Will not turn on when I hit the power button. but all the fans come on, No power to the disk player,floppy drive, replace the power supply but still the same problem. I buy passed the power switch but still the same problem Did have a power surge in the neighbor hood alot of my electronics got damaged do you think the mother board has been damaged?

Power Supply with a weak voltage power rail.

[There are 3 voltage power rails. 3.3 Volts, 5 Volts, and 12 Volts. All are DC Voltage ]

Enough power to light LED's, and spin fans, but not enough power to turn the Processor on.

1) If ALL of the LED lights were on at once they would 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.
Just depends on what Processor it is.

Suggest you check the three main voltages with a multimeter.
Since the Soft Power On circuit uses 5 Volts, I have a feeling the 5 Volt power rail may be the bad one.

An economical multimeter can be purchased for as little as $5 to $12.
Available in a multitude of stores. An auto parts store is but one example.
Need guidance in using it just post in a Comment.

Or you can borrow a KNOWN to be good, Compatible power supply, and use it for a test unit.

For additional questions please post in a Comment.

If your computer has the old floppy disk drive on it, then Remove the Power Cord, Remove the Case and then remove the cable from the back of the floppy disk drive. Evidently the drive is bad.

If there is no floppy disk drive on your computer, turn the computer off, restart it and watch the screen for which key it says to hit to get into the System Bios or System Setup and hit that key. You have to hit the key when you see the message or it will not work and you will have to reboot it. Once you get into the bios check your devices and drives for the Floppy drive and set it to None or Not available ( It is probably set on auto or enabled). Also check your Boot Sequence or Boot Order in the bios and remove the Floppy Disk from being in the boot sequence or set it to be after the Hard Drive and CD Drive.

There can be many things associated with no power to the computer.

• The outlet into which the computer is plugged may be inoperative.


• The surge protector you are using may be inoperative.


• The power cable may be loose or damaged.


• An internal device may be damaged.


• The power supply may be inoperative.

Basic Troubleshooting Power to the Computer
There may not be a consistent flow of power to the computer.

1. Verify that the outlet into which you are plugging the computer is operational.


2. If you have the computer plugged into a surge protector, plug it directly into the outlet.


3. Verify that the power cable is plugged securely into the back of the computer.


4. If you have a monitor with a removable power cord, swap the power cords between the monitor and the computer.

Note: If you recently added a new hardware device prior to experiencing the no power issue, turn off the computer and remove the newly added hardware. If there is still no power, reseat all the other cards and cables in the computer to verify that all other devices are seated securely.
Resolving Power Supply Issues

• External Device Conflicts
There may be an external device causing the computer not to turn on properly.


1. Before continuing, verify your computer is turned off.


2. After you have established that adequate electricity is going to your computer, verify that the voltage switch on the back of the power supply is set correctly. The small red switch is to be set to the 115-volt setting.


3. Remove all external devices except the monitor and turn on the computer. If the fan on the back of the computer now spins, turn off the computer. Plug in the external devices one at a time and turn on the computer after each device is added.

Note: If you removed all external components and the fan on the back of the computer does not spin, the problem is with something inside the computer.


• Internal Device Conflicts
This helps determine if the issue is a damaged or badly seated component.


1. Verify that the computer is turned off.


2. Remove the case from the computer.


3. Remove all the red, yellow, and black power connectors from each floppy disk drive, CD-ROM drive, and tape backup unit that is in the computer. The only devices connected to the power supply are your hard disk drive and motherboard.


4. Turn on the computer and verify that the fan on the back of the computer spins. If it does not spin, turn off the computer.


5. Remove the power connection from the hard disk drive and reconnect power to one floppy disk drive. Turn on the computer and verify that the fan on the back of the computer spins.


6. Reseat the power connection from the power supply to the motherboard. Turn on the computer and verify that the fan on the back of the computer spins. If the power has been restored, turn off the computer and reconnect the power connections to the devices. Test the computer for power after reconnecting each device.


• Power Switch
The power switch may not be functioning properly.


1. You may need to open the case and readjust the power switch.


2. Locate the control panel inside the computer and remove any screws holding it in place.


3. Turn on the computer with the control panel removed by pressing the button on the control panel that corresponds to the power button. If the power supply fan spins and/or the computer turns on, put the control panel back in its place. Try to turn on the computer again.


• Test Switch and Diagnostic LED
  
Note: Not all power supplies have a test switch and diagnostic LED.
Certain power supplies have a test switch and LED to help better troubleshoot the device. The green LED is always on when the computer is powered on. If the computer is not receiving power please perform the diagnostic test below.


1. Verify that the computer is turned off.
   
2. Remove the case from the computer.
   
3. Remove all of the red, yellow, and black power connectors from each floppy disk drive and ROM drive and the tape backup unit (TBU) that is in the computer. Remove all power connectors from the motherboard. The only device that needs to be connected to the power supply is the hard disk drive.
   
4. Press and hold the test switch for five seconds on the power supply, and then verify that the green light on the power supply comes on.
   
5. If the light comes on:
   
   1. The power supply is good and something that was plugged into the power supply is causing the computer to not turn on.
   2. Plug devices in one at a time, testing with the test switch between each device to determine what is causing the power issue.
   3. If all devices are plugged in and the light is working, the connections may have needed to be reseated, or it is possibly a power switch issue.
   4. Go to the power switch section of the power supply checklist for additional troubleshooting steps.
   
   
6. If the light does not come on:
   
   1. Disconnect the power from the hard disk drive, and then plug in power to the CD-ROM drive and determine whether the light comes on.
   2. If it does, follow the preceding information - "If the light comes on."
   3. If the light still does not come on, contact Gateway Technical Support.
   
   
7. Confirm that power from the power supply is connected to the motherboard. Remove all cards and cables from the motherboard, and press and hold the test switch for five seconds on the power supply and determine whether the green light-emitting diode (LED) comes on.
   
8. If the LED comes on, put the devices back in one at a time, testing between each device to determine what is causing the issue.

Suggest you change out the Power Supply, with a KNOWN to be good, and compatible Power Supply.

[Compatible:
Must have the correct power cables, and the correct amount of them.
1) 20-pin ATX main power cable;

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

2) 4-pin ATX +12 Volt power cable; (Power for the Processor)

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

3) SATA power cable; (Harddrive)

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

4) Standard 4-pin Peripheral power cables for the optical drive/s, and any fans;

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

5) Floppy Drive power cable. Not used for a Floppy Drive in this case, but power for the Card Reader;

http://www.playtool.com/pages/psuconnectors/connectors.html#floppy ]

Must have the correct Form Factor.
The Form Factor of the Power Supply for the ET1161 is ATX.
Size of the Power Supply case is approximately 3-1/2 inches Tall, 6 inches Wide, and 6 inches Long.

Should have 250 to 300 Watts.

Why am I stating this? Because you, or someone you know, may have an unused computer sitting around that you can borrow the Power Supply for a test. (GOOD and Compatible)

From your statements, and my diagnosis, I believe you have a bad Power Supply.
Weak voltage power rail.

Enough power to turn on LED lights, and spin fans, but not enough to turn the Processor on.
1) ALL of the LED lights combined 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.

I also base it on that eMachines uses low quality generic Power Supply's.
Bestec, or Delta, or another generic Power Supply manufacturer.

I also base it on that Power Supply failure is one of the leading causes of computer failure.

(If the inside of the computer, and the inside of the Power Supply, are not cleaned out on a regular basis as needed, this is also another contributing factor.

Use a can of compressed air for computers. Power unplugged to computer, and observe Anti-Static Precautions.
{Use the plastic straw in the ventilation holes of the Power Supply)


Feel the harddrive start? Yes. You feel the Platters inside the harddrive being spun by the spindle motor.

No Processor operating, there is nothing to find the boot record on the harddrive. The platters spin, but the Read/Write heads are not brought into play by the Actuator motor

[BIOS = Basic Input/Output System.
A small program that when the computer is first turned on, looks to see what devices are installed, does a Ram Memory count, then TURNS the Processor on, and hands the computer over to the Operating System.

An optical drive, (CD/DVD drive) will operate even if the Operating System doesn't. It's a mechanical device that uses 12 Volts.
(One example of an Operating System is Windows XP ]

How harddrives work;

http://computer.howstuffworks.com/hard-disk.htm

Open the case, and disconnect all the devices (CD, disk-drive, floppy-drive). Turn the computer on, and see if the fan on top of the CPU spins, if the fan in the power-supply spins, and (optionally) if a lamp on the motherboard lights-up.

If not, then you need to try a different power-supply.

Remove the side-panel.
Press the POWER button.
Does the fan inside the power-supply start to spin?
Does the fan on top of the CPU start to spin?
Is there any lamp on the motherboard that lights up?
Is there any noise (from disk-drive, floppy-drive, CD-drive) ?

If not, take your computer to a computer store, and get them to replace the power-supply. Hint: the smaller the computer-store, the more-likely that they will install for FREE, if you BUY from them.

no the floppy disk is not faulty, it is normal and required that the floppy disk drive light blink to indicate that the drive is working. And about the power on the power button might be stuck inside that is why it keeps turning on immediately you connect to main power

Hello my friend probably is a bios setting,somehow you hit default settings or flash your bios and you turned it on.Go into bios(hitting del on boot) and on the general page there will be a setting for a floppy drive, likely something like floppy 3.5" 1.4mb choose it and hit enter and you should be able to disable the floppy drive.If there is no setting, look for a HALT ON ALL ERRORS setting and change it to keyboard onl.

sounds like your motherboard lost a control chip. that makes the power supply cycle off, when m/b doesn't send correct signals to continue boot.

CHANGE THE POWER SUPPLAY.. BUT FIRTH..

1-UNPLUG HD AND TEST WITH FLOPPY OR CD BOOT DISK

2-UNPLUG YOUR MEDIA ROOM LIKE CD OR DVD AND TEST ONLY WITH FLOPPY BOOT DISK

3-UNPLUG VIDEO CARD AND ALL CARD ON YOUR MOTHERBOARD.. TEST ONLY WITH THE FLOPPY DISK AND ONBOARD VGA.. OR GOOD TESTED VGA CARD.

 

EXCUSE MY BAD ENGLISH.
