    You mean to say there is a green LED on *********** board which is not glowing or there is a green glowing light. Remove the power cord for some time from smps and then reconnect and try if then also nothing happens just check wether smps is working or not just unplug the power supply cord to the motherboard from smps and check the output it should be between 12-18 volts dc. If not getting any voltage or getting too low then your smps needs to be changed

My computer says it has no signal. How can I fix this? When I turn itinerary it says no signal then the green light under my monitor turns orange.


Open cpu cabinet then you can motherboard pull cmos cell from motherboard for 10 seconds then put it back reconnect RAM memory reconnect both connection to harddrive .Make sure motherboard is not ground with cabinet. Then check. Also when you power up the computer press F8 key 5 to 6 times then if you are able to see safe mode and other menu enter in "Enable vga mode" then go to display property and change screen resolution to 1024*768 then apply. Let me know if you need further assistance. Thanks for using FixYa.

I have a T2893 model that is probably 10 years old. The hard drive just quit on me and I cannot boot back up. It appears completely dead. I changed power plugs to ensure that it was not the power supply. I...


1) Install the harddrive as a slave drive in a known working computer.

2) Install the harddrive into an economical external harddrive enclosure, and plug the USB cable of the enclosure into a known working computer.
[IMHO the better of the two options]

The eMachines T2893 uses an IDE harddrive, (IDE is also referred to as PATA)
This is an example of an IDE external enclosure,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1337265&CatId=2779

As for the T2893 it could be a bad power supply, and worst case scenario, a bad motherboard also.

Granted the power supply may seem to be working, (Bestec 250 Watt), but it may have a weak voltage power rail.

Enough power to light lights, and maybe spin fans, but not enough for the Processor.
1) ALL the lights use less than 1 Watt of power
2) EACH fan uses 2 to 3 Watts
3) A typical Processor can use 51 to a 125 Watts.

The T2893 comes with an Intel Celeron D 330.

http://en.wikipedia.org/wiki/List_of_intel_celeron_microprocessors#.22Prescott-256.22_.2890_nm.29

The Celeron D 330 can use up to 84 Watts. (Under the heading TDP in the chart )

In essence the harddrive may not be bad.

When you press the Power On button, you are closing a circuit that feeds 5 Volts to the Power Supply. Soft Power On function.

[Brought in, to replace the old style of pressing the plastic Power On button, which in turn presses against a steel rod, which in turn presses against a Power On switch, attached directly to the Power Supply ]

Power goes to the motherboard. The first chipset to receive power, and to initialize is the BIOS chip.
[Chip and Chipset are slang terms to represent I.C. Integrated Circuit]

Bios looks to see what devices are installed, does a Ram Memory count, turns the Processor on, and hands the computer over to the Operating System.
[Windows XP is an example of an O/S]

The operating system is located on the harddrive.
You don't have enough power to turn the Processor on, so there is nothing to process information.
Nothing to find the operating system.

Two of the major faults reported for the T2893, are the Bestec 250 Watt PSU, (Power Supply Unit), and the motherboard.
The primary failure is the Power Supply. When the power supply fails, it has a nasty tendency to take the motherboard with it.

What actions to take, to possibly solve the problem with the T2893, provided the harddrive works?
Suggestions:

1) Test the Power Supply. See if the voltages are correct, and specifically the 12 Volt power.
There are three main voltages.
A) Yellow insulated wires are 12 Volts
B) Red wires are 5 volts
C) Orange wires are 3.3 Volts

ANY Black wire is a Ground wire.

Do you have a multimeter? An economical multimeter can be purchased for around $10 to $12.
(Many stores carry them. An auto parts store is one place)

There is also a power supply tester. Economical versions are around $20.
The 12 Volt power can be 11 to 13 Volts. Anything below 11 Volts, and it's time for a new power supply.

Power supply diagnoses to be good, check the motherboard. Visually look for bad Electrolytic Capacitors.
eMachines are known for using cheap quality Electrolytic Capacitors.
Saves the computer manufacturer money, which they use to sell budget priced computers. (All eMachines are budget computers)

http://www.capacitorlab.com/visible-failures/index.htm

If the motherboard is bad, I have seen replacements offered online.
One motherboard offered had the price of $90.

Now you could be looking at $30 to $50 for a decent replacement Power Supply, and another $90 for a motherboard.
Believe it would be best served to purchase another computer, IMHO.

Have any questions concerning this, please post in a Comment.

I agree...sounds like a power supply problem. Typically a bad power supply will not damage the motherboard. It should still be functional.

E machine no power


Make sure the RAM is seated, the CPU, any video card and the Power supply is properly connected.

If you power it on, still get no POST (beep at startup from the PC speakers) its time to replace the motherboard.

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.

Emachines 1900+ gets power to the monitor and computer but wont boot


Buy a dianostics card, and find out if its the RAM, CPU, OR Motherboard. (sounds like a ram or CPU problem though) if you have more than one stick of ram in the system, take one out, and power it up, if still not response, to the other stick out, and put the stick you took out the first time, and put it back in.
