The power supply comes with a fan. Therefore I guess you need to replace a bad fan. Remove the power-supply case.

Note which direction the fan spins. There is an arrow on the plastic fan case. You will note that one side of the fan is open. Be sure to put the new fan so it faces the exactly the same way. Remove the screws holding the bad fan and cut the wires leaving enough room on them to solder on to the new fan.

Your replacement is usually a normal 80mm, 12 volt case fan that provides ventilation in most PC cases.

Connect the two wires to the new fan by soldering the red wire to the red wire and black to black. Use shrink tubing or tape to insulate the connections.

A second option is to replace the entire power supply with a new one (containing a new fan). Then there is no soldering involved. If you look carefully enough, you will find them cheaply on line.

Hope this helps. :)

I hear two beeps when i conect power suply on my emachine t5212 model


Very sorry about your son.

If you can't find the real problem, you can always put that hard drive into another PC to get the files. If so, be sure to looking to a potential "jumper" setting on that drive for it to be recognized.

Emachines e4026 non-responsive


I don't think it's an overheating CPU. It would stay on for a bit longer if it was that. My best guess is a power supply issue. Either your power supply is bad, or more likely something is pulling too much power from it. Emachines are notorious for using the bare minimum hardware... possibly the extra hard drive is pulling more juice than the power supply can handle, so it shuts down. Try disconnecting power to the new hard drive and see if the machine comes up. If it does, you need a new, higher wattage power supply.

Have a e machine fan runs but connect monitor to another computer it works. smell a burning smell when turn on pc. Got it to come up once by unplug power hold on button 45 seconds plug in and turn on came...


The smell is the Power Supply.

Typical example of a Power Supply not installed in a desktop computer,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4435072&CatId=106

[ NOTE*
This is not an example of a direct replacement Power Supply for your computer. I would need to know the Model Number of your eMachines to give exact information ]

Bad Power Supply. Weak voltage power rail. (Or rails. There are three main voltage power rails for a Power Supply used in an eMachines desktop computer)

Enough power to light LED lights, and apparently spin fans, but Not enough to turn the Processor on.

Watts = Voltage times Amperage.
One measurement used for measuring the maximum available power output, of a desktop Power Supply, (SMPS. Switched-Mode Power Supply), is to state the Maximum Wattage available.

Typical maximum Wattage available for a typical eMachines Power Supply, usually averages from 150 to 300Watts.

1) ALL of the LED lights on at one time, will use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.
Depends on what Processor it is.

(Note* Intel Pentium II processors use less than 51 Watts)

Solution is to replace the Power Supply.
This isn't as hard as it 'sounds', if you have never performed this procedure before.
I know you can do it.

If you need guidance in replacing the Power Supply in a step by step for your eMachines, please post in a Comment. (Believe upper right of your page)

Should you also desire recommendations to compare for a Power Supply, I would be happy to provide them.

Emachine total black , this are on fan


LED lights are on? Fans spin? I suggest you have a bad Power Supply.

1) eMachines are noted to have low quality Power Supply's.
Saves eMachines money so they can sell budget computers.

2) A bad Power Supply is one of the leading causes of computer failure. I have, (Had actually), a shop half full of computers with this 'ailment'.

Some caused by the owners never cleaned out the inside of their computer, nor the inside of the Power Supply, with a can of compressed air for computers on a regular basis as needed.

3 to 5 years without cleaning the inside of their computer.
Mice could have made nests inside easily, with the 'Gunk' that was there. A bald eagle could have too. Rant off.

Others, caused by the computer manufacturer used a low quality Power Supply.
Low quality components used inside.
One of the major components that fails, is caused by a particular Electrolytic Capacitor that is used.

http://en.wikipedia.org/wiki/Capacitor_plague

3) Power Supply's used in PC's are a type of SMPS.
(Personal Computer. Statement holds true no matter what type of personal computer it is)

[ SMPS = Switched-Mode Power Supply
PSU = Power Supply Unit
All terms relate to a Power Supply used in a PC ]

A bad Power Supply will have a weak voltage power rail.
There are three major power rails used in the ATX form factor Power Supply, for an eMachines T6420 desktop computer.

A) The 3.3 Volt power rail (DC)
B) The 5 Volt power rail (DC)
C) The 12 Volt power rail (DC)

(Two D cell flashlight batteries produce 3 Volts DC)

A Power Supply with a weak voltage power rail, may have enough power to light LED lights, and spin fans, (or spin a few times, ans stop), but won't have enough power to turn the Processor on.

1) ALL the LED lights combined use less than 1 Watt of power

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts.
Depends on what Processor it is.

eMachines T6420?
Uses an AMD Athlon 64 3400+, processor.
(Socket 939)

[The motherboard used is an MSI ms-7207
Also known as K8NGM2-L ]

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T6420

This Processor can use Up To 89 Watts.

http://en.wikipedia.org/wiki/List_of_amd_athlon_64_processors#.22Newcastle.22_.28CG.2C_130_nm.29

No Processor running, No computer.
No computer = No Video Signal

Suggest using a KNOWN to be Good, Compatible power supply, for a test unit, if available.

Should be the ATX form factor.

Approximately 6 inches Long, (15.24cm), 6 inches Wide, (15.24cm), and 3-1/2 inches Tall. (8.89cm)

250 Watts.
Correct amount of power cables, and the correct type.

Emachine 5210


Emachines used to use a poor quality power supply made by Bestec, I believe the quality is supposed to have improved in the last few years but inconsidering the number of dead Emachines that wind up in my workshop I doubt it.
The problem you have is that being a poor quality power supply there is a very high risk that it damaged the motherboard when it went out.
If you can borrow a power supply just to test with all the beter BUT be carefull some Emachines are proprietary and the main motherboard plug is not always wired in the standard way.
Check here for a replacement power supply if you can prove your motherboard to be OK.

Have a look on this site for examples of standard and proprietary power supply wiring colours.

Since your computer is working but no display at all. Hope this steps would be helpful in your problem.


1. Turn on your computer, If the problem works again and no display.

2.Turn off your computer by pressing long your power botton until the fan stops properly.

3. Unplug you computer 220volts power chord at the back of your computer.

4. Reconnect again the 220volts power chord after 1 minute.
