T2958 motherboard connections

My son swapped out the hard drive to test it in another machine, (a different problem). When he reinstalled it the computer would not power up. Power is getting to the mother board because a little led lights up on it. However, no light on the power switch and no fans run when I press the power button. I took off the front panel to see if the power switch is mechanically working (a problem I once had with another emachines). I pulled the wires from the power switch, HDD led, and power led off the motherboard all at one time thinking they were one plastic connector. To my surprise, they are separate. Can you help with pin location and polarity for replacement?

You are also an apprentice speller I see. I'll never know how you can just go online and display your illiteracy like that. Five spelling errors in one sentence. Didn't go to school or didn't pay attention did you? How can you expect to fix your computer?

Re: T2958 motherboard connections

I replaced my mobo in an emachine t2958 yesterday, today it doesnt power on so im off to get a power supply as well *should have read the board first*

my question is that i have the 2 optical drives set up as master slave.
i have the HD plugged to a pci slot since the board I am using doesnt have 3 IDE ports
the only other power plug that is left over (no idea what its for) is labeled P7 from the original powersupply

if I manage to find a setting for P7 and the supply fires up then i have saved myself having to replace the power supply, correct?

Re: T2958 motherboard connections

Sounds like a power supply problem, I would check out a power supply tester, usually about 19 bucks, but now adays you can buy a decent power supply for 20 bucks, but before you can and spend money, be sure that everything is connected properly. im searching google now for the pin locations, but if you know what type of motherboard, it will make my search so much easier. ***reply to your other post*** all you need to do to get the hard drive to work in another machine is format the Master Boot Record

Re: T2958 motherboard connections

Concerning the pin locations and polarity they are printed on the motherboard close to the pins. Also, your power supply is failing. I have a customer with the same problem, the power supply needed to be replaced and also the motherboard because it would not even boot to post.

My emachine model t2958 won't turn on.

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty

computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical or fan lead can cause you problems

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in

check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat

Thermal compound is a sticky paste that is placed directly onto the CPU.

Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

hope this helps

I have an 830GM and am suspicious of a hard drive crash or a motherboard failure and was wondering how to diagnose?

try replacing or swapping the hard drive with another machine and see if it happens again and on which machine if both machine's crash both MB and HD could be bad, If your machine with different HD works fine then it most likely was the HD If not then the MB might be at fault

Yes but with one stipulation. If they each have different hardware (like video cards for example) the drivers may have to be reinstalled if it is windows that is on these machines.

I have a T2958 and toof the face off. Can you

eMachines doesn't give out this kind of info, and I don't have one in the shop.
eMachines also had the habit, of using a few different manufacturer's of motherboards. Intel, TriGem, MSI, Asus,and FIC to name five.

Plus eMachines would use whatever was available at THAT moment, when they were producing that particular model line. (Not stating the T2958 specifically. Whatever model line they were making at the time)

Plus at the time the T2958 was made, Gateway had bought out eMachines. (eMachines later bought themselves back)

However all is not lost here. At the time the T2958 was made the motherboards were manufactured by Intel.

The Intel D845GVSR
Uses the Intel D845GV MCH, and the Intel ICH4 southbridge chipset

(MCH. Memory Controller Hub. Intel's naming for their Northbridge chipset)

You are looking to see where the wires go, on the Front Panel header of the motherboard, from the Front Panel of your computer.

(Front Panel header on a motherboard, is essentially where the wires go that come from the Front Panel of the computer. When referring to a connector on a motherboard, a connector is a Header.

The Power On switch wires, HDD Activity Lamp, Reset switch, {If used}, and Power On Lamp, are located in the Front Panel, for your computer)

{Front Panel = 'Face'}

As stated, eMachines does not give out this info.
I just need your patience, and your eyes. I need you to compare a photo of a motherboard to yours.

When you open your computer case, the side cover should come off of the Left side.
The back of the computer will be to the Left, the front to the right.

The Processor will be at the top of the motherboard, and the Ram Memory slots will be to the right.

Observe the motherboard photo at the top of this page,

Orient in your mind so that the motherboard in the photo will have the Processor to the top, and the Ram Memory slots to the right.

Should you have no idea of what I'm referring to here, please come back, and state so in a Comment.

The Front Panel header is composed of three individual headers, (Connectors) for this motherboard.

J9F2, J9G1, and J8H3

The J9F2 is for the USB ports used in the Front Panel. We won't be concerning ourselves with this header.

J8H3 is located to Right side of the CMOS battery. It has two pins sticking up.
This is where the Power On LED light plugs into, IF, the Power On LED light has Two wires, and the light is one solid color when lit up.

J9G1 is located below the CMOS battery, and is located on the bottom edge of the motherboard.

There are two rows of pins sticking up.
The rows are parallel to the edge of the motherboard.

The top row has 4 pins.
The bottom row next to the edge of the motherboard has 5 pins.

The pins are numbered from the Left, going to the Right. There MAY be a number 1, or 2, stamped on the motherboard.
I wouldn't count on it.

The top row of pins, going from the Left towards the Right are,
2, 4, 6, and 8.

The bottom row of pins going from the Left towards the Right are,
1, 3, 5, 7, and 9
There is no Pin 10.

1) Pins 1 and 3 are for the Harddrive Activity light. (HDD)
2) Pins 2 and 4 are used for a Power On LED also.
3) Pins 6 and 8 are for the Power On switch

Should you have more questions concerning this, please state so in a Comment.

Emachine D2880-No Power

Probably yes, the poiwer-source may be delivering "dirty" power (happens also when using a back-up generator, as in the power in the building goes out, or when used in an old RV, and the back-up kicks in) <--- is a safety feature to protect the CPU. Try also a different powerstrip, or head off to the neighbors and try their plug before swapping out the power supply.

In the end, you may wish purchase an inexpensive clone-tower, swap out the HD and processor (if you are spending too much time and money trying to band-aid the old one)

Hope this helps!

T2958 continuous startup cycle

It sounds like there may be an issue with the memory chips. If available, take a memory stick that matches the type of memory you need for your computer. Take out all memory sticks on the motherboard and try the new memory stick in the first memory slot and see if you get the error. If so, then try it in the second memory slot.
