My emachine also won't turn on...

from the video the only think i can think of is that some computers have a little red switch that changes from an american standard voltage to european standard make sure that switch is turned to 120v(located in the back of the computer with mouse and keyboard connectors). secondly the other solution if that didn't work the power supply were the plug is connected into for the computer is propably not connected to the motherboard. to do that their is a connector on the power supply that should say P1 that connects to the motherboard. if all that fails have some own or yourself plug something in to the outlet in which you use for your computer to see if the outlet is at fault. If all else fails get a new power supply and have yourself or a computer technician or have a pro technician in PC maintence look at your computer or just buy a new computer.
*hope this was of use to you and sorry for the spelling mistakes*

Check the power lead and the mains outlet.
If these are OK and when you press the power switch on the computer and the power LED does not light up then most likely the switch mode power supply is faulty.
Switch mode power supplies contains dangerous mains voltage and I do not recommend a DIY repair. Just purchase a new switch mode power supply, make sure the wattage of the power supply is equal or greater than the old power supply.

Hi Nicki,
Sorry, this really sounds bad, it would seem that the hard drive is shot from your description. The data may or may not be recoverable. If you get a new drive, you will have to partition it first, then set it as your Master drive, then set the old one as a slave, install your operating system onto the master drive and try to recover the information on the old drive after you have that done. If you cannot successfully recover the information that way, you most likely won't be able to get it at all unless you backed it up onto a flash or cds or dvds.
Sorry for the news but that is what it sounds like

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.

A) When you hold a Power On button, (Switch actually), in for a count of 10 seconds, it turns the computer off.

(There is a Power On switch, located behind the plastic Power On button. Usually, the Power On switch snaps into the housing of the plastic Power On button.

Example of a typical ATX Power On switch,

http://www.directron.com/atxswitch.html

The Power On switch turns the Power Supply on.

Old computers had a metal rod, that when the Power On button was depressed, the button pushed against the metal rod, which in turn pressed against a power switch located inside the Power Supply.

The design after that, was a power switch located in the Front Panel. (Plastic front of the computer) A large cable, (Wire) ran from the switch to the Power Supply.

Now there is the Soft Power On feature. (PS_ON)

The Power On switch is a small Momentary Contact Switch. Pressing it closes a circuit. The Soft Power On circuit.

When a power supply is plugged into power, there is a constant 5 Volts (DC) present.
This is the 5 Volt Standby.

Closing the Soft Power On circuit, redirects the 5 Volt Standby power to a circuit within the Power Supply.
This in turn 'excites' the Power Supply, and turns the Power Supply on.

Sorry to be windy, but I wanted you to know how the Soft Power On feature works )

eMachines are a budget computer. As such they save the consumer money.
However in order to do this, the manufacturer will install low quality parts, in some areas of the computer.

One such part is the Power Supply.

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.
(Had you stated the Model Number I could have told you)

Enough power to spin fans, but not enough to spin fans, AND turn the Processor on.

Do you have access to another computer that is unused, but has a Known to be good, Compatible power supply?
It could be used for a test unit.

Tell me the Series, and Model Number of your eMachines, and I'll tell you what Wattage it should have, and what power cables, for the Power Supply.

(Some examples of Series, and Model Numbers, T1090, E4264, W2925, and so on. The T, E, and W are a few examples of the Series letter.
The numbers following the Series letter, is the Model Number)

If you wish I can direct you in removing the Power Supply, and installing the test unit. (And/Or a new Power Supply)

hI,

Plesae try to refix the RAM and it should work.

The problem could be many thing. Does it beep ? Can you see a white blinker on the upper left corner of the screen ? If you answer no for both questions, it coulb be the internal memory (ram) that is defect or even just dusty. But many other things could cause that. you can go to the link below and chat with a eMachine technicien.By the way when you try to turn off the computer, hold the power button until the computer shuts down.

Sounds like the power supply is faulty. Power supplies are very dangerous to try and repair, even for qualified technicians. I would also suggest not trying to plug it in or turn it on until the new power supply is in place. Faulty power supplies have been known to cause motherboards to permanently malfunction. Note: researching your issue, I came across several forum posts with complaints about emachines and their power supplies. The best way to solve this problem is to purchase a new power supply. If shopping online, www.tigerdirect.com and www.newegg.com are two places that specialize in PC hardware. A 400-watt power supply would probably more than do the trick for you. The cheapest one I found was $18.00. Make sure the power supply is compatible with your motherboard before you buy.

I hope that you took it back to them.
Have them check the power supply, too. Besides, a bad power switch and connections that would be the only thing that would be keep it from starting.

try to unplug again then plug in switch-o the power if it won't work then your power supply is busted you need to replace the power supply. if you want to make sure dismantle the power supply that connects to the motherboard, the connector has 20pins, then plug the power supply connect pin green and pin grey if the fan will rotate then the power supply is still okay.. if your power supply is ok check your outlet voltage if there is power including the circuit breaker that supplies power from this outlet.
