Wiring diagram for front panel on a Gateway 507 GR pentium 4 computer, the 3 plugs accidently came undone while replacing the power supply.

The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the main wires of the Front Panel go to; is the Front Panel header.

JFP1 is Junction Front Panel 1.
Better method IMHO is to state as Front Panel - Junction 1, so it's easier to understand.

Just some 'trivia' that I thought I would post to you.

Would however like to post;

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 BEFORE reaching inside your computer.

(The Static? More than likely you won't see it, or feel it.
Your computer will,.....POOF! )

Computer ON a table, computer Unplugged from power, computer case open;
TOUCH an unpainted surface of the metal frame 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 case upon your return.

Since I'm here;

The method to test if the problem is the Power On switch, or the Power Supply; is to use a jumper wire on the 24-pin ATX main power wire's connector,

http://support.gateway.com/s/MOTHERBD/FIC/105552/105552mvr6.shtml

This is an example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

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

A jumper wire is used to BRIEFLY connect the Green wire, to ANY Black wire.
The Green wire is the Soft Power On wire. Abbreviated as PS_ON.

ANY Black wire you see is a Ground wire.
(And that goes for ANYWHERE in the computer)

The preferred jumper wire is a straightened out paperclip.
It is bent into a U-shape. Turn it upside down, and that is how it's used.
The top is wrapped a few times with black plastic electrical tape.
This taped area is for your fingers, and thumb to hold onto.
The 'legs' that come down on each side, are what is used.

One leg slides down, into the back of the ATX main power cable's connector, into the socket hole with the Green wire in it.
[The BACK of the connector is where the wires go in ]

Slides down RIGHT NEXT TO the green insulation of the wire, and goes down in far enough, to touch a female metal terminal.

All wires going into the 24-pin ATX main power cable's connector, end in this style of female metal terminal,

http://www.mcmelectronics.com/product/28-9420&utm_medium=Affiliate&ref=cj&utm_campaign=CommissionJunction&utm_source=CommissionJunction

Looking at the middle photo of the Playtool link, you can barely see the openings of the female metal terminal connectors.
They look like small brass rings.

The other 'leg' of the U-shaped jumper wire, goes down into a socket hole, with ANY Black wire in it.

24-pin ATX main power cable is plugged in, just like the photo to the Right, in the Playtool link.
Power Supply plugged into power.

U-shaped jumper wire is used Briefly. No more than 2 seconds.
(1001..1002)
[The Power On Switch is a Momentary Contact Switch ]

What is the Voltage involved in the Soft Power On circuit?
5 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.

Just want you to know, so you won't think I could lead you into being Shocked.
Not saying there won't be a small spark, though.
You may wish to wear a glove on the 'jumper wire hand'.

IF the Power Supply comes on, you have a bad Power On switch.
(You noticed before that, but this would have led you right to it)

IF the Power Supply does NOT come on, you have a bad Power Supply.

Going further;
The Power Supply in your computer is an SMPS.
Switched-Mode Power Supply,

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Another widely used term for Power Supply is the abbreviation
PSU. Power Supply Unit.

It converts the dangerous high AC voltage, 100 to 240 Volts, from your home or business; into 3 low DC Voltages.
The dangerous voltage is contained IN the metal case of the Power Supply.

The 3 low DC Voltages are;
A) 3.3 Volts DC
B) 5 Volts DC
C) 12 Volts DC

Let's take -> Q - Front Panel Connector, for an example,

http://support.gateway.com/s/MOTHERBD/FIC/105552/105552mvr18.shtml

Now you can see where every wire goes on the Front Panel header,
JFP1.

I don't know the color code of the twisted wires, that come from the Front Panel.
If -> I had to trace them, I would remove the Front Panel, and trace them to the;
A) Power On switch (PWR SW, or simply SW)
B) Power On LED (Light) (PWR LED)
C) Reset switch, (IF used) (RST SW)
,and,
D) HarDDrive activity LED (Light) (HDD LED)

If I were a betting man, I would bet the Red and White twisted pair of wires went to Pins 6 and 8. Power On switch.

Blue and White twisted pair of wires to the Power On LED. (Light)
Pins 2 and 4.

[I know. There's 5 minutes of your life you'll never get back.
I just posted the above, in case you run into this problem someday, and it isn't a loose Front Panel wire ]

Rut Ro!

!O_O!

1) Three 'ribbon' cables are all you need.
Two IDE 40-pin cables, and One 34-pin Floppy Drive cable.

The wider 40-pin IDE ribbon cables are for the Harddrive, and Optical Drive/s. (CD/DVD drives)
(Actually 40 -> socket holes, and actually only 39 are used)

The narrower 34-pin IDE ribbon cable is for the Floppy drive.

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

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

Note*
I would like you to look at a Locating Lug, on an IDE flat ribbon cable, (IDE is also referred to as PATA),

http://en.wikipedia.org/wiki/File:PATA-cable.jpg

Note on the blue rectangular connector, the two ridges at the Top/Middle. This is a Locating Lug. Shapes vary, but the same basic principle is kept.

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

Note the two IDE motherboard connectors. One Blue, one Black.
Note on the blue IDE connector that there is a cutout on one side.
(Outside edge of motherboard, Middle of side )
This is what the Locating Lug lines up with.

[Note also that IDE1 is silkscreened, on the outside edge of the motherboard, and between the blue IDE connector.
This is where the harddrive cable plugs into.

IDE2 which is right above (Black), is where the optical drive/s cable plugs into ]

IF, there is No Locating Lug on the flat IDE ribbon cable's connector;

The thin Red stripe on the side of the flat ribbon cable, denotes which side Number 1 wire is on.

Looking at your motherboard, with the Processor to the Top, and Ram Memory slots to the Right; Number 1 pin in the two IDE connectors on the motherboard, is on the BOTTOM.

The Red strip on the flat ribbon cable, goes towards the Bottom of the motherboard.

Looking at the back of your IDE harddrive, start at the Right side, go towards the Left;
On the right side are 4 pins. These are for the power cable. To the left of them are jumper pins. To the left of the jumper pins is where the flat ribbon cable plugs in.

The Red strip ALWAYS goes toward the power cable.
Same thing with an optical drive.

http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&_trksid=p4340.l2557&item=320584071749&nma=true&rt=nc&si=3aRaG4yZHczJd6Q3wXW2IIvaBys%253D&orig_cvip=true&rt=nc

With the above Gateway E-4000 motherboard example, the IDE connectors for the Harddrive, and optical drive/s, is at the Top/Middle.
The White connector is for the Optical Drive/s cable. (IDE2)
The Black connector above it is for the Harddrive cable. (IDE1)

The smaller black connector to the Left of the black Harddrive connector, is for the Floppy Drive cable.
The whitish opaque long connector under the black Floppy Drive connector, is where the 20-pin ATX main power cable plugs into,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

(Note color of connectors does Not matter)

3) Where the black Processor Fan is. Come to the Bottom/Right corner of it. Go straight across, and stop under the aluminum finned Heatsink, above it. (Heatsink looks like a meat tenderizer)

This whitish square 4-socket hole connector on the motherboard,
is where a 4-pin ATX +12 Volt power cable plugs in,

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

Note that both it, and the 20-pin ATX main power cable's connector, has a Lock on one side. This lines up with a Lock Tab on the motherboard connector. When the power cables are deemed to be tightly, and properly plugged in, the hooked end of the Lock will be over the Lock Tab.

This type of power cable plugs into the Harddrive, and Optical Drive/s,

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

(Commonly misnomered as a 'Molex' power cable. Molex was the first company to make the connector, and their manufacturer name stuck. Kind of like referring to an open-end wrench as a Crescent wrench)

4-pin Peripheral power cables may also be used for computer case fans.
(Yellow wires are 12 Volt wires. { DC }
Red wires are 5 Volt wires. { DC }
Black wires are Ground wires.
Do not hook up a 5 Volt fan to a 12 Volt wire )

Intel D845GRG motherboard is Gateway part number 4000828,

http://support.gateway.com/s/MOTHERBD/INTEL/2519530/2519530mv.shtml

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

In the list click on Q - Front Panel connector
Motherboard installed in computer case the Front Panel is down in the Bottom/Right corner. It is the second header over from the Right.

The pins across the Top row are numbered EVEN.
Starting on the LEFT side going towards the Right;
Pins 2, 4, 6, 8, 10, 12, 14, and 16.

The pins across the Bottom row are numbered ODD.
Starting on the LEFT side going across to the Right;
Pins 1, 3, 5, 7, 9, 11, 13, and 15.

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, 11, 13, and 15 are not used. Reserved for the factory.

D) Pins 2 and 4 are for the 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
There is No Pin 14
Pins 12 and 16 are N/C. Not Connected.

You can also see in the list where the Front Panel USB ports connect to (P - Front Panel USB connector), and the Front Panel Audio ports, (V - Front Panel Audio jumper )

The Power Supply used is a piece of Cr@p.
160 Watts. This is what it looked like,

http://www.ebay.com/itm/Gateway-E-3600-4000-Power-Supply-6500582-NPS-160CB-Test-/270707982390?pt=LH_DefaultDomain_0&hash=item3f07740036

Gateway part number 6500704,

http://support.gateway.com/s/POWER/6500704/6500704nv.shtml

(Click on Product View, and on Specifications)

It is approximately 6 Inches Wide, 3-1/2 Inches Tall, and 4-1/2 Inches Long.

When installed there is a green plastic lock, that swings over to lock the Power Supply in.
I would remove that green plastic lock mechanism, and use an ATX Power Supply.

All the same dimensions as above, except it is 5-1/2 inches Long.
ATX power supplies are used in a LOT of desktop computer, and readily available. A VERY common Power Supply.

Guess what else? You won't be stuck with a lowly 160 Watt power supply, or have to pay through the nose to get another piece of junk like it.

The Philips head screws in the back of the computer case, hold the Power Supply in just fine, without that plastic piece of junk, also.
An example of a Power Supply that would work, green plastic Lock removed,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1389575&CatId=1078

430 Watt Power Supply will Not harm the computer.
Why?
Because a computer ONLY uses the power it needs, and NO more.

As for the orange SATA headers on the motherboard. The SATA harddrive should plug into the lowest number of SATA header.
It may be labled SATA 0, or SATA 1.

The beauty of SATA however, is that you can plug the harddrive into anyone of those SATA headers. BIOS will find the device. (Harddrive)

(P.S., I took you the 'Long Way', so that you can have other information about your computer, at your fingertips )

Here is the manual for your motherboard (since describing a diagram probably isn't very useful...)
http://dlcdnet.asus.com/pub/ASUS/mb/socket939/A8N-SLI/e2024_a8n-sli.pdf

You want to look at pages 27-35, they describe what you need to plug into the motherboard. Basically make sure you have connected:

1) 24-pin power cable (from power supply)
2) 4-pin power cable (for CPU from power supply)
3) Any case fans with 3/4 pin connectors.
3) hard drives (SATA or IDE)
4) USB front panel ports
5) Audio front panel ports
6) Case plugs (power LED, hdd LED, power switch, and reset switch).

Have you tried a different power-supply?
A power-supply must emit a few different voltages; if it fails to output one of those voltages, the fans still may spin, and the CD-drive-tray may still open, but the motherboard may not be getting the correct voltages.

Disconnect the AC power, and then open the case. Look at the capacitors (those black/silver cylinders with an X in their silver-coloured top).
Any capacitor that is bulging, i.e., does NOT have a perfectly-flat top, is leaking. Any capacitor that seems to have rusty-brown "sand" on top also is leaking. Either way, it's time to replace the motherboard.

The Power Supply in the computer is bad. This is no big deal. You can replace it.

This is Gateway Support, and the main page for the Gateway 505GR Desktop PC,

http://support.gateway.com/s/PC/R/4054/4054nv.shtml

Left-click on Components.

Scroll down to the heading Power Supplies.

Left-click on - 102015 - 300 watt power supply.

It's just a common ATX style power supply, that is found in over 90 percent of personal computers. Readily available everywhere.

This is an example of an affordable replacement. It is not advertising for said website, nor power supply manufacturer.

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3255391&CatId=1078

What you need to look for in a replacement power supply for your computer.

1) Reliability
2) Correct power cables
3) Correct amount of power cables
4) Correct form factor. (Size of power supply case, and shape of case, in this instance)

2) & 3)
You need the following power cables, and these amounts.

A) (1) 24-pin ATX main power cable
[Main power cable to motherboard]

B) (2) 4-pin Peripheral power cables
[Power for the two optical drives]

C) (1) 4-pin ATX +12 Volt power cable
[Connects to the motherboard.
Power for the Pentium 4 processor]

D) (1) SATA power cable
[Power for the SATA harddrive]

The above power supply in the link has the correct power cables, and more than the correct amount.

Scrolling down the page you will come to the heading - Detailed Features
Here you will see,
A) 20 + 4 pin The two power cables are used together, to equal a 24-pin main power cable

B) 8-pin. Not needed in your case, unless you wish to install a graphics card that uses this power cable.
Just tie this cable up out of the way.

[You do have a PCI-Express x16 slot on the motherboard, which can be used for a PCI-Express graphics card]

C) P4 MB - Stands for Pentium 4 MotherBoard
This is a 4-pin ATX +12 Volt power cable

D) SATA
Comes with two SATA power cables. You only need one for your SATA harddrive. Tie the unused one up out of the way.

E) Peripheral
Comes with four Peripheral power cables. You only need two for your optical drives. Tie up the unused two.

F) FDD
For a Floppy Drive. Not needed. Tie up out of the way.

G) PCI-E
Also not needed unless someday you install a graphics card that needs this power cable.

Will add a link, to photos and descriptions of the various power cables listed above, that are needed, in additional comments.

NOTE*
Your body carries Static electricity. Movements of your body in your clothes, walking across a carpeted floor, are but two ways static electricity is generated.

Static will fry out (Short Circuit) the components inside a computer.
The preferred method is to buy, and wear an ESD wrist strap as shown in the video.
However you can use another method.

Working on a table, computer unplugged from power, computer case open, simply Touch the metal frame of the open computer case.

Should you get up, and walk away when in the middle of working on your computer, remember to to touch the metal frame again upon your return.

Should you have ANY questions regarding replacing your power supply, please state so in a Comment.

Should you wish to test your power supply, also state so in a Comment.
[Will require a multimeter, or a power supply tester]

did you call gateway they can help you

Try the following:

Check that power supply is plugged in to a live source.

Certain models had an additional power switch on the power supply itself. This would be located to the rear of the computer within 3-4 inches of where the power cord plugs in. Make sure it's on.

Press the power button on the front panel.

Press the space bar. The computer may be in sleep mode..

Gateway desktops usually have a small 'reset' button on the front panel. Press it.

If it still doesn't respond, I'd need to know a little more info before moving forward.

• Are there any lights lit? (K/B, front panel)
• Can you hear a fan?
• Does the monitor turn on?
• What (if anything) has changed since it worked last?
• What was the last thing you were working on?
  
• What model is it?
• What steps have you taken so far?
