How to connect the power led,power sw,hdd led on e-machine t2240


Apologizes your question hasn't received a solution until now. I have been 'away from my desk' for a while.

The eMachines T2240 desktop pc uses an Intel D845GVSR motherboard.
So let's go to Intel Support for more information, and to the specific product download page for the Intel D845GVSR motherboard,

Intel Desktop Board D845GVSR Product Guides


On this page left-click right on the blue title -
Intel Desktop Board D845GVSR Product Guide (PDF)

This is a PDF file. The computer you are using has Adobe Reader on it which uses PDF files.
After you have downloaded the PDF file go to the top left and hover your mouse cursor on the rectangular icon. (To the left of the Up/Down arrows and Page: )

Hovering your mouse cursor over this icon will briefly reveal -
Toggle Sidebar. Click on this icon.
Now click on the icon to the immediate right of it. (Show Document Outline)

Scroll the Show Document Outline sidebar down until you see the heading - Connecting Internal Headers -
Now click on the heading immediately underneath it -
Connecting the- Front Panel Header -

[The front of your computer is the Front Panel. The area of connecting pins on the motherboard for the Front Panel is the Front Panel Header ]

On Page 11 in the Product Guide we see that S designates the Front Panel Header.
On Page 31 in the Product Guide it shows the Front Panel Header pinout. (The Front Panel Header is designated by C in the illustration)
Again on Page 32, it shows where the Front Panel cables connect to.

In case you are not able to view the Product Guide;

Viewing the motherboard installed in the computer case, the Front Panel Header lays parallel to the bottom of the motherboard, at the Bottom Right.

It is rectangular in shape and has 9 pins.
4 pins along the Top, and 5 pins along the Bottom.

The pins are numbered Even along the Top row;
Starting from the Left side of the Front Panel Header going to the right;
Pins 2, 4, 6,and 8. There is NO Pin 10.

The pins are numbered Odd along the Bottom row;
Starting from the Left going to the right;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the Harddrive Activity LED.
Pin 1 is for the Positive ( + ) wire. Pin 3 for the Ground wire.
In case the HDD LED is dim when the HarDDrive is active, switch the wires around. (Computer off and Anti-Static Precautions used)

B) Pins 5 and 7 are for the Reset switch, IF a Reset switch is used.
Pin 5 is for the Ground wire.

C) Pin 9 is for 5 volt ( + ) power. Not Used.
(Usually the motherboard manufacturer uses this pin to test the motherboard)

D) Pins 2 and 4 are for the Power On LED.
-> Believe Pin 2 is for the Positive ( + ) wire.
If PWR LED is dim when computer is on, switch the wires around.

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

There is No Pin 10.

Hello i need to know how to reconnect the computer case wires to a sr1703wm compaq motherboard


Hello.

The Compaq Presario SR1703WM desktop computer, uses an Asus A9AE-LE motherboard.
HP/Compaq's name is AmberineM - GL6E

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00496280&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=1815742

1) I would like to start with the Front Panel wires.
The Front panel, is the plastic front on your computer tower, where the Power On button, Power On LED, and so on is located.

The Front Panel header is the connector on the motherboard, where the cables, (Wires), from the Front Panel connect to.

Looking at the HP Support link above, I would like you to scroll down the page to the illustration of the motherboard, and the photo of the motherboard under the illustration.

Looking at the illustration observe the bottom Right corner.
F_PANEL1 indicates the Front Panel header.

Note there are 4 pins going across the Top, and 5 pins going across the Bottom.

Looking inside your computer, the motherboard will be located in a different position, compared to the illustration.

The Front Panel header will be located Vertically, (Up, and down)

Note that there is a twisted pair of Black, and Red wires.
These wires form the Power On cable.
They come directly from the Power on switch.

There is a twisted pair of Yellow, and Black wires.
These wires form the Harddrive Activity LED light cable.
(HDD)
When the harddrive is active, this LED flashes.

There is a twisted pair of Green, and Black wires.
These wires form the Power On LED light cable.

The wires, (Cables), should be in one Black connector.

Looking at the Front Panel header in your computer, align the Black plastic connector's socket holes, with the pins sticking up out of the Front Panel header, on the motherboard.

Note that the Front Panel header is rectangular in shape. There is 1 pin missing.
The Black connector coming from the Front Panel of the computer, has one socket hole blocked off, to match.

Align the four socket holes in the Black connector, to match the 4 pins sticking up out of the Front Panel header, on the motherboard.

The other 5 socket holes in the Black connector, will match up to the 5 pins sticking up, automatically.

Use care, and you may need a bright light to assist.
These pins can be bent quite easily.
(Also watch your fingers, as the ends of the pins are S-H-A-R-P!)

2) Where it states CLRTC (CLPWD under it), is the Clear CMOS jumper.
Suggest you leave it alone.

3) Where it states F_ USB1, and F_USB2, is where the USB cables from the front of the computer connect to.

(The USB ports on the front of the computer's Front Panel.
F_USB1, and F_USB2 headers on the motherboard, are shown on the illustration to the Left, of the Front Panel header. F_PANEL1)

The plastic connector on a USB cable coming from the Front Panel, has an orientation just like the Front Panel header cable does.

There is 1 pin missing on the USB header on the motherboard.
There is a blocked socket hole in the USB cable's connector.
Align the connector to match the pins.

Doesn't matter which USB cable from the Front Panel, that you connect to the USB headers on the motherboard.
BIOS will find them, and assign an IRQ to each, once you turn the computer on.

All you will see at a first glance is a series of thick Gray insulated cables, coming from the Front Panel of your computer.

If you follow the cables by eye, you can see where the USB cables are connected to the back of the USB ports, on the Front Panel.

You may, or may not, have to remove the Front Panel to see more clearly.

Computer case open, look inside towards the Front Panel.
There is a Green plastic tab towards the Top.

This locking tab is depressed Towards the Inside of the computer, to START to unlock the Front Panel.

Towards the bottom in the same plane, is a Black locking tab. This tab is pulled Towards the Outside of the computer.
There is another Black plastic tab on the opposite side.

At the Bottom are two more Black plastic locking tabs. These are depressed down, towards the Bottom of the computer case.
One on one side, one on the opposite side.

Start by depressing the plastic Green tab, and gently easing the Top of the Front Panel, slightly out.
Then go to the two Black plastic locking tabs located towards the Middle, and depress them.

Ease the top of the Front Panel out a little more.
Finally go to the two Black plastic locking tabs located at the Bottom, and depress them.
Ease the Front Panel off.

(NOTE*
Your computer's Front Panel may not have locking tabs located at the bottom.
Just locking tabs located up from the bottom, more towards the middle)

It's no picnic for your first time, but once you have done it, it becomes easy. (Ummm, Easier!)

4) The Firewire (a1394) cable on the Front Panel, connects to the F_1394 header on the motherboard.
In the motherboard illustration the F_1394 header is located to the Left, of PCI2

Need any further cable connections, post in a Comment.

Pins 5 and 7 are for the Reset switch.
Pin 7 is for the Positive connection. ( + )

Pin 9 is reserved, and may not be used.

Pins 2 and 4 are for the Message LED light. (LED = Light Emitting Diode)
Power On LED light.

Pins 6 and 8 are for the Power On switch.
There is No Pin 10.

If the cables (Wires) are not marked coming from the Front Panel, you will have to remove the Front Panel, and trace where they go.

You will be able to physically see where wires go to the Power On switch, Power On LED light, HarDDrive activity LED light, and so on.

B) 24-pin ATX main power cable:

Only plugs in one direction. Plugs next to the blue IDE connector on the motherboard. (To the right of the ram memory slots)

C) 4-pin ATX +12 Volt power cable.
Looks like this,

Plugs into the whitish square 4 socket hole connector on the motherboard, next to the Processor socket.
(On the motherboard illustration this connector is labeled - ATX12V1

D) Processor Fan:
Connects to the 3-pin CPU header on the motherboard. Right above the ram memory slots.

E) Harddrive:
You have a SATA harddrive. (500GB in size)
Connects to the SATA 1 header on the motherboard.
The SATA 1 header on the motherboard is Black in color.

The data interface cable has 7 pins.
Looks similar to this, (May not have a 90 degree elbow though),

NOTE*
If your SATA harddrive has a place for a SATA power cable, AND a 4-pin Peripheral power cable, DO NOT plug both power cables in!!
This will lead to damage of the SATA harddrive!

The standard 4-pin Peripheral power cable looks like this,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

(The standard 4-pin Peripheral power cable connector, has had a misnomer for years as a Molex connector.
Molex was the first design implemented when this style of connector came out.
The name stuck.
It is the same as calling an adjustable open-end wrench a Crescent wrench)


F) Optical drives:
If you have a DVD burner drive it plugs into the SATA header 2.
(Uses the same style of SATA data interface cable, as the SATA harddrive)

If any of your optical drives are IDE, they plug into the blue IDE header, next to the ram memory slots.

This is what a flat ribbon IDE data interface cable looks like,

G) The Floppy Disk drive, (If your computer came with one), plugs into the FDD connector shown on the motherboard illustration.
(Black in color, right above the 24-pin ATX main power cable connector)

How do I connect the front usb wires to my fic c51g motherboard header?


How to Install Front USB by Connecting Front USB Ports to a Motherboard?In order to have front mounted USB you must have 3 things.
  1. A case with USB ports in the front of it.
  2. A motherboard that supports front USB (usually)
  3. Appropriate wiring between the USB port and the motherboard
A case can support front USB in two ways: via a pass thru connection, or via a port to header connection. The former, pass thru connection, is compatible with all motherboards that have USB ports. Pass thru front USB Pass thru front USB works by having the ports on the front of the case connect to either a standard USB cable, or a fairly small rounded cable. The cable goes from the front of the case to a special slot cover with either a hole (for the standard USB cable) or a special connector for the rounded cable. If the pass thru USB had a standard cable, then you would simply plug the standard cable into one of your back USB ports. If it had a rounded cable, then you have a secondary attachment with something that looks like an old style SCSI connector. The attachment plugs into both the slot cover, and the back USB ports. The draw back of pass thru front USB is that you lose the ports in the back.

Many 3rd party devices that add front USB to a system use the pass thru system. A good example is this now discontinued Front IO panel

Front USB via a Port to Header connection In order to hook up a Port to Header connection you have to make sure that the wires from your port will connect to your motherboard's header. To do this you need to know what header you have, and what type of connector you have on the wires. You'll find information on both below.

Almost all motherboards these days have a USB header. Due to size and cost restraints many motherboards only have 2 USB ports on their back panel, but often they can actually support more then 2 USB ports. They will typically support additional ports via the use of a USB header. A USB header is either a single or double row of header pins on the motherboard that can be used to add additional USB ports to a computer via the use of an appropriate set of header connectors, wires, and a USB port. Each pin on the header corresponds to a wire inside a USB cable. These pins must be clearly marked so that you can hook them up to the wiring correctly. There are 2 common layouts for a USB header.

Intel Standard USB header Layout: (used by over 90% of motherboards)

instusb1a.jpg

Gigabyte Style USB header Layout: (used most commonly on Gigabyte brand motherboards)

instusb2b

Now that we know the types of headers we have to take a moment to understand the USB wiring. Understanding the wires First off: All USB cables have 5 wires. 4 of these wires are actively used. Here's a reference from the official USB standard.

instusb3

On a front mounted USB port you'll have either the first 4 wires connected to properly colored wires (red for power, white/orange d-, green/yellow d+, black for ground) or all five wires attached to the port (same as the former, but one extra black wire). Now where it gets tricky is how to attach each of those wires to corresponding pins on the motherboard.

The wires are "tailed" (attached to a header connector) using any one of a number of different types of connectors. Below you'll find a list of the common ones.

Common USB case header connectors 4 joined pins + 1 extra ground.
usbheader

Compatibility: Compatible with both header arrangements because of the extra ground. May not work with some odd arrangements To hook up carefully match each pin. For the Intel hookup you'll have the extra ground wire not attached to anything. For the Gigabyte hookup you'll have the extra ground hooked to ground pin on the motherboard, and the standard ground jumper will be over the missing pin on the header.

All pins separated

instusb6

Compatibility: Compatible with every header. If all the pins are separated the only real issue is lining up the pins with the appropriate places on your header. It should be compatible with all headers. Just make sure you read the writing on each individual connector. Please check the troubleshooting info at the end of the article for important information on this configuration

Power and Ground separate, d-, d+ joined Lian-Li style

Compatibility: Compatible with all common headers. This sort of arrangement is common to almost all Lian-Li cases. Make sure that you get the wires connected to your header in the proper order. If you find that the port does not function the most common cause is accidental reverse of the d-,d+. Try switching it.

All pins joined Intel style easy connector

making the Connection Once you know what type of header you have, and what type of connector you have on the wiring, you need to connect the two of them. In order to do this, you must first figure out what pin goes with what part of the connector. To do this, you should first consult your motherboard manual. Below you'll find an excerpt from a fairly recent motherboard manual for the Asus A7M266 motherboard. It's typical of a motherboard manual for a board using the Intel standard USB header.

instusb5

The first thing you'll probably notice is that the wiring from your case and the names of the pins might not quite match up name wise. This is a common problem. Motherboard makers and case makers really haven't decided on what to call each pin. Here's a rough list of names.

Power may be called: P, VCC, USB Power, Power, and PUSB. On wiring it's always red. Ground may be called: G, GND, Ground, and GUSB. D- may be called: USB-, USBP-, D-, or just -. D+ may be called: USB+, USBP+, D+, or just +.

To complicate things a bit more you'll probably notice that there's a number before each one. Take a look at the picture above from the USB hookup diagram for the A7M266.

You'll see that Asus decided to number the middle pins. On the first row (starting with pin 1, and marked with a 1) you'll find that they list D- as USBP2-, and D+ as USBP2+. The number 2 tells you a few things. First off: It's the 3rd USB port on the motherboard (they started numbering at 0), second it tells you that that D- and D+ must be used for the same port. Case manufacturers are just as likely to number their ports differently.

Take a look once again at the 4-pin joined picture: usbheader

Notice that you're D-'s have either a 1 or a 2 on them. These also tell you that they are part of the same USB port. (Remember, 1 port has 4 required wires). The numbering on the connector and the numbering on the header doesn't have to match.

To connect everything grab the following connectors: a same number D pair, (D-, D+), 1 power, and one ground. If your power and ground are numbered make sure all 4 are the same number.

Tip: Most cases that use all separated pins will bundle these together for you to make it easier.

Now, take your Power, D-, D+, and Ground and line the connector up with the appropriate 4 header pins on your motherboard. The header pins will be in a row under the Intel style, and in the Gigabyte style it will either be a row of 1 pin, a gap, and then 3 pins, or 3 pins, a gap, and then 1 pin. Press the connector down over the header pin and make sure it's firmly attached. Once you have done this go back and grab another set of connector wires (Power, D-, D+, Ground), and hook up your second front USB port. If your case has more then 2 front USB ports, and your motherboard has more then one front USB headers, then repeat the above as necessary.

Example: If you were hooking up the front USB on a A7M266, on a case with the pictured 4-pin joined connector type then: VCC lines up with USB Power, USBP2- lines up with USB1-, USBP2+ lines up with USB1+, and GND lines up with GND. For port 2, VCC lines up with USB Power, USBP3- lines up with USB2-, USBP3+ lines up with USB2+, and GND lines up with GND.

I would like an internal view of eMachine T4150 to be sure everything is connected correctly


I could not find an internal photo with everything connected but I could find a picture of the motherboard but it was very small. Just make sure your graphics card is inserted fully into AGP slot, processor is clipped down, memory is clipped down, and your hard drives are on one IDE ribbon cable and your rom drives are on the secondary IDE channel. (jumpers are correctly set to Master/Slave). Then make sure the CMOS jumper is set correctly and check the button cell battery for the CMOS clock. That's it
