Emachine desktop power switch is shot

My d-Machine desktop will not power up. The power supply seems to be working because there are lights within, but the external power button on the front of the cpu does not work. Nothing happens when you depress it.

Emachine troubleshooting


This is typically caused by a power supply failure. Failing power supplies can have enough power to turn on lights and fans but not enough to start the computer. The power supply does not store any data so replacing it is a low risk and low cost effort. It is a very well documented process so search the Internet for "replace power supply" for more details. I hope this helps. Good luck!

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.

I have an eMachines ET1810-01 PC Desktop. After a power outage, the computer won't turn on. When I press the power button to turn on, I see it supplied for about 5-6 seconds and off it goes. During this...


same thing happened to me with this machine -- actually, two power outages. I thought I was protected, as I run UPS and the machine should have hibernated (I know it did the first time). At any rate, after the first failure, the clock wouldn't run right, and after the second, the exact thing you describe happened.
I was within days of losing the warranty, and sent the box back. Cost $27 to ship, insured. They replaced motherboard and reformatted hard drive. It works fine now. 90-day warranty on the repair.
In short, your motherboard is toast.

Emachine 3240 possible power problem?


I would suggest try to swap the power supply out with another known good power supply.

I've seen where even though the light on the motherboard is lit, it is not getting enough power to start the machine up, especially if you have a higher end video card connected to it.

EMachines not powering up


You may have updated windows to a point that this old machine cant handle the revamp. Kick back to an older ops system, although that poses security risks. Your motherboard may also have given up. Best advice - upgrade, and retire this machine to the recycle bin.

E-machine 5220 power up


Emachines have notoriously cheap power supplies. Often, while the power supply itself doesn't fail, it causes the failure of motherboard components, essentially trashing the computer.

Try the following:

First check and make absolutely certain that the power switch connector is properly connected to the motherboard. (Take standard grounding/safety precautions: wear a properly-grounded grounding strap, for example, when working with any internal components.)

Obtain a known-good power supply of equal or greater capacity to your eMachines PS and switch 'em out. 

If either of these fixes your problem, well and good. If not, the problem may be, as is all too common with eMachines power issues, a motherboard issue caused by the power supply.
