EMachines Imperial GL VE-20021218 Motherboard Pin Out

I have a emachines that ate the motherboard listed above. I purchased a ASUS P4GV-LA motherboard as a replacement. The pin out for the LED for the HDD, Power LED and On/Off switch do not appear to be present on the ASUS motherboard. I want to obtain a pin out for the Imperial motherboard and compare it to the ASUS motherboard to make sure I do not fry the new motherboard. Any help with the configuration of either M/B would be greatly appreciated.

Re: EMachines Imperial GL VE-20021218 Motherboard Pin Out

I have an HP pavillion a305w with the same Imperial MB, and I replaced my MB with an ASUS P4SGX-MX.
from your case, the yellow/black goes to the IDE Led, the green/black goes to the POWER Led, and the red/black goes to the POWER SWITCH.

Re: EMachines Imperial GL VE-20021218 Motherboard Pin Out

Normally on the board there is silk printing to state what connection goes where. Also on the black connector i.e. power LED there is a small arrow that goes to pin 1 of the POWER LED pins.

Hope that was any help thanks J

I am trying to find the power switch diagram for an emachine t6520 thanks

On a Asus motherboard its not designed for eMachines systems because they come with a proprietary setting on the case. So what you need to is take the emachines motherboard that you took out and take the new motherboard that you bought and match the two. If there is a difference then you need to return it or buy a new case and you shift all the hardware from the emachines to the new case. If not buy a similar replacement board from emachines or ebay and you can find one and buy it. The Power setting is on all motherboards but some are different then others.

Need a motherboard diagram for an emachines w3503 .

The eMachines W3503 uses an Intel D101GGC motherboard.

eMachines Support isn't going to show you squat.

This is Intel Support, and the download page for the Motherboard Manual, for the above motherboard,
(It's a PDF file. Give it time to download)

On the above page left-click on -

Need some information about that motherboard, or how to understand the Front Panel header pinouts on the motherboard, state in a Comment.

Front power switch broken. Bezel won't come off easily. Thought we could just get a switch and install on the back but don't know which of the colored pairs of wires go to the original switch in the...

I would suggest this generic Power On switch,


and the Red, and Black twisted pair of wires go to the Power On switch.

Your statement of ,"....don't know which of the colored pairs of wires go.....", leads me to believe you may have all of the Front Panel wires disconnected.

How about information as to where ALL the Front Panel wires go?
(Provided I have correctly interpreted your statement)

Back in the time that the eMachines T2542 was made, TriGem was the motherboard manufacturer.

The Model Name of the motherboard is Imperial, and the Model Number of the motherboard, could have been one of four variations offered.

Model Name: Imperial
Model numbers could be G, GL, GV, or GLVE
(Imperial G, Imperial GL, Imperial GV, or Imperial GLVE)

ALL four variations used the same Front Panel header.
(The connector on the motherboard the Front Panel wires connect to, is named the Front Panel header)

I would like you to view this page,

Scroll down to the heading -
Trigem Imperial Front Panel Header Pinout.

A) Pins 1, 2, and 3 are for the Power On LED light.

B) Pins 5 and 6 are for the HarDDrive activity LED light.
(Pin 4 is not used. NC. No Connection)

C) Pins 7 and 8 are for the Power On switch

D) I wouldn't connect any wires to Pins 9 and 10, nor Pins 11 and 12

E) Pins 14 and 15 are for the Reset switch. (The button you press to restart your computer.
If the T2542 doesn't have a Reset switch, don't worry about it. There are many other ways to restart your computer)

F) Pins 17 18, and 20 are for an internal speaker.
This speaker is used for BIOS Beep Codes.

In the chart to the right, you will see GRD used many times.
GRD stands for Ground.
ANY Black wire in the twisted pair of wires, is a Ground wire.

Most of the eMachines I have worked on, use a Red, and Black pair of twisted wires for the Power On switch.
I could be mistaken on the T2542.

Best method, is to follow the color code of the wires that come from Pins 7 and 8, and be sure.

Need the pin assignments for the mother board

On most motherboards the front panel connections are printed in the connectors on the motherboard. When you connect the various LED indicators and when you power up and they do not light up then just switch the connectors around, because they are are polarized.
You can go to the motherboard WEB site (ASUS) to download a manual, the manufacturer and model number is printed on the motherboard.

ASUS P4GV-LA motherboard swapout

It's true that P4 boards are not manufactured any more. But again, are you sure that it’s the motherboard which has problem, the SMPS (power supply might have some problem.) might be faulty too. Check the SMPS first.

Upgrade to a new motherboard?

I think there may be another issue.. It could be the power supply.. Have you tried a new one?

Have you installed any additional ram lately?

You can use the old XP software with a new motherboard, but it can be a pain in the **** to set-up if it is the OEM version of Windows, or a Recovery Disk that came with your machine..

What you could do, if you bought another motherboard, find someone with a Genuine Windows XP disk, and use your Product Key to install it..
