    Hi, thank you for the information. The pics were on spot and the schematics were great backstop in case I have to go native on this thing. Good idea getting adapter for parts. Imagine I heard back from multiple people on the web before I heard back from the vendor that sold me the unit without the ability to plug it in. Go figure. Thumbs up regards einstein91344

I've supported these at HP, strange animal. I think the 42 was the fast one with a P4. There's a block adapter for these I beleive. You would be better off to verify the part number and find one on eBay. Or a complete unit for parts.

Wiring scematic for a gateway gt5636e


Gateway Support > GT5636e Desktop PC > Main Support page,

http://support.gateway.com/us/en/s/PC/R/1014825R/1014825Rnv.shtml

Click on Components in the list.

Scroll down.
Under the black - Motherboards - subheading click on the blue -
4006245R - Intel (Stoughton) G965 motherboard with LPT port

In the list click on the blue - Product Views

B - Processor Core Power Connector
That is to the LEFT of the processor socket.

This is a general example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Note the LOCK clip on the power cable's connector, and the matching TAB, on the motherboard connector.
When the power cable is deemed to be plugged in Tightly, and Correctly; the Lock clip will be hooked over the Tab.

The 24-pin ATX main power cable's connector, and matching motherboard connector; has this feature also.

D - CPU Fan Connector
Go straight up, from the processor socket to the edge of the motherboard, then to the Right.

Notice how the motherboard connector is Keyed, and the matching plug connector that goes to it.
Same thing for all those white 3-pin connectors, on the motherboard.

[CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Does NOT mean Personal Computer ]

G - Floppy Disk Drive Connector
Black 34-pin connector for a Floppy Drive.
It is next to the White 24-pin ATX main power cable connector.
Right side of motherboard, towards the Top.

If I were a betting man, I would bet you aren't using it. No Floppy Disk Drive.
But I'll tell you what.........it's nice to have.
A Floppy Disk Drive doesn't take squat to run.

Need to flash the BIOS after the BIOS has been corrupted, you can use a Floppy Disk/s with the BIOS upgrade info on it.
Jus sayin'.

H - ATX Power Connector = 24-pin ATX main power cable connector.
This is a general example of a 24-pin ATX power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

NOTE* Color of connector does NOT matter ]

Location covered above. Right upper side of motherboard

I - Rear Chassis Fan Connector

With the huge(?) image of the motherboard on Gateway Support, and the equally sized images available on the internet; you're on your own.

Easy to find though. Small white 3-pin connector, with Rear Fan printed next to it. I'm betting to the Left, of the aluminum finned Heatsink, for the Northbridge chip. (Below processor socket)

Next to an Electrolytic Capacitor, that has a gold, and black plastic sleeve.
Used for a computer case fan in the Rear. Draws air OUT of the computer case. (Out the back)

J - PCI Express x16 Connector.
THIS, is where the graphics card goes.
A PCI Express graphics card.

OR, you can use a PCI graphics card, in one of the white PCI slots.
I would NOT. The PCI technology is NO where near, the PCI Express technology,

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


The front of your computer is the Front Panel.
L - Front Panel Audio Connector, is for the audio ports in the Front Panel.
FP_AUDIO

It is to the Left of the white PCI slots, and the header itself is Yellow in color.
Do not know the individual pinout of this Front Panel Audio header.

You have a plug connector that plugs onto it.
You can see the header is missing one pin. The missing pin is called the Key.
This shows you how to line up the plug connector to it.

If you need the individual pinout, trace the individual wires to the Front Panel audio ports.

N - HD Audio Link Connector
Plug connector goes on it also.
Location believed to be Bottom edge of motherboard, towards the Left.

O - Parallel ATA IDE Connector
Just the usual 40-pin IDE (PATA) connector.
(Actually, ONLY 39 pins )
Bottom edge of motherboard, black in color

ALL three harddrive options are SATA, so you won't be using it for your harddrive.
The optical drive you have is IDE (PATA), so this connector is where it plugs in.

Notice the cutout in the side of the connector. This is a Locating Notch.
Lines up with a Locating Lug, on the flat IDE ribbon cable, for the optical drive,



P - IEEE 1394 Connector
It's for the Firewire (1394a) ports in the Front Panel.
Plug connector goes to it.
Color is Blue, and it is in-between the white PCI slots

Q - USB 2.0 Connectors
Two of them side by side, but separated by a small Electrolytic Capacitor.
Black color for these USB headers.

They are for the Front Panel.
Location to the right of the black IEEE 1394 connector, bottom edge of motherboard.
They utilize the USB 2.0 technology.

ONLY one is marked. -> USB 2.
It has FP_USB_2, printed under it.
Front Panel USB 2.
The other one to the Left, is FP_USB_1.

EACH of those headers supports TWO USB ports.

A (Media) Card Reader has TWO cables, and uses ONE USB header.

One of those USB headers then, can be used for a Card Reader in the Front Panel.
The other USB header for Two USB ports in the Front Panel.

R - SATA Connectors
You see there are SIX.
Marking starts with SATA 0. (SATA0)

SATA 0 is for the SATA harddrive.
SATA 1 is for an optical drive (CD/DVD drive)

IF, you are using TWO optical drives, the MAIN optical drive connects to SATA1. The secondary optical drive connects to SATA2.

Make sure if you are adding a SATA optical drive, (That the computer did NOT come with), that you go into BIOS Setup; and ENABLE that SATA connector you wish to use.

HOWEVER,............the beauty of SATA is, that you can plug ANY device into ANY SATA connector; and BIOS will find the device.

Want to plug an optical drive into SATA0? No problem.
Want to plug the SATA harddrive into SATA 5?
No problem.

Just make SURE that SATA 5 is ENABLED, in BIOS Setup.

S - Front Panel Connector

Again, the front of your computer is the Front Panel.
Moving on.......
The area of contact pins on the motherboard, that the Main wires from the Front Panel connect to, is the Front Panel header.

Here you can see the individual pins, are marked by colors on the header itself.
Pin 2 is next to the Green pin, on the Bottom row to the Right.

Pin 1 is above it.
Looks confusing, because Pin 6 for the header above it, is marked right there also.

Pin 8 is marked on the bottom of the header.
Pin 9 is marked on the Top of the header, all the way to the left; except some 'crackhead' marked it upside down. (lol)

So,........pinout..........

Starting on the Top row, at the Right side; going towards the Left,
Pins 1, 3, 5, 7, and 9.

Starting on the Bottom row, at the Right side; going towards the Left.
Pins 2, 4, 6, and 8. There is NO Pin 10.

1) Pins 1 and 3 are for the HarDDrive activity LED.
(Light Emitting Diode, so I'm not going to refer to it as a light.
It is. LED states that)

Pin 1 is for the Positive ( + ) connection.
If the HDD LED is dim when the harddrive is active, switch the wires around.

2) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

3) Pin 9 is 5 Volts.
5 Volt power. That is why it is marked as +5 Volts.
Used for the factory to test with.
It is N/C. Not Connected.

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

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

6) Again, there is NO Pin 10.

T - Auxillary Front Panel Power On LED Connector
Right above the Front Panel header.

Freaking beats me why it would even be on there.
To iterate;

There are only 2 pins. This type of Power On LED header has 3-pins usually.
It is used for a dual color Power On LED.

Used back in the day when computers had the 'Turbo Mode' feature, and 'Normal Mode' feature.
Dual colors of dual color Power On LED was usually Green, and Yellow.
Green for Turbo Mode, Yellow for Normal Mode.

Was in reality a bunch of cr@p.
Turbo Mode was the computer actually operating in NORMAL mode, while Normal Mode was the computer was operating slower.
Just another gimmick.

{'Buy me! I'm a shinier Red bike! }

Probably why Gateway states it does Not support this feature.

U - Clear CMOS Jumper
If you do not know what this is for, LEAVE IT ALONE.
(He states politely)

V - Front Fan Connector
Yes, you guessed it. For the computer case fan in the Front, that draws air INTO the computer.
Location? Close to the round CMOS watch type battery.

X - Intrusion Switch Connector

Can't believe they are still using this cr@p.
It's so if someone opens the computer case, the power to the motherboard is turned off.

Good feature, but if the person working on the computer; doesn't know enough to unplug the computer from power FIRST, then chances are they do Not know about Anti-Static Procedures either.

Don't FOLLOW Anti-Static Procedures, you can use the motherboard for a Frisbee, or expensive paperweight.

Static shock the motherboard, is why.
Goodbye Processor (CPU), Ram Memory, motherboard, graphics card, (IF used)......and who knows what else.

DO NOT connect anything to it. Leave alone.

(If you do though, it has to be ENABLED in BIOS Setup; to use this feature)

What's your problem? I need a schematic for my HP Pavilion slimline


http://h10025.www1.hp.com/ewfrf/wc/product?product=3688725&lc=en&cc=us&dlc=en&lang=en&cc=us

Ready for a long read?

A) Power Supply /Motherboard

Motherboard with no hardware components installed, nor cables attached,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01321559&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3688725

I also would like you to scroll down a little further, and click on the + sign to the left of - Motherboard layout.
Shows an illustration of the motherboard.

1) 24-pin ATX main power cable:
Looking at the motherboard illustration (Motherboard layout), look at the Top/Middle.
ATXPWR1 is where the 24-pin ATX main power cable plugs in.

In the photo you see - ATXPOWER and CPU_FAN above this black connector.

[ Processor fan {CPU Fan}, is the first white 4-pin connector, to the right of the black 24-pin ATX main power cable connector.

A Chassis, {Computer case} fan plugs into the next 3-pin brown header to the right.
That was the only space the motherboard manufacturer had, to mark the motherboard for those two connectors ]

This shows a general example of this type of power cable.
(Note color does NOT matter),

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Note the Lock on the side (Middle) of this power cable's connector.
Also note the matching Tab on the motherboard connector.

The Lock operates like a see-saw on a playground. The top is squeezed in to bring the hooked end of the Lock, away from the Tab on the motherboard connector.
When this power cable is deemed to be plugged in properly, and tightly, the Lock's hooked end will be over the Tab.

That concludes the power cables coming from the Power Supply, to the motherboard.

B) Power Supply / Peripherals:

The Harddrive is a SATA unit. 500GigaByte, and has a 7200 RPM spindle speed.
There is a SATA power cable that plugs into it.
General example of a SATA power cable,

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

Note that a SATA power cable has 15 contact pins. It is the longer of the connectors when comparing to a SATA data cable connector.
(7 pins)

The optical drive (CD/DVD burner that has LightScribe technology), is a SATA unit also. Uses a SATA power cable.

A) Data Cables:
The Harddrive, and optical drive require a SATA data cable.
General example of a SATA data cable, and SATA data connector on the motherboard,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the SATA connector on the SATA data cable.
Has an L-shape on the inside. Lines up with the L shape on the motherboard connector, and Harddrive and optical drive connector.

The red connector shown is a SATA data cable connector, on the motherboard.
Looking back at the HP Support page, look at the illustration.
(Motherboard layout)

The Ram Memory slots are designated by XMM1 and XMM2.
To the bottom left of them are the two SATA data connectors.
SATA 1 and SATA 2.

In the motherboard photo you can see they are plainly marked.
SATA 1 is White, SATA 2 is Black.
The Harddrive plugs into SATA 1.
An optical drive will plug into SATA 2.

Most of the time a SATA data cable will have a 90 degree bent elbow, for plugging into the Harddrive, and Optical Drive.
The straight connector end plugs into the motherboard.

A) Processor Fan and Chassis Fan:
I have already stated where the processor fan plugs in, and the Chassis (Computer case) fan plugs in.

A) USB Front Panel:
The Front Panel is the front of your computer. The USB headers on the motherboard, USB1 and USB4, are where the front USB ports plug into.
These headers (Connectors) are to the right of the SATA data connectors. (F_USB1 and F_USB4)

A) Front Audio:

The long Black slot at the bottom of the motherboard, is a PCI-Express x16 slot. Used for a graphics card.
To the left of it is the Front Panel audio connector.
F_AUDIO1, and is Yellow in color.

A) Front Panel header:

As stated the front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires go to, is the Front panel header.

On the motherboard illustration it is at the Bottom/Right, and marked as F_PANEL1

Horizontal header, and two rows of contact pins.
4 on the Top row, and 5 on the Bottom row.

IF, I have this pinout correct;

Pins on the Top row are number EVEN.
Pins on the bottom row are numbered ODD.

Starting on the LEFT side coming towards the Right, Top row;
Pins 2, 4, 6, and 8. There is No Pin 10.

Starting on the LEFT side coming towards the Right, 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 HDD LED is dim when the Harddrive is active, switch the wires around.

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

C) Pin 9 is N/C. Not Connected. (It's a 5 Volt power wire used for factory testing )

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

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

F) There is No Pin 10.

Hopefully you just have a cable with a connector on the end, that plugs into the Front Panel header.
Same with your Front Panel USB ports, and Front Panel audio ports.

After you have hooked up all cables, and deem to be finished, take the Ram Memory module/s ('Stick') out, and reinstall.
Most of the time they get bumped loose, and you CANNOT see by a visual inspection if they are.

Best method is to just remove them/it, and reinstall. This way you are ASSURED they are seated, and tight.

I Hope you have been FOLLOWING Anti-Static Precautions.
If not plan on using your motherboard, Processor, Ram Memory, Graphics card(?), and harddrive, for an expensive paperweight.

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.

Relieve your body of Static electricity BEFORE reaching inside your unplugged from power computer, or removing any new parts out of their anti-static bags, or cartons.

Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal framework of the open computer case.
This action will relieve your body of Static.

IF you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.

For additional questions please post in a Comment.

Wiring diagram for northgate computer


You didn't state the model number, unless that is it in the problem heading, STAX2517C2.

IF, this is the Model Number of the Northgate Desktop PC, it is supposed to come with a Foxconn/Winfast K7S741MG-6L motherboard,

http://www.ebay.com/itm/STAX2517C2-Winfast-Foxconn-AMD-Motherboard-K7S741MG-6L-/380384605182

Click on the photo with SOLD across it. On the next page scroll it down.
There is a main view shown, and separate views under it.
In the separate views, click on the third one from the Left.

http://www.motherboards.org/imageview.html?i=/images/mobot/motherboards/8286.jpg

Looks like the Front Panel header on the motherboard, is an 9-pin unit.
(Down by the round CMOS battery, black plastic rectangular header, 9-pins.
In the photo it is down to the Bottom/left corner )

[ The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.

May be an abbreviation silk-screened on the motherboard next to it.
F PANEL 1, or FRP1, or FP1 ]

Motherboard sitting in your computer case, the Front Panel header is sitting Horizontal, and parallel to the bottom edge of the motherboard.
There are two rows of pins.

4 across the Top row; 5 across the Bottom row.

The best method is to take an LED light with two wires, and touch two contact pins at a time.
I would go across the Top row first.

Start with the first two pins. Then the second two pins.
When you touch the correct two pins, the Power Supply will come on.
(So will the computer)

You now know that this is the two pins for the Power On switch.
Computer running do not touch the two pins again.
Now touch two other pins.

When the LED light blinks, you know you have the HarDDrive activity LED pins.
If the LED stays on you have the Power On LED pins.

If the computer restarts you know you have the Restart switch pins.

This is what I have that seems to be close, for a Front Panel header pinout for your motherboard.

HOWEVER, I would like you to connect the two pins to the Power On switch first. Just those two.
If these are correct there is a 99 percent chance the others are too.

A) Using an LED light will not harm your motherboard. If the computer isn't running, (Power Supply not on), then you will not be touching any 'live' pins on the motherboard.

Just make a brief contact, with the wires to each set of 2 pins. The Power On switch is a Momentary Contact Switch.

Pinout I have;

Looking at the Front Panel header - Top row;
Starting at the Left side, coming across to the Right side;
Pins 2, 4, 6, and 8. Blank spot -> No pin.

Bottom row;
Starting on the Left side, coming across to the Right side;
Pins 1, 3, 5, 7, and 9.

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

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

C) No pin 10. Blank spot.

D) Pins 1 and 3 are for the HarDDrive activity LED (Light)
Pin 1 is for the Positive ( + ) wire.
If the HDD LED is dim when the harddrive is active, switch the wires around.

E) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

F) Pin 9 is N/C. Not Connected. Probably 5 Volts (DC), and reserved for the factory.

Would appreciate hearing back if this pinout worked for your motherboard.
Also would appreciate if it did not work, and you found out, how about posting back on that also?
A LOT of people would appreciate this information.

How do i hook up usb button in intel 845 motherboard


Well, that's a start. You know you have an Intel motherboard in your eMachines, that uses an Intel 845 motherboard chipset.

It is an Intel D845GVSR motherboard.

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

Left-click on the blue -
Intel Desktop Board D845GVSR Product Guide (PDF)

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
(I would advise upgrading to Adobe Reader X { 10 }, however, if you don't have it )

After you click on the above link, it may take up to 30 seconds before the first page comes up. (Took 6 seconds just now. Adobe Reader X, and medium speed DSL connection)

At the top of the PDF file, is the PDF file page number box.
It is to the left of the Down Arrow.
Go to Page 11.
T is the Front Panel USB header.

This is where the USB ports on the front of the computer, (Front Panel) connect to.

Go to Page 31.
E is the Front Panel USB header.
The Front Panel USB header is J9F2.

Observe the numbers next to the pins.
Go to Page 33.
This is the pinout for the Front Panel USB header, using those contact pin numbers.

1, 3, 5, 7, and 9 = one USB port
2, 4, 6, 8, and 10 = one USB port

Notice pins 9 and 10 are not used.

You can connect two USB ports to this header.

The pinout of ANY USB connector, female, or male, is set to a Standard.

This is the standard pinout for USB connectors,

http://pinouts.ru/Slots/USB_pinout.shtml

In case you cannot download the Intel D845GVSR motherboard manual;

Looking at the motherboard in it's normal position, installed into the computer case, the USB header is on the Bottom edge of the motherboard.

It is to the immediate Right, of the bottom white PCI slot (PCI 3)
It is to the Left of the motherboard mounting hole.
It is Below the Intel 82801DB, Southbridge chip.

Two rows of pins.
5 across the Top row, 4 across the Bottom row.

STARTING on the Left side, (Towards the white PCI slot), and going towards the Right, the pins on Top are numbered,
Pins 2, 4, 6, 8, and 10

STARTING on the Left side, (Towards the white PCI slot), and going towards the Right, the pins on Bottom are numbered,
Pins 1, 3, 5, and 7

Pins 1, 3, 5, and 7 = One USB connection
Pins 2, 4, 6, and 8 = One USB connection

Pin 9, and Pin 10 are Not used. (N/C. No Connection)

A) Pin 1 is for Power

B) Pin 3 is for D-
The Data, or Signal wire. It is the Negative connection

C) Pin 5 is for D+
The other Data, or Signal wire. It is the Positive connection

D) Pin 7 is for Ground

Going to the other USB header;
A) Pin 2 is for Power

B) Pin 4 is for D-

C) Pin 6 is for D+

D) Pin 8 is for Ground

For additional questions please post in a Comment.

Out of curiosity which eMachines is this?

My power led connector (green,white) power sw connector (black,white) got out of place and i dont where they go


The eMachines T3302 desktop computer, uses an FIC K8M-800M motherboard.
(First international Computer, Inc.)

Where those wires go on the motherboard, is termed a Front panel header.

The Front Panel is the plastic front bezel of your computer.
(Where the Power On button is, Power On LED light, and so on)

Looking at the motherboard with the Processor to the Top, Ram Memory slots to the Right, the Front Panel header is at the bottom right corner, and over to the left.

Look at the jumper block in the bottom right corner. Right in the corner.
This is the LED type selector, jumper block.
Has 6 pins.
3 across the Top, 3 across the Bottom.

(This jumper block is to set whether you are using a Power On LED light, that has Dual Colors, or a Single color.
The default setting of the jumper on the block, is set to use a Dual Color LED light, for the Power On LED)

Move to the left of this jumper block. The Front Panel header is to the left of this jumper block.

(FIC terms it a Front Panel Block Connector)

It should be White in color.
Is right against the bottom edge of the motherboard. (Parallel to the outside edge of the motherboard)

Has two rows of pins sticking up.
5 across the Top.
4 across the Bottom.

The pins are numbered from the Right, going towards the Left.

(From the Power On LED jumper block, towards the Front Panel header)

On the Top row going from Right, towards the Left,
Pins 1 ,3, 5, 7, and 9.

On the Bottom row going from the Right, towards the Left,
Pins 2, 4, 6, and 8.

A) Pins 1 and 3 are for the Power On LED light.
Pin 1 is for the Positive ( + ) wire.
(Green)

B) Pins 5 and 7 are for the Power On switch.
Pin 5 is for the Positive ( + ) wire.
(Black)

[Although it really doesn't matter which way the wires go. It's a SWITCH]

C) Pins 2 and 4 are for the HarDDrive activity LED.
Pin 2 is for the Positive wire ( + )

D) Pins 6 and 8 are for the Reset switch.
(IF used)

If any of your LED lights are dim, after attaching the Positive wire for each LED, it's because the Positive wire is on the wrong pin.
Switch the wires around

Which connectors are used for front panel, power on (red @white) and led ( blue @ white) please show a close-up view


Hi,
On the motherboard the pinouts on the front panel should be colour coded, and marked with letters like in this picture >>>>>
ce10baf.jpg

The connectors are also marked corresponding to where the connect on the motherboard, like in this picture >>>>>>
66ce2fc.jpg

If the board is not colour coded then the motherboard will marked with the same letters, you may need a strong light to see the marks.

Regards.
