with.

[Should state Adobe Reader (default) in the box to right of Open with]

The Front Panel header is on Page 31 (Adobe Reader page number box at Top)

Two rows of contact pins.
TOP row is numbered EVEN.
BOTTOM row is numbered ODD.

Top row from Left to Right, is Pins 2, 4, 6, 8, 10, 12, 14, and 16.
Bottom row from Left to Right; is Pins 1, 3, 5, 7, 9, 11, 13, and 15.

Pins 6 and 8 are for the Power On switch.

{ Pins 2 and 4 are for the HarDDrive activity LED light.
Pins 10 and 12 are for a Reset switch, IF a Reset switch is used.
Pins 14 and 16 are N/C. Not Connected.
Pins 1 and 3 are for a Dual color Power On LED light.
Pin 5 is the Ground for the Dual Color Power On LED light.
Use pins 5 and 7 for a two wire Single color Power On LED light.
Pins 9 and 11 are N/C.
Pins 13 and 15 are for an internal speaker. The small speaker/buzzer for hearing BIOS Beep Codes ]

The main power cable is a 20-pin ATX main power cable.
General example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,

You want the main power cable plugged into the motherboard, as shown in the photo to the Right.
The Green wire is the Soft Power On wire.
-> ANY Black wire is a Ground wire.

The preferred jumper wire is a straightened out paperclip, bent into a U-shape.
The top of the U is wrapped a few times with black plastic electrical tape. This taped area is for your fingers, and thumb to hold onto.

Turn the U shape over, and it is the 'legs' of the U that you are going to use.

One leg goes down into the socket hole, where the wires go into thew connector; RIGHT NEXT TO the Green wire, and slides down in.
Slides past the green insulation of the wire, and Touches a metal terminal at the End of the wire. MUST touch that metal terminal.

The other leg goes down into a socket hole, with ANY Black wire in it.
The contact period is no more than 2 seconds.

Power Supply comes on you have a bad Power On switch.
Power Supply does NOT come on; you have a bad Power Supply.

The Soft Power On circuit is 5 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.
However, not stating that there may be a small spark, as you connect the U-shaped jumper wire.
For this reason you may wish to use a glove, on the jumper wire hand.

Cross-compile connections? I am at a loss.
Explain further in a Comment.

How do i configure this hard drive for a 'slave' ?


Ok, you ill be able to see the jumper configuration on the hard drive itself. Here is an example on what the jumper diagram will look like on a hard drive.

Now, all you need to do is to have a look on your hard dive and see where you need to place the jumper for the slave configuration. Here is what a jumper looks like.


After you have done this, you only need to plug the hard drive into your pc.

Hope this can be of help.

Kind regards

I have a HP Compaq Dc7600 sff. The computer made a popping noise and went dead. I waited a few minutes to see if it would restart. It did not restart. No power at all.

Have you checked the power supply unit of the equipment?
Is it working?
If yes, the next step would be to confirm whether the memory is healthy.
If both the memory and the power supply are working, then the problem may not be too serious, otherwise, you will need to replace and go deeper and check the status of the motherboard and the processor unit.

*Note: All drives should remain disconnected during the testing process

Emachine T3828 power switch connection to motherboard

The "Ultra Helpful Instructions" that Emachines provide (here: state that when replacing the system board, "18. Attach all cables to new system board", but fails to say where that would be for each cable.

The site below says it's a genuine Intel board in there, so, congrats on that.

And with that, the link to the manual:

You're looking for the info on page 32, I believe.

See if that fixes it up. If not, post back.

Wants to get more explanations.

different motherboards and hard drives use different settings for each application unless U work on identical machines with identical parts. MAXTOR,SEAGATE ( old er 1's ) QUANTUM,CAVALIER,IBM deskstar, etc use different jumper settings depending on the application.. EXAMPLE older maxtor hard drtives set JUMPER 50 to run as a master with no slave present jumper 50 is the jumper closest to the ide cable ..
