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.

Missing power pack some ribbons


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.

THE WIRES CONNECTING HARDDRIVE TO HP PAVILION503n


The HP Pavilion 503n Desktop PC uses an IDE (PATA) harddrive,

HP Support > Pavilion 503n Desktop PC > Main Support page,

http://h10025.www1.hp.com/ewfrf/wc/product?product=90381&lc=en&cc=us&dlc=en&lang=en&cc=us

In the list click on - Product information
Now click on - Product specifications
Lastly click on -
Motherboard Specifications, TriGem 2002052 (Glendale)

Takes you to this page,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07813&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=90381

Scroll down, and look at the motherboard illustration, and photo.

Viewing the illustration look at the bottom right.
Primary IDE is where the harddrive plugs in.

In the motherboard photo this is the long Blue connector.

Now lets view an IDE 'ribbon' cable,

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

Click on the photo to the upper right that shows the IDE cable, and it's blue connector. (The photo on the left of it shows the motherboard connector)

Here you see the rectangular connector, and a small square 'bump' on top.
The bump is a Locating Lug.

This lug is lined up with a cutout, in one side of the motherboard connector.
The other end of the cable's Locating Lug, lines up with a cutout on the back of the harddrive.

IF, there is no Locating Lug on the IDE cable connector;

There is a faint red stripe on one side of the cable. This is Always on the same side as number 1 wire, in the cable.

On the above link scroll the page down towards the middle, and the IDE cable illustration. (Under the heading - Parallel ATA Interface )

Number one contact pin on the harddrive, is ALWAYS towards the power connection, on the harddrive.

Example,

http://wdc.custhelp.com/app/answers/detail/a_id/463/c/123/session/L3RpbWUvMTMzNjA1OTI2Ni9zaWQvRm95eENiWGs%3D

The above is for a Western Digital IDE harddrive, and shows the jumper settings.
I posted it for the back view of the harddrive.

Look at the where it states - 40-pin IDE connector.
Now look at the right side where it states - Power connector

When the IDE flat ribbon cable is plugged into the harddrive, the faint red strip faces - Power connector

On the motherboard look at the blue connector stated above.
Looking at it with the optical drive connector above it, (Secondary IDE),
the red stripe goes to the LEFT.

With the IDE cable plugged into the Primary IDE, and the Secondary IDE connector above the Primary IDE connector, the faint red stripe goes to the LEFT.

Need an IDE cable?

Proper installation of tower wires


According to Gateway Support, the Gateway 505GR desktop computer uses an Intel (Ausberg) 915G motherboard,

http://support.gateway.com/s/PC/R/3724/3724iv.shtml

Intel (Ausberg) 915G motherboard,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

Scroll down to the photo with the sections marked in red.

In the top link, looking at the motherboard with the computer case open, the USB and Firewire (1394a) cables, can be seen attached to the motherboard near the letters D, E, and F.

In F that red cable is a SATA cable. One end attaches to the back of the SATA harddrive, (The angled end), and the other end of the SATA cable attaches to one of those SATA headers on the motherboard.
(SATA header = SATA connector on motherboard)

Preferred SATA header for the Harddrive is SATA 1.
DOESN'T matter though. That's the beauty of SATA. You can plug the SATA data cable into ANY SATA header on the motherboard, and BIOS will find the harddrive.


In the second link, looking at the motherboard photo shown, and comparing it to the view of the motherboard as mounted in the computer case, the Front Panel header is at the very Bottom Right.

Two rows of pins in a White rectangular shaped header,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

(S points to Front Panel header)

[ The plastic front of a desktop computer is the Front Panel.
The area of pins on the motherboard, that the Front Panel wires go to, is the Front Panel header ]

A) Top row has Even numbered pins
B) Bottom row has Odd numbered pins.

http://www.intel.com/support/motherboards/desktop/sb/CS-009016.htm

1) Power LED = Power On LED light
2) Hard Drive Activity LED = LED light that flashes (Usually red in color) when your harddrive is active. Being used.
3) Reset switch = Reset Button. The Reset switch is behind the Reset button. (IF the computer uses a Reset switch)
4) Power Switch = Power On switch
5) Forget about Pin 9. That's for 5 Volts DC - Out. Used by factory.

Which wires coming out of the Front Panel, are the Power On wires, Harddrive LED light wires, Power On switch wires, etc.?

Remove the Front Panel, and trace where the wires end.

IF, the wires already installed coming from the motherboard to the Front Panel, are Too short, you should make notes before you remove them from the motherboard.

Note what color pair of twisted wires, went to where, in the Front Panel.
Compare to the chart of the Front Panel header given above.
(IF any wires are still connected to the Front Panel header on the motherboard)

Once the Front Panel is removed, it's usually pretty easy to trace the two wires up to the Power On switch.
Same for the Power On LED light.
Again, same for the HarDDrive activity LED light.

The SATA harddrive requires a DATA cable, and a SATA power cable.

The connector for a Data cable has 7 contact pins. It is the shorter connector.

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

The connector can be at a 90 degree angle as shown, or a straight connector.
IF the data cable has an angled connector, it plugs into the Harddrive.
Straight connector goes to the motherboard.

The connector for a SATA power cable has 15 contact pins. It is the longer connector,

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

Note the L shape of the connectors for the SATA data cable, and SATA power cable.

Also;
This is a 4-pin standard Peripheral power cable. Commonly misnomered as a 'Molex' power cable,

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

IF, the SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable.

Using both power cables will burn up the harddrive.
May not happen immediately in some cases, but WILL eventually happen.

For additional questions please post in a Comment.

Burnt connector inside dell inspiron, first connector at motherboard (after power box) Can I fix it?? If so, can u help??


LOVE your user name!

I'll try to guide you the best that I can.
Sorry, first connector after Power Supply does me no good.

Let's look at a basic schematic of the motherboard for a Dell Inspiron 530s Desktop PC,

Dell Support > Inspiron 530s Desktop PC > Dell Inspiron 530s Series Owners Manual,

http://support.dell.com/support/edocs/systems/insp530s/en/OM/HTML/index.htm

I would like you to click on - Removing and Installing Parts
In the left column click on - System Board Components
{System Board = Motherboard }

This is a basic view of the motherboard with No hardware components installed.
It is also how the motherboard sits in your computer.

This is a pictorial view of the motherboard,

http://www.amazon.com/Dell-Motherboard-Inspiron-Systems-Compatible/dp/B003CO0WQS

Now, compare the Dell Support motherboard illustration, to the pictorial.
Looking to the far right in the illustration, the first connector is marked with the number 8.

On the pictorial it is the rectangular Black connector at the bottom/middle. (Next to the rectangular White connector)

This connector is for a Floppy Drive.
Is this the connector in question?

Is it the white rectangular connector next to it?
This connector is for the main power cable coming from the Power Supply.
In the illustration is is marked by the number 7.

This is a basic example, of the power cable coming from the Power Supply (power box), that connects to the white connector,

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

{Note* Color of the main power cable's connector does not matter. It can be any color }

IF this connector on the motherboard is burnt, you may wish to stop.
Electricity has more than likely fried the entire motherboard. May also include the Processor, Ram Memory, Harddrive, and a graphics card, if installed.

I know. I'm a 'ray of sunshine'.

How could this connector be burnt?
Four ways I know of;

1) Lightning storm, or power outage. Also could have happened if the power utility company was doing some changes in the power lines, utility pole transformer, etc.
(No. The utility company cannot be held responsible. I don't agree with that)

2) Power cable was not plugged in tightly. Lock on side was not locked into place.
Air gap created in-between the connecting contacts in the power cable connector, and the motherboard connector, created resistance.

Resistance creates heat. Burnt connector/s will result, and perhaps worse.
{Could also create a small power surge }

3) At one time Dell was a Proprietary computer manufacturer.
This means Dell wanted THEIR replacement parts used on THEIR computers.

If an aftermarket computer component is installed, Dell cannot warranty their computer.
Using THEIR parts in THEIR computers, Dell could.
However Dell computer users did not wish to pay the price of the Dell replacement parts.
The aftermarket parts were cheaper, of good quality, and readily available.

If we use a Power Supply for an example;

Dell had the motherboard manufacturer switch the socket holes around, in the Motherboard connector, for the main power cable.

They also had the Power Supply manufacturer switch the pins around, in the 24-pin ATX main power cable's connector, to match.

The aftermarket power supply manufacturer built the power cables, and connectors, to follow industry standards. Dell did not.

This means if you plug an aftermarket power supply's main power cable, into a Dell motherboard that was built proprietary, the motherboard usually fried. The only sign may be a burnt connector on the motherboard.

Could also have fried the Processor, Ram Memory, Harddrive, optical drive/s, and a graphics card, IF installed.

[ Looking at the Playtool link again, look at the photo to the far right.
See the different colored wires?
The color coding indicates what the wire carries as far as Voltage, or if it is a Ground wire.

1) Orange insulated wires = 3.3 Volts
2) Red wires = 5 Volts
3) Yellow wires = 12 Volts
(All are DC. In comparison two D cell flashlight batteries produce 3 Volts DC)

4) The Black wires are Ground wires

(The Green wire is the Soft Power On wire. Abbreviated as PS_ON)

The Orange, Red, and Yellow wires are power wires.
The Black wires are Ground wires.
Guess what happens if a 12 Volt wire is connected to a Ground?
(Instead of going to a 12 Volt connection)

Things start frying.

{To state connections in the main power cable connector, and it's respective connector on the motherboard, correctly;

Looking at the middle photo you see the connection end of the main power cable.
Plastic connector with individual plastic rectangular shapes, that have metal 'tubes' inside each of them.

The motherboard connector has socket holes to match the individual plastic rectangular shapes.
Inside the socket holes are metal pins. Contact pins.
The contact pins go inside the metal 'tubes'.

The metal 'tube' is a Molex Socket Terminal,

http://www.mouser.com/ProductDetail/Molex/36664-0002/?qs=sGAEpiMZZMvz8LftK4jerhl0r50z%252bUNRzFCdHbJqUTU%3d


4) IF the Power Supply, ( looking at it from the Back of the computer), has a rocker switch, or slide switch, to set the incoming AC power to 110 Volts, or 220 Volts;
And the power supply switch was set to 110, and plugged into 220 Volts,
the motherboard connector would fry.

Plus the Power Supply. May also of course include Processor, Ram Memory, Motherboard, Harddrive, optical drive/s, and graphics card IF installed.


Replace the connector? No
Could be;
A) Replace the Power Supply. Still no?
B) Replace the Motherboard. Still no?
C) Replace the Ram Memory. Still no?
D) Replace the Processor. Computer operates but no graphics?
E) Graphics card installed? Replace graphics card

Unless you can test each individual component, and the cost is not much less, or equal to a new computer, the obvious choice would be to purchase a new, or good used computer.

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

Front Panel header:

This link takes you to Intel Support, and the download page for the motherboard manual, for the Intel D101GGC motherboard,

http://www.intel.com/support/motherboards/desktop/d101ggc/sb/CS-021718.htm

On this page click on the blue -
Intel Desktop Board D101GGC Product Guide - English (PDF)

The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name it may take up to 30 seconds before the first page comes up.
It may also take additional time for the file to fully download.

{ Took 7 seconds to download just now, with no additional download time needed.
Using medium speed DSL connection }

Ignore the following if you are aware;
At the top of the PDF file is the PDF file page number box, and the Zoom Out/Zoom In icons.

Zoom Out ( + ) enlarges the page view, Zoom In ( - ) reduces the page view.
For myself I reduce the view size to 100 or 75 percent.

The page number box is to the right of the Down Arrow.

(If you do not see this, hover your mouse cursor towards the bottom/middle. When the icons come up, {They were 'ghosted out'}, click on the PDF icon to the far right )

Provided that somehow you cannot download this motherboard manual;

Orient the motherboard so we are both looking at it in the same direction.
Same as it sits in the computer case.

Processor to the Top, Ram Memory to the Right, white PCI slots to the bottom.
The Front Panel header is at the Bottom/Right.

It is a rectangular block of plastic with two rows of pins.
4 across the Top, 5 across the Bottom.

It is numbered Even on the top, and Odd on the bottom.

Starting at the LEFT side going towards the right, on the top row;
Pins 2, 4, 6, and 8.
There is no Pin 10, just an empty space.

Starting at the LEFT side going towards the right, on the bottom row;
Pins 1, 3, 5, 7, and 9

A) Pins 1 and 3 are for the HarDDrive activity LED light. (Orange)
Pin 1 is for the Positive wire ( + )
If the LED light is dim when operating, switch the wires around.

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

C) Pin 9 is for 5 Volts. Not Used (Black)

D) Pins 2 and 4 are for the Power On LED light. (Green)
Pin 2 is for the Positive wire ( + )
If the LED light is dim switch the wires around.

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

Do not know what wires coming from the Front Panel are the Power On switch wires, Power On LED light wires, or Harddrive activity LED light wires?

Remove the Front Panel, trace the wires to the Power On switch. (Two wires. Probably twisted together. Or all wires are in a single sheath)

Same for the Power On LED light, and the Harddrive LED light.

Need to know where the harddrive, or optical drive plugs in?
Need to know where the power cables from the Power Supply plug in?
Please post back in a Comment.

We took our case apart to clean the fans. unfortunately once we had them clean and put back on the on-off switch would not come on it will not power up, the fan is going the green light on the back is on.....


1) Remove the Ram Memory module/s, and reinstall them.

It may look as though they are seated, by they may not be. All it takes is a slight bump.

I would also advise cleaning the contact pins while the ram memory module/s are out.
Use a pencil eraser.

{Note*
Computer unplugged from power, observe Anti-Static Precautions.

Anti-Static Precautions:

Your body carries Static electricity.
Static WILL fry out (Short Circuit) the hardware components inside a computer.
You won't see it or feel it.

Relieve your body of Static Before you reach inside your computer. (And before you remove any new hardware parts from their protective anti-static cartons)
Computer on a table, computer unplugged from power, computer case open.
TOUCH the metal frame of the open computer case to relieve your body of Static.

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


If you are not using a solid eraser, and one on the end of a pencil, refrain from letting the metal band touch the contact pins.

The Presario SR1403wm desktop computer supports DDR Sdram ram memory modules.
There are 184 contact pins. 92 on each side.

Rub the eraser up, and down on each contact pin, both sides of the ram memory module.
Doesn't take as long as it sounds.
Just go up, and down a couple of times, you don't need to scrub the contacts with the eraser.

It may look as though you have done nothing at all once you're finished. The gold plated contact pins will not be shiny.
I assure you that you have.
Doesn't take much corrosion to make a bad contact surface.

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

(You can click on the photo to enlarge)



2) Perhaps one of the power cables wasn't attached to the motherboard.
Here is an illustration and photo of the Presario Sr1403wm motherboard,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00257657&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&site=null&lang=en&key=null&product=501310

Scroll down towards the bottom of the page.

In the illustration where it states the chipset SiS 760 in a rectangular outline, look to the right of it.
There is a small square outline with > ATX12V1 above it.

This is for the 4-pin ATX +12 Volt power cable.

Example of a typical 4-pin ATX +12 Volt power cable, and the matching connector on the motherboard,

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

Be sure this power cable has been attached.

To the right of the motherboard connector ATX12V1 is the main power cable connector
ATXPWR1

On the motherboard photo look all the way to the right side, and in the middle.
The whitish connector that has 2 columns of 10 socket holes is the ATXPWR1 connector.

This is an example of a typical 20-pin ATX main power cable, and it's matching connector on the motherboard,

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

Both connectors have a Lock on the side of the male connector. The connector that has the wires in it.
The female connector on the motherboard has a tab on the side.

To ensure that the male connector is seated tightly into the motherboard connector, the Lock's hooked end must be over the tab on the motherboard connector.

If both of these power cables are not fully seated, the computer will not turn on.



3) Harddrive power cable:

The harddrive used is a SATA harddrive.

This is an example of a typical SATA power cable,

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

Make sure this power cable is seated well, into the SATA harddrive.

[ Note*
The SATA power cable has 15 pins. The SATA data cable has 7 pins.

IF, your SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY USE the SATA power cable.
Using both power cables will burn up the SATA harddrive.

Some SATA drives will operate for a while with both cables plugged in. Then they eventually burn up.

Example of a typical 4-pin standard Peripheral power cable,

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

(Shown plugged into an IDE {PATA} harddrive)

With all power cables attached, and seated well, plus the ram memory module/s, make sure the Front Panel cable is connected in the proper place on the Front Panel header.

In the illustration F_Panel 1 is the Front Panel header.

{The plastic front of your computer is the Front Panel.
The area of pins in the connector on the motherboard, that the Front Panel cable connects to, is the Front Panel header.
This particular Front Panel cable is for the Power On switch, HarDDrive Activity LED light, and Power On LED
Not the cables for the USB ports, or Firewire port/s in the Front Panel)

If everything checks out above, then either the Power On switch is bad, or the Power Supply is bad.
Happens. A power supply can go out all at once.
Weak voltage power rail.

I can guide you with a simple test to see if the problem is the Power On switch, or the Power Supply.


If you have further questions please post in a Comment.
Would appreciate hearing how this comes out.

Hello I have a T2682 and I have taken this computer apart many times and I just got back from Afghanistan and just wanted to see if I could get it going one last time but I forgot what wires plug in where...


The beep you hear is a BIOS Beep Code. The computer's method of informing you something is wrong, and the area to look into for it.

The code is similar to what you may be used to.
(Afghanistan, Army? If so, hello brother/sister. 1st Cav, 13th Sig. Corp)

The BIOS Beep Code is similar to a Morse Code.

Examples:
Two short beeps followed by a long beep, a pause of silence, then the pattern repeats, over, and over.

One short beep indicates everything is okay.
This is an indication that BIOS has concluded the Ram Memory count, and everything is 5 By.

According to my sources, the eMachines T2682 desktop computer uses an Imperial GV motherboard model, made by TriGem.

The front plastic cover of your computer is the Front Panel.
The area on the motherboard that the cables, (Wires), attach to on the motherboard, is the Front Panel header.

This is the Front panel header pinout, for the TriGem Imperial GV motherboard,

http://www.e4allupgraders.info/dir1/ecase/support/front_panel_support.shtml

On this page I would like you to scroll down to the heading -
Imperial GV Front Panel Motherboard Pinouts

Looking at the pinout;

1) Pin 1 is Not used. NC = No Connection

2) Pins 2 and 3 are for the Power On LED light
[Light Emitting Diode]

Pin 2 is for the Ground wire. (GND) ( - )
Pin 3 is for the LED light power wire. ( + )

3) Pin 4 is not used. NC

4) Pins 5 and 6 are for the Harddrive Activity light. (LED)
HDD is HarDDrive

Pin 5 is for the LED power wire
Pin 6 is for the HarDDrive signal wire
(If after attaching the wires the HDD LED light is dim, reverse the wires)

5) Pins 7 and 8 are for the Power On switch.
Pin 7 is for the Ground wire.

Attaching the Peripheral cables;

1) You have an IDE harddrive. Uses a 40-pin IDE ribbon cable.
(39 actually. One pinhole is blocked off)

There is a Locating Tab on one side of the IDE ribbon cable's connector.

To wit:

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

Left-click on the blue IDE connector in the photo to the upper right.
At the top middle of the connector you will see two ridges.
This is the Locating Lug.

Now left-click on the IDE connector on the motherboard, shown in the photo to the upper right.
(To the right of the blue IDE connector)

Looking at the blue IDE connector on the motherboard, you will note there is a cutout on one side of the connector.
This is a Locating Slot.

Lining the Locating Lug up to the Locating Slot, puts the pins of the IDE ribbon cable's connector, in the correct position for the pinholes in the motherboard's IDE connector.

IF, your ribbon cable's connector does Not have a Locating Lug;

Look at the outside edge of the ribbon cable. You should see a faint Red stripe.
The Red stripe is always next to Pin 1.

Next to the motherboard's IDE connector should be a printout.
It will state PRI 1, (Stands for Primary 1), or IDE 1.
This is for the Harddrive.

[ If you see PRI 2, or SEC, (Secondary), this is for the optical drive.
(CD/DVD drive). Using this information, you will know the other IDE connector on the motherboard is for the Harddrive ]

That printout is always next to where Pin 1 is.
Therefore on the motherboard, the side of the IDE ribbon cable that has a Red stripe, will go next to the printout.

If your harddrive does not have a Locating Slot on it's IDE connector, Pin 1 is always towards the 4-pin IDE power pins.

To wit:

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

The above is a webpage from Playtool.com, discussing the various power cables used in a PC, and more specifically the standard 4-pin Peripheral power cable.

I linked it to show you a standard 4-pin Peripheral power cable, plugged into an IDE harddrive.

(A Peripheral power cable's connector, has been misnomered as a Molex connector, repeatedly through the years.
This was the name given to the first connector of this design.
It's kind of like referring to an adjustable open-end wrench, as a Crescent wrench )

Here in the photo of the rear view of an IDE harddrive, (Photo to the far left), you will see the 4 power pins.

To the left of the power pins are the Jumper pins.
To the left of the jumper pins, is the IDE interface for the 40-pin IDE ribbon cable.

The Red stripe of the IDE ribbon cable goes towards those 4 power pins.

To be continued in an additional comment.

Dell computer will not turn on.


Somewhere on in the tower there should be a sheet representing what formations of lights mean which...
Maybe you got bad RAM?
Maybe your Harddrive is dead?
Maybe your motherboard is fried. I should tell you.
Good luck.

Could be a bad motherboard? If your power supply was really fried it could have also fried your motherboard.
