Emachine wont power up .board led is on but no initialization from the power button.unplugged everything and started with just processor and memory and nothing changed power supply and same result

    I am having the same problem with my E-Machines T2882 PC Desktop . I took the cover off and I could see a green LED glowing on the mother board. The LED is on as long as the computer is plugged-in. Pressing the on/off switch makes no difference.



    None of the three cooling fans run--again it doesn't matter how many times I press the on/off switch.



    Any thoughts on whether it's the on/off switch or the power supply?



    Thanks.

E-machine modem wont turn on the fan and little yellow light on bottom are on


This is not a full solution, it is a partial solution, and something I would like you to try;

1) Unplug the computer from power.
2) Press, and hold the Power On button in for a count of at least 5 seconds.
Let go of the Power On button.

Perform this procedure 2 more times.

3) Plug the computer back into power. WAIT 1 minute, turn the computer on.

If the computer doesn't turn on you have a bad Power Supply.

Weak voltage power rail

Computer may have enough power to light LED lights, and perhaps spin fans, but not enough power to turn the Processor on.

A) If ALL of the LED lights were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use from 51 to 125 Watts of power.
Maximum power consumption will depend on what Processor it is.

So you see a Power Supply with a weak voltage power rail, will have enough power to light LED lights, and perhaps spin fans, but not enough power to turn the Processor on.

[ You press the Power On button.
The first chipset on the motherboard to receive power, is the BIOS chipset. { Basic Input/Output System}

BIOS looks to see what devices are installed, does a Ram Memory count, turns the Processor on, then hands the computer over to the Operating System.

{Windows XP and Windows 7, are but two examples of an O/S }

I do not see what model number of eMachines you have, listed here.
If it is Not one of the slimline models, you may want to try swapping the Power Supply with a KNOWN to be good one.

I post this with the thought in mind, that there may be an unused desktop computer around, and perhaps you could borrow it's Power Supply for a test unit.

This may sound far fetched, as far as having a spare working desktop computer around, but I have had a reply from a poster who stated their relative had one.

If the Power Supply works, you know what the problem is, and how to solve it. Replace the Power Supply.

Replacing a Power Supply in a desktop computer may seem daunting, if you have never performed this procedure before.
It really isn't.

I can guide you on here, and add links which I believe may be beneficial.

Need the pin Config for the Motherboard pwr switch and hdd switch for a Emachine T2672 and pwd led thanks


Pin Configuration = Pinout

The Front plastic panel of the computer is the Front Panel.
The area of pins on the motherboard that the cables (Wires) go to, is the Front Panel header.
Front Panel header pinout.

The motherboard used in an eMachines T2672 desktop computer is an FIC AU31 motherboard.
Made by First International Computers (Inc.) for eMachines.

http://www.e4allupgraders.info/dir1/motherboards/socketa/au31.shtml

Orient the motherboard like it is in the photo, so we are both looking at it in the same direction.
{Processor to the top, Ram memory slots to the right, white PCI slots to the bottom. The way it sits in the computer case}

The Front Panel header, is a small black rectangular block that sits horizontally, at the far right bottom corner.

It has two rows of pins.
4 across the top, and 5 across the bottom.

(The small rectangular block above it, is for connecting a Power On LED light that has 3 wires. More on this in a moment)

The pins are numbered.
The pins are numbered Evenly across the top, and Odd across the bottom.

Starting from the Left side going across to the Right, on the Top row;
Pins 2, 4, 6, and 8.
There is No Pin 10.

Starting from the Left side going across to the Right, on the Bottom row;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED light. (HDD LED)
Pin 1 is for the Positive wire ( + )
(If the LED light is dim when operating, switch the wires around)

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used. (Reset button)

C) Pin 9 is Not Used. (NC. No Connection)

D) Pins 2 and 4 are for the Power On LED light, IF it is a 2 wire LED light.
Pin 2 is for the Positive ( + ) wire.
(If the LED light is dim, switch the wires around)

If the Power On LED light has 3 wires:
Use the Power On header above the Front Panel header.
This rectangular block has 3 pins.

Starting from the Left side going to the Right; Pins 1 , 2, and 3.
Pin 1 is for the Positive wire.
Pins 2 and 3 are Ground wires.

E) Pins 6 and 8 are for the Power On switch. (Power On button plastic assembly has an ATX power on switch inside it)

This is a link to a free motherboard manual, for the FIC AU31 motherboard. It is in Zipped file form.
(A Zipped file is a compressed file. It is used for one, to send a large file over the internet)

If you do not know how to unzip a file, post in a Comment, and I'll lead you step by step.

In the list on the left side, left-click right on the file name - AU31

[ P.S.
The motherboard chipset is an Nvidia Crush 18G + MCP AGP
It is an Nvidia Force 2 chipset,

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_chipsets#nForce2

Supports Processors that are AMD, and fit in a Socket A processor socket.
(Socket A is also known as Socket 462)

Supports AMD processors that have either a 200MegaHertz Front Side Bus, or a 266MHz FSB, or a 333MHz FSB.

AMD Athlon XP processors with either a 266MHz FSB, or 333MHz FSB.
From the 1500+ model up to the 2800+ model.

AMD Duron processors with a 200MHz FSB.
From the 800MHz to the 1.3GHz models

(AMD Athlon XP is the top of the line. Then it's Duron, then Sempron.
A Sempron processor has half of the L2 cache that a comparable Athlon XP does)

Ram Memory is DDR Sdram at either 200MHz, or 266MHz, or 333MHz, or 400MHz.
Depends on the Processor used.

(Ram Memory typically operates at half of the frequency rate ('Speed') that the Processor does.
If the processor's FSB is 333MHz, you can use 400MHz DDR Sdram. {PC3200}

Confusing I know.
DDR Sdram is 'double-pumped'. It is actually 200MHz for PC3200.
This is close to half of 333MHz.

Processor has an FSB of 266MHz? Ram memory used will be 266MHz. Remember, it is actually 133MHz for the ram memory. (PC2100)

Need an AMD Athlon processor?
I found this place years ago. Not advertising for them. Just computer geeks sticking together, and sharing information. (I have bought a motherboard from them, and it works fine),

Dell 2400 desktop pc will not turn on. Mother board flea led light does turn on.Tested power switch and wiring okay.I did swap power supply pack from a good working 2350 Dell pc same problem any...


Try to remove all components all drives (hard drives, cd/dvd roms, floppy drives, etc), all additional cards (modem, video card, sound card etc), remove the memory. Just leave the motheboard, proc and power supply. Before disconnecting everything completely discharge power by holding down the power button while the computer is unplug from the power. It should clear the flea light on the motherboard.
Test it again with just the motherboard, processor and the power supply. If still no power then most likely it is the motherboard since you already put a known good power supply. Motherboard has higher failure rate than the processor. You can swap a known good processor if there is.

Check the fuse on the inside of it and see if it is not blown, if not blown change it any way it may not look like it is blown but it is hard to tell, and see if that work.

Wont start up


Hello,

is there any power indication? if there is then please unplug the unit from the power outlet and then open the casing and try to refix all the connection inside. If not resolve then try to test one by the parts starting from the processor, memory,VGA Card, mother board, hard drive. if found no error in its component then probably the the operating system. you have to reinstall the operating system and all diver and application program.

if it no power indication then test first the power supply before doing the suggested above solution.

If you are getting absolutely nothing, and it seems you have checked all the obvious, then I guess its just the board given up

Power button wiring


A quick google determined your emachines model w2040 is equipped with FIC motherboard AM37. Download the manual from
http://www.fic.com.tw/support/motherboard/motherboard.aspx?model_id=107
You'll find the pinout info for your wiring on page 13.
Most motherboards also have the pinouts silkscreened onto the board itself.
