I am a single dad with very limited funds and my daughter was hoping to get a computer for Christmas, anyway I scrounge as a hobby (and find all kinds of stuff) I found this computer and monitor and thought perfect I've got the present she's wanting but when I went to plug in the computer I got nothing the monitor works great so I took the side off the computer and it looks like it. It appears to just be disconnected in spots from the previous owner. I pride myself and fixing stuff but this has got me stumped so I'm reaching out to computer experts in a desperate attempt to try to fix it myself because I cannot afford to have it fixed. The name of the computer is model: emachines T2984 and the S/NO: XAT4920012284. I took some pictures of the wires that are disconnected inside of it. I do know it's getting power because I tested it with my meter and I could see lights lighting up on the inside but I noticed three wires that come off the power button in the front seem to be disconnected and I can't for the life of me find out where they go connected to. It doesn't appear like anything has been removed from the computer just some wires disconnected. Please guys I'm begging you can you please help me with this and tell me where they go connected or maybe why it won't turn on. I just got a good feeling this computer is alright its just been disconnected. Please please please guys help me with this! Oh the three wires that seem to be disconnected are H.D.D. LED, POWER SW, POWER LED.

Those wires would typically go onto pins on the motherboard. Are you sure that the computer has a hard drive, CPU and Ram still installed?

Maybe the attached picture will help, I think its the right motherboard.

When you'd open the side of your case and look at your motherboard, in the bottom right  of the motherboard there should be a a section with 5 rows of pins. According to a picture on google from another forum somewhere, here is the diagram to wire it
 
When plugging in the wires, make sure the little smooth side with the label (ex: HDD, Power SW)  is facing outwards while the side with the visible metal rectangle is pointed inwards.
 
I hope this helps

Dear golden1980,

     You have to connect POWER SW. to pins 6 and 8 as the other

fellows have suggested b/c w/o this hooked up. you will never get

your board to turn on!  Older computers had what amounted to a

light switch on the front of the computer case which turned on the

power supply and fed current directly to the motherboard.  The

engineers went to a more complicated scheme to allow for things like

allowing the computer to stand by, sleep, and hibernate.  They, (the

engineers) must have been clued in by M-Soft and others to make such

a change.  There are other reasons too, but they are beyond my

scope.  You could short pins 6 and 8, but I would counsel against

that as you could ruin your project in less than a second. 

    Polarity does not matter b/c it is just a switch.  I have an

eMachine board with the same pinout as what the others suggest and

you can download the manual if you can ascertain the model no. of

the board which is usually printed in white somewhere in the middle

of the board, especially, if it has PCI slots.  It looks as if you

have an ASUS board similar to mine as the pinout as described if

correct is the same.

     Polarity does not matter for this switch because it is only a

switch.  HOWEVER, for H.D.D. LED and POWER LED this is important b/c

they will not light up!  No harm should come to your board shod you

get these last two wrong, it will funtion, bit w/o these lights.  I

found that in my case (the enclosure,) the two wires had a white

wire and a color wire.  The color wire(s) go downward if the tower

is up as the pinout is "up" or they go to the left if you have the machine

with the board facing up.  The color wires are the (+) on polarized things

like lights and most other things.  This is why you will find on most cases

except some that are mass produced, many colors of wires on plugs with

only a few wires to connect.  Usually 4 or 5 or less as most of what you are

dealing with are two pin connectors.  Hopes this helps if you have not

already had success!

 

 

                   Sincerely,

 

                   BLLEsq
