Emachine total black , this are on fan


LED lights are on? Fans spin? I suggest you have a bad Power Supply.

1) eMachines are noted to have low quality Power Supply's.
Saves eMachines money so they can sell budget computers.

2) A bad Power Supply is one of the leading causes of computer failure. I have, (Had actually), a shop half full of computers with this 'ailment'.

Some caused by the owners never cleaned out the inside of their computer, nor the inside of the Power Supply, with a can of compressed air for computers on a regular basis as needed.

3 to 5 years without cleaning the inside of their computer.
Mice could have made nests inside easily, with the 'Gunk' that was there. A bald eagle could have too. Rant off.

Others, caused by the computer manufacturer used a low quality Power Supply.
Low quality components used inside.
One of the major components that fails, is caused by a particular Electrolytic Capacitor that is used.

http://en.wikipedia.org/wiki/Capacitor_plague

3) Power Supply's used in PC's are a type of SMPS.
(Personal Computer. Statement holds true no matter what type of personal computer it is)

[ SMPS = Switched-Mode Power Supply
PSU = Power Supply Unit
All terms relate to a Power Supply used in a PC ]

A bad Power Supply will have a weak voltage power rail.
There are three major power rails used in the ATX form factor Power Supply, for an eMachines T6420 desktop computer.

A) The 3.3 Volt power rail (DC)
B) The 5 Volt power rail (DC)
C) The 12 Volt power rail (DC)

(Two D cell flashlight batteries produce 3 Volts DC)

A Power Supply with a weak voltage power rail, may have enough power to light LED lights, and spin fans, (or spin a few times, ans stop), but won't have enough power to turn the Processor on.

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.

eMachines T6420?
Uses an AMD Athlon 64 3400+, processor.
(Socket 939)

[The motherboard used is an MSI ms-7207
Also known as K8NGM2-L ]

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T6420

This Processor can use Up To 89 Watts.

http://en.wikipedia.org/wiki/List_of_amd_athlon_64_processors#.22Newcastle.22_.28CG.2C_130_nm.29

No Processor running, No computer.
No computer = No Video Signal

Suggest using a KNOWN to be Good, Compatible power supply, for a test unit, if available.

Should be the ATX form factor.

Approximately 6 inches Long, (15.24cm), 6 inches Wide, (15.24cm), and 3-1/2 inches Tall. (8.89cm)

250 Watts.
Correct amount of power cables, and the correct type.

I NEED TO KNOW HOW TO CONNECT THE POWER SUPPLY FOR AN EMACHINES T1120 COMPUTER. CANNOT FIND A SCHEMATICS DIAGRAM ANYWHERE.


After reading an article about Emachines awhile back, I found out the reason you can't find the schematic- it isn't available, as some motherboards are made specifically for Emachines and therefore not distributed, as they might normally be, but again, others are, but you have to identify them and go through another source to get them- Emachines, appartantly, will not supply them. All is not lost, however...all motherboards have, basically, the same hookups and connectors for the power supplies, hard drives, etc.- they are standard. I found a web blog that explains the power switch, reset, and power led, which will help. Here it is: http://www.computing.net/answers/hardware/emachine-power-sitch-wiring/56545.html
This site will explain about the 24 pin connector from the power supply
http://www.tomshardware.com/forum/53750-7-installation-manual-rs480m-w3400-emachine-motherboard
If you google "motherboard wiring" you will find sites that have illustrations of the motherboard, and explain which connectors go to which sockets, and how to identify them.
With a little patience and determination, you should be able to hook everything up from the various blogs on the net. Hope this helps.

Change the order so that the CD boots first. Try to run Repair from the Windows CD. If unsuccessful, you'll need to reinstall Windows.

Emachine t2824 board diagram


Here is the diagram that shows you how to hook up the wires:

http://www.fixya.com/uploads/images/284ECAC.png

If you still have no video then reseat the memory one stick at a time in one slot at a time.

If you still have no video then reseat the cpu into its slot.

If still no luck try a different stick of RAM by trying it one slot a time.

Last step, unhook the power connectors from your device so the only power connectors that are connected are the power to the motherboard and the p4 connector to the motheboard. Also make sure your power supply is set to 115v. Its the red switch on the back of the power supply.

If none of this works, then the motherboard is bad. Hope this information helps.

TRYING TO HOOK UP MU POWER BUTTON NEED TO KNOW


Hi there
The front panel connectors are mainly,
  • harddisk activity connector
  • power switch connector
  • reset switch connector
  • power LED connector
  • speakers connector
  • USB connector
Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.
