My Computer Doesn't Turns on when i press power button, the only thing that starts are the fans and thats it, no Power light or stuff like that.

U need technician, tell him to check with the other power supply then if he dont have another power supply then connect the Green and Blank point on the cable coming from the SMPS, if SMPS fan is powering on then issue is with ur motherboard and if not then issue is with ur power supply that is SMPS

Try to check if battery is removable. Remove all power source (battery and charger). Press power button for 10-20 seconds. Plug in with charger. Power on.

steve it can be many things.3-4 but you don't give enough information

Doesn't Turn On? Shows No Boot? Your question is not clear at all? If you are getting No lights when you plug in the Power Cord and No Lights, No Fan Running, No Hard Drive Running when you press the Power Button, then either your Power Cord is Bad or your Motherboard is bad.

If You see Lights when you Press the Power Button but you see nothing on the screen then your problem might be the infamous NVidia Video Graphics Card problem which is a known manufacturing defect on your computer's model. To get around it you will have to take your computer to a repair shop and have the Nvidia Video Graphics Card reflowed. This requires disassembling your laptop completely.

Hi,

Computer turns on but no display. This issue is commonly caused by electrical static on the motherboard. Try doing a power drain.

If this computer is a laptop:
1. Turn the computer off by pressing the power button for a bout 5seconds.
2. Take the battery out of the computer.
3. Unplugged the ac adapter.
4. Press and hold the power button for about 30 seconds. (without any power source)
5. Put the battery back in and plug the ac adapter back into the computer.
6. Turn the computer back on.

If this computer is a desktop:
1. Turn the computer off by pressing the power button for a bout 5seconds.
2. Unplug the power cable from the computer.
3. Press and hold the power button for about 30 seconds. (without any power source)
4. Plug the power cable back into the computer.
5. Turn the computer back on.

Thank you for choosing FixYa! have a good one!

This could have a bad power supply (in this case I would try a new one just in case).
All other things being normal, I would guess a bad motherboard.
The best thing to do is disconnect everything but the CPU and memory and try to start it.
If it starts, then start connecting stuff until it doesn't start--this will tell you what is bad.

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)

Does the power supply fan spin when you switch it on ??

Do you hear a"posting" beep??

Does the CPU fan start to spin??

If no to all of these probably dud mobo.

there is power buttom on the keyboard makes it wake up. try it

I’m happy to help further over the phone at https://www.6ya.com/expert/mustafa_06f84c65ab5cc745

Just for the heck of it, try blowing out the cooling fan with some compressed air. If you have never cleaned it and the fan stops turning, the computer will go into a safe mode and not start up.
Ther should be a vent somewhere on the side of the laptop that vents hot air cooling the CPU. That is where you need to blow it out.
Hope it helps- just a longshot...
