Question about E-Machines eMachines Desktop PC

My emachine also won't turn on...

During recent sorm, our computer quit-won't power up. I checked the switch and took the power supply to a repair shop to have it tested. It is oK. I suspect that now I need a new motherboard. I am capable of replacing it myself , and not yet willing to spring for a whole new system, problem is, I don't know what kind of motherboard I need to buy. (preferably a non-emachine brand)
The system is a W31o7 desktop, 1.8Ghz , 1600MhzFSB, AMD Sempron Processor 3100+. What kinds of motherboards willwork with what I have?
Thank you in advance

    Dragonfire,

    i hadn't thought about it. Is there an easy way to determine if the problem is in the processor or the motherboard?

    thanks

Won't turn on


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

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.

When the computer on/off button is pressed , the CPU fan and tower exhaust fans start running, the blue light around the power button does not light and the boot up process goes no further. Fans continue...


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)

Possible reasons are bad power switch, bad power supply, bad motherboard, bad memory , device card is not seated properly. Suggest replace power cord to see if still no power, also you may want to remove cover and make sure all your memory and device cards are seated corrrectly. If you get a amber light at the power button, bad motherboard is likely cause

EMachine will not turn on.


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.

Puter wont turn on


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.

Could be a power Supply fail. It is well known in the trade that Emachine power supplies are very poor. A new power supply is easy to fit and cheap.
