Where can i place in my motherboard power & reset jumper, i need diagram of my motherboard


For any desktop computer using Windows:

The main power cable coming from the Power Supply, is an ATX main power cable.

It is the power cable with the longest connector.
It will either be a 20-pin, or a 24-pin connector.

IF, this is directly towards an eMachine T2893 Desktop PC, it uses an Intel D845GVSR motherboard.

Also note that eMachines Support > Specifications, states the T2893 uses an Intel 845GV motherboard chipset,
( Chipset ),

http://support.gateway.com/emachines/PC/eMac/4176/4176sp5.shtml

Info on the Intel 845GV chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

This is the download link for the motherboard manual, for the Intel D845GVSR motherboard,

http://www.intel.com/support/motherboards/desktop/d845gvsr/sb/cs-008823.htm

Scroll down, and click on the blue -
Intel Desktop Board D845GVSR Product Guide (PDF)

The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click it may take up to 30 seconds before the first page comes up.

{ 10 seconds, fully loaded. Adobe Reader 10 (X), and medium speed DSL connection }

The plastic front of your desktop computer is the Front Panel.

The rectangular area of pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header. (Sometimes abbreviated FP1 on the motherboard )

Looking at your motherboard as it's installed in the computer case, the Processor is to the Top, Ram Memory to the Right, and the long white PCI slots to the Bottom.

The Front Panel header is on the Bottom of the motherboard, under the CMOS round battery.

There are two rows of pins.
4 across the top, and 5 across the bottom.
{ Top row 4 pins, space
Bottom row 5 pins }

The Top row of pins are numbered Even.
The Bottom row of pins are numbered Odd.

Starting from the Left side of the header going to the right, on the Top row;
{ Left side of the motherboard going towards the right side of the motherboard }

Pins 2, 4, 6, and 8. There is No pin 10.

Starting from the Left side of the header going 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.
Pin 1 is for the Positive ( + ) wire.
If the harddrive 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.

C) Pin 9 is for 5 Volt (DC) power. Not used.

D) Pins 2 and 4 are for the Power On LED light.

E) Pins 6 and 8 are for the Power On switch.

To the right, and up, is the BIOS Configuration Jumper Block.
3 pins.
Pin 1 is towards the CMOS battery.

Normal default is the jumper is on Pins 1 and 2.
To configure it is placed on Pins 2 and 3, BUT in a proper method.
Read on Page 37.

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.

Does the T2893 have to have an ATX power supply specifically for the emachine? I tried to upgrade to logisys 480w supply and the fans and a few lights come on, but the unit won't boot up.


there are TWO different power cables on the new machines. (not just two parts to the ATX)

one is the ATX like you are used to.

The other is a small four-prong plug (coming off of the power supply - look for yellow and black wires) find the matching receptacle on the motherboard.

good luck

T2893 desktop did not power on when I hit the power button


If you can find someone that has the same model, that is the best way to make sure it fits. Some other motherboards will fit, but you may have to do some work to get them to fit. The best way would be to try to do some research on your particular motherboard (mobo) on the internet. Sometimes it will have a manufacture’s name and model on it, try googling it and see what type it says it is (ATX, mini-ATX, AT, etc). One problem you may have is the power button connectors may not be compatible with your new motherboard if you get something besides an emachine mobo. If you are good at electronics it will not be much of a problem for you.

Unless you get an exact e-machines mobo, your OS will most likely not work at startup. Windows XP does not like wholesale changes like a mobo. When it sees that a major configuration change has happened it sometimes freaks out. Sometimes it will just ask you to re-activate windows other times it gets stuck in a reboot loop. Hard rive and CD rom should still work, provide you do not get too new of a mobo. Older HDD and CD drives were IDE connectors, newer ones have SATA connectors. Unless your mobo and power supply unit (PSU) have the correct connectors you will not be able to use them.

To the poster who asked if it could be anything else besides bad mobo. Yes it can occasionally be a bad power supply unit (PSU). A bad PSU does not necessarily mean no power, just not enough power to run the computer. You can try swapping it out with another one of equal or greater output watts. You can try removing the power connectors from the drives and then remove the memory and see if it changes the boot up procedure of your machine. More beeps, different beeps, no beeps, etc. Add one component back at a time to test. Make sure you get the same results and not just a one-time fluke start up. If a memory stick is bad, it usually is bad. A power supply or mobo can be flaky and fail some times and not others.
