HP DC7800 doesn't wake up (and power switch does nothing!)


Bad setting. If you press and hold the power button, the computer will shut off. That will keep you from having to unplug it.

T3418 led pwr


The eMachines T3418 Desktop PC uses an FIC K8MC51G motherboard.

{ FIC = First International Computers, (Inc}

http://www.e4allupgraders.info/dir1/motherboards/socket754/fick8mc51g.shtml

The plastic front of your desktop computer is the Front Panel.

The area of the motherboard that the wires from the Front panel go to, is the Front Panel header. Also sometimes abbreviated as F_PANEL, or FP1.

With the motherboard sitting in it's normal position in the computer case, Processor to the top, Ram Memory to the right; the Front Panel header is to the bottom/right corner.

http://support.gateway.com/s//MOTHERBD/FIC/105554/105554nv.shtml

Click on Product Views in the list.
Now go down, and click on the blue, M- Front Panel Connector.

As you can see the Top row of pins, (Towards the Processor), are numbered Even.
The Bottom row of pins is numbered Odd.

Pins are numbered from Left to Right.
Top row = Pins 2, 4, 6, 8, and 10
Bottom row = Pins 1, 3, 5, 7, and 9

A) Pins 1 and 3 are for the HarDDrive Activity LED light.
Pin 1 is probably for the Positive ( + ) wire. Doesn't say.
If the LED light is dim when operating, switch the wires around.

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

C) Pin 9 is for 5 Volt power.
(Doubt it is used)

D) Pins 2 and 4 are for the Power On LED light.
Probably pin 2 is for the Positive ( + ) wire.
If the LED light is dim when the computer is on, switch the wires around.

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

F) Pin 10 is N/C. Not Connected. (Not present)

[ Just to add:
The motherboard chipset is an Nvidia C51G, Northbridge chip,

http://en.wikipedia.org/wiki/GeForce_6_Series#GeForce_6100_and_6150_series

,and an Nvidia MCP51G, Southbridge chip.

In the photo on the Gateway Support page, the Northbridge chip is under the black finned heatsink, which is in-between the Processor, and black PCI-Express x16 slot.

The Southbridge chip is also under a black finned heatsink, and is to the right of the blue PCI slots, and below the two black ram memory slots.

(Color of the two Heatsinks may not be Black. Could be Gold colored, or bare aluminum, also)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

(CPU = Central Processing Unit. Another term used is Microprocessor, or Processor for short )

T5244 motherboard diagram?


I am not aware that there is an eMachines T5244 Desktop PC.
Do you mean T5224?

Going with the model number T5244,..........

The eMachines T5224 Desktop PC uses an Intel D945GCL motherboard.

Installed in your computer case with the Processor to the top, Ram memory slots (2) to the right, black PCI-Express x16 slot and white PCI slots (3) to the bottom, it looks like this,

http://www.ebay.com/itm/INTEL-D945GCL-SOCKET-LGA-775-mATX-MOTHERBOARD-945G-ICH7-/370485278057?pt=Motherboards&hash=item5642a4b569

The plastic Front of the computer case is the Front Panel.

The area of contact pins on the motherboard, that the Power On button, (Switch), Power On LED light, and Harddrive activity LED light, wires connect to, is the Front Panel header. (May be abbreviated on motherboard as FP1, or F_PANEL1 )

The Front Panel header, is at the bottom Right corner of the motherboard.

This is Intel Support > Intel D945GCL motherboard > Product Guide download page, (Motherboard Manual),

http://www.intel.com/support/motherboards/desktop/d945gcl/sb/CS-023154.htm

Click on the first file listed in blue -
Intel Desktop Board D945GCL Product Guide - English (PDF)

This is a PDF file. 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.

If you are aware of the following disregard;
The page number for the PDF file, does not always correspond to the page number of the manual, with most PDF files.
This particular PDF file does.

The page number box is in the top header, to the Right of the Down Arrow.
You can use the Down Arrow, (Or Up Arrow when needed), to arrive at the desired page, or;

1) Put your mouse cursor in the page number box. Left-click once. (Number/s in page number box are then highlighted in blue)

2) Type the desired page number
3) Press the Enter key

The view size can be changed with the Zoom In/Zoom Out icons, in the top header of the PDF file.
Zoom In ( + ) increases the view, Zoom Out ( - ) decreases the view.
( I use 75 to 100 percent, normally)

To go on;
For the Front Panel header pinout, start on Page 11 looking at the Top View of the motherboard.

The letter V points to the Front Panel header.
(View of motherboard is turned 90 degrees to the right, in comparison to how it is actually sitting in your computer case )

Looking at the Front Panel header, to how it is actually sitting in your computer case, the Front Panel header is a rectangular header with two rows of contact pins.

Go to Page 43.
5 pins across the Top, 4 pins across the Bottom.
The pins are numbered.
Numbered Odd for the pins going across the Top, and Even for the pins going across the Bottom.

Starting at the RIGHT side of the Front Panel header, (Right side of motherboard), and going towards the Left side on the Top row, the pins are numbered,

1, 3, 5, 7, and 9

Starting at the Right side of the Front Panel header, and going towards the Left side on the Bottom row, the pins are numbered,

2, 4, 6, and 8

A) Pins 1 and 3 are for the HarDDrive Activity LED light.
Pin 1 is for the Positive ( + ) wire.
If the HDD 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.

C) Pin 9 is N/C. No Connection

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

{ NOTE**
The Power On LED light may not use the Front Panel header.
It may use the small rectangular header, above the Front Panel header.

This alternate Power On LED header has 3 pins.
Pin 1 is all the way to the Right. (Pin 3 all the way to the left, Pin 2 in the middle)

Ordinarily if a Power On LED light just has one color, it is attached to the Front Panel header.
It CAN be attached to the alternate header, however. It is attached to Pins 1 and 3.

Pin 1 being the Positive connection ( + ), Pin 3 being the Negative ( - ) connection.

Some computer models used Turbo Mode. Supposedly kicking the computer up to a faster speed.
These model's Power On LED light had dual colors.

Example Green for ordinary mode, and Yellow for Turbo Mode.
Pins 1 and 2 are used for the Positive connections. (Green and Yellow, for example). Pin 3 is used for the Negative connection.

Side Note*
The computers did not essentially go to a faster speed.
When in non-turbo mode, the computer is operating at less than it's full capability. ('Speed')
When in Turbo Mode the computer is operating at it's normal capability.
There was NO increase in power, in reality }



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

[ NOTE*
BEFORE reaching inside your computer, observe Anti-Static Precautions, and have the power Unplugged to computer.

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

De-Static your body before working on the computer. (And occasionally during doesn't hurt)
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.
Should you leave your computer in the middle of working on it, be SURE to Touch the metal frame again, upon your return ]

Power Supply cable connections: (Page 48)
1) The 24-pin ATX main power cable connects to the motherboard, to the white connector on the motherboard with 24 socket holes. It is to the right of the Ram Memory slots.

The male connector of the power cable, has a Lock on the side. The female connector on the motherboard, has a Notch for the Lock.
The Lock operates in the same fashion as a see-saw on a playground.

The top of the Lock is gently squeezed in, and this brings the hooked end of it, away from the Notch on the female motherboard connector.
When this Lock is firmly hooked into place, then it is known that the power cable is plugged in securely, and correctly.

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

2) Same for the 4-pin ATX +12 Volt power cable. It has a Lock also.
This power cable provides power for the Processor. (CPU)

This power cable, plugs into the whitish square connector with 4 socket holes, to the Left of the Processor. (It is next to the purple 25 pin Printer connector)

Example of a 4-pin ATX +12 Volt power cable,

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

Note the two Yellow 12 volt wires, and the two Black ground wires, in the cable.

3) One SATA power cable to the Harddrive.
(At least according to eMachines Support. Support doesn't state whether the optical drive { DVD-R/W} is an IDE unit, or SATA )

Long 15-pin connector with L-shape connection.
(The shorter 7-pin connector is the DATA cable. It also has a L-shape connection)

4) 4-pin standard Peripheral power cable/s.
(Also misnomered as a 'Molex' power cable)
If you have an IDE (PATA) harddrive, this is a power cable for it.
IDE (PATA) optical drives also use this power cable.

The computer case (Chassis) fan attaches to the small white 3-pin header, next to the round CMOS battery.

How to find out which wires are the Power On switch, Power On LED, and Harddrive activity LED wires?
You may have to remove the Front Panel, and follow the wires.

It is simple to trace the wires to the Power On switch, and Harddrive activity LED light. The Power On LED wires are then found.

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.
