    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.

There is the motherboard manual

Example A;

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.
(Power On switch, Power On LED light, HarDDrive activity LED light, and Reset switch IF used)

The Front Panel header is JFP1, in the bottom/right corner of the motherboard.

Two rows of contact pins.
4 on the Top row.
5 on the Bottom row.

Pins across the Top row are numbered EVEN.
Pins across the Bottom row are numbered ODD.

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

Starting from the Left side going 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 is reserved for the factory to use.
(Believe 5 Volt test point)

D) Pins 2 and 4 are used for a Power On LED, that has two wires.
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.

JFP2, or also known as Junction Front Panel 2; is above JFP1, and is situated Vertically, instead of Horizontally like JFP1.

(Below purple SATA data cable connector/ Right; and to the immediate right of the CMOS battery))

4 pins on the Left side, 3 pins on the Right side.
Pins on Left side are numbered EVEN.
Pins on Right side are numbered ODD.

Starting at Top of Left side coming down;
Pins 8, 6, 4, and 2.

Starting at the Top of the Right side coming down;
NO Pin 7, pin 5, pin 3, and pin 1.

Pins 2 , 4, 6, and 8 are for an internal speaker. Used to hear BIOS Beep Codes.

Pins 1, 3, and 5 are for a Power On LED light, that has 3 wires.
Used for a dual color Power On LED light.
For example Turbo Mode is Green, and Normal Mode is Yellow.

(Which was cr@p.
Turbo mode was actually normal, while normal was slower)

Example B)
Front panel USB ports. (Connectors)
JUSB1 and JUSB2.

EACH USB header supports TWO USB ports.

Look at the pinout on Page 40.
VCC, USB4-, USB4+, and Ground; is one USB connector. (port)
VCC, USB5-, USB5+, and Ground; is a second USB connector. (port)

Note the USB4-, and USB4+; and the USB5-, and USB5+

Now look at a USB pinout. Male and Female,

http://en.wikipedia.org/wiki/Pinout#USB_pinout

VCC = +5 Volt
USB4- and USB5- = -Data
USB4+ and USB5+ = +Data
GND is Ground.

You can have 4 USB ports in the Front Panel, or add extra ones to the rear panel. (I/O area)

ONE of those USB headers; JUSB1 or JUSB2; can be used for a Card Reader.
A Card Reader has Two USB cables, and uses One USB header on the motherboard.

Which one? Junction USB1, or Junction USB2?
Pick one.
Doesn't matter.
BIOS will set an IRQ for it.
(Interrupt ReQuest)

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.
You need a Front Panel header pinout.

When I refer to a page in the manual, it will be for the Adobe Reader page number box, at the top.
Go to Page 1-7
1.5.3 Motherboard layout

Number 12 shows us the Front Panel header.
Motherboard mounted in computer case, the Front Panel header is the 3rd header from the Left; on the bottom of the motherboard.
(System panel connector (10-1 pin F_PANEL)

Go to Page 1-25
System panel connector (10-1 pin F_PANEL)

There are two rows of pins.
4 pins across the Top row; 5 pins across the Bottom row.
Not numbered, so I will;

Starting on the LEFT side, going across to the Right; Top row,
Pins 2, 4, 6, and 8. There is NO Pin 10

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

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

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

C) There is NO Pin 10.

D) Pins 1 and 3 are for the HarDDrive activity LED.
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 a 5 Volt (DC) point for the factory to test with.
(So it's Reserved for the factory)

Here is an example of an ATX power on switch, that is used in MANY desktop computers,

http://www.directron.com/atxswitch.html

Remember; the Power On switch is a Momentary Contact Switch.
This means the contact period you make across those two pins, shouldn't be more than 2 seconds.

Next time you do not know the Front Panel header pinout, of a motherboard;
Use an LED light with two wires.

Touch two pins at a time, going along the FP header.

Computer turns on? You have the Power On switch pins. Now you can continue on.

LED light stays on? You have the Power On LED pins.
LED light blinks? You have the HarDDrive activity LED pins.
Computer restarts? You have the Reset switch pins.

Power On LED winks at you seductively?

Put that left-handed cigarette down, and go get sum fresh air.

MX46-633V CONNECTING FRONT USB


I believe you're referring to the AOpen MX46-533V

The Front Panel USB header is Blue in color, and located in-between the white No.3 PCI expansion slot, and bottom edge of the motherboard;

http://www.ebay.com/itm/AOpen-Model-MX46-533V-Socket-478-Desktop-System-Motherboard-/130774572519?pt=Motherboards&hash=item1e72c59de7

With the motherboard in the installed position;
5 pins across the Top row, 4 pins across the Bottom row.

Pins across the Top row are numbered EVEN
Pins across the Bottom row are numbered ODD

Starting on the Left side coming across to the Right, Top row;
Pins 2, 4, 6, 8, and 10

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

There are TWO USB connectors supported off of this USB front panel header.

For one of the USB front panel connectors;

A) Pin 1 is USB PWR 0
Goes to the VCC contact pin on the USB connector.

B) Pin 3 is USB_FP_P0-
Goes to the D- pin on the USB connector.
(Data - )

C) Pin 5 is USB_FP_P0+
Goes to the D+ pin on the USB connector
(Data +)

D) Pin 7 is Ground (GND)
Goes to the Ground (GND) pin on the USB connector

E) No pin 9

F) Pin 2 is USB PWR 0

For the other Front Panel USB connector;

A) Pin 2 is USB PWR 0
Goes to the VCC pin on the USB connector

B) Pin 4 is USB_FP_P1-
Goes to the D- pin on the USB connector

C) Pin 6 is USB FP P1+

This is more information on a standard USB connector pinout,

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

( A USB connector, and a USB plug are not wired the same.
The plug is wired backwards from what a connector is.
Otherwise you would have power and signal going to the wrong pins, and burn the USB Front Panel header out on the motherboard )

AOpen MX46-533V motherboard manual, but it is in Japanese.
May be one in English out there.
The Front Panel header pinout, USB header pinout, etc, is easily cross identified,

Motherboard Layout

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.

JFP1 is the Front Panel header.
JFP2 is an additional header. To be discussed after JFP1.

JFP1 is on the Right/Bottom corner. It is placed Vertically.
(Parallel to the right bottom edge of the motherboard)

Above it's left corner is JUSB2. (Front Panel USB header 2)
Above JUSB2 is the SATA2 connector. To the left of the SATA2 connector is the SATA1 connector.
To the left of the SATA1 connector is the CMOS battery.

The contact pins are arranged in two columns.
4 pins on the Left side, 5 pins on the Right side.

Go to Page 14. JFP1 pinout, and JFP2 pinout, is at the Bottom of the page.

JFP1:
Starting on the Bottom going towards the Top, Right side;
Pins 1, 3, 5, 7, and 9

1 Answer

I am looking forthewireing for a hp pavilion xt919


A) Power cables from Power Supply to motherboard:

1) Product information > Product specifications > HP Pavilion XT919 Desktop PC Product Specifications and What Ships in the Box,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph06613&tmp_task=prodinfoCategory&cc=us&dlc=en&lc=en&product=58461

2) According to my sources the motherboard is an Asus CUW-AM,

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=120&prodSeriesId=46171&prodTypeId=12454&prodSeriesId=46171&objectID=bph07170

If this indeed holds to be true, scroll the page down, look at the illustration under the Figure 1: Motherboard layout, heading.
Look at number 22 on the right; ATXPWR

Now scroll down to the motherboard photo.
The white connector with two columns of 10 socket holes, to the right of the black Ram memory slots, is ATXPWR.

Proper name is 20-pin ATX main power cable connector, on the motherboard. This is an example of a 20-pin ATX main power cable, and it's respective motherboard connector,

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

Note in the three photos the Lock on the side of the power cable connector, and the Tab on the side of the motherboard connector.
The Lock operates like a see-saw on a playground.

To remove the power cable the top is squeezed in, and this causes the hooked end of the Lock to come away from the Tab.
When the 20-pin ATX main power cable is deemed to be properly installed tightly to the motherboard, the hooked end of the Lock will be over the Tab.

B) IDE (PATA) harddrive uses a 4-pin standard Peripheral power cable.
So does the Optical Drive/s,

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

Note the rounded corners when plugging it in.
{Power cable has been misnomered as a 'Molex' power cable. Molex came up with the connector design. The name stuck. Kind of like calling an adjustable open-end wrench a Crescent wrench }

C) Floppy drives and card readers use a 4-pin small Peripheral power cable,

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

D) Number 6 -> SYS_FAN, is where the Processor fan plugs in.
SYS_FAN stands for System Fan. A computer case fan. The illustration is wrong.

E) Number 21 is PS_FAN.
That to me stands for Power Supply Fan. Another misnomer. The Power Supply has it's own fan, and doesn't need power from the motherboard for it.
I'll bet this is where a System Fan, or computer case fan, would connect.

F) Number 29 points to the Primary IDE connector on the motherboard.
This is where the 40-pin IDE flat ribbon cable, plugs in for the Harddrive.

Number 24, Secondary IDE, is where the Optical Drive's, IDE flat ribbon cable plugs in.

Note*
The rectangular connectors for the IDE flat ribbon cables, has a 'bump', or protrusion, on the outside edge towards the middle,

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

In this photo it is at the top/middle. There are different styles. Square block, or the two piece design shown.
These bumps, or protrusions line up with a cutout.

A cutout on the motherboard connector, or a cutout on the circuit boards for the harddrive, and optical drive.

IF there is no bump, or protrusion;
There is a faint red strip on one side of the IDE (PATA) flat ribbon cable.

The red strip denotes which side Number 1 wire is on. Number 1 wire in the cable, for number 1 pin in it's connector/s.

http://pinouts.ru/DiskCables/IDE_pinout.shtml

Here you can see by the pinout above, that for the black Primary IDE connector, and the blue Secondary IDE connector, Number 1 pin is at the Top.
Red stripe on edge of IDE cable will be at the top, when the cable is attached.

When plugging into a harddrive, or optical drive, Number 1 pin ALWAYS goes toward the power cable.
Towards the 4-pin standard Peripheral power cable.
Red stripe will be towards 4-pin standard Peripheral power cable.

H) Number 14 CD_IN is where the audio cable from the MAIN optical drive plugs into. If you have two optical drives only the main, or Primary optical drive audio cable plugs into the motherboard.

I) 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.

Under the photo of the motherboard, the pinout for the Front Panel header is shown, though not very legible.
In the illustration the Front Panel header is Number 30 - Panel.

Looking at the pinout, and looking at the actual Front Panel header on the motherboard photo, it looks as though they have the pinout upside down, in relation to how it actually is.

Note in the motherboard photo, the Front Panel header is shown with 5 pins across the Top, then a space, then 4 more pins.
The Bottom row is 10 pins in a row.

In the Front Panel header pinout, they show 10 pins going across the Top. 4 pins going across the bottom, a space, then 5 pins.

Upside down.

I think it should be this way,

Top Row starting on the Left side going towards the Right;
Pins 2, 4, 6, 8, 10, No Pin, 14, 16, 18, and 20.

Bottom Row starting on the Left side going towards the Right;
Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.

1) Pins 2 and 4 are for a Reset switch, IF a Reset switch is used.

2) Pins 6, 8, and 10 are for the Power On LED. (Light)
This is for a computer that has 'Turbo'
Dual light Power On LED. May have Green and Yellow lights.

Green for 'Turbo', and Yellow for Normal.
Bunch of hooey, really.

'Turbo' mode is the computer operating in a normal mode, and Normal mode really is the computer slowed down.

Pin 10 is for the Negative ( - ) wire.
Pin 6 and Pin 8 are the Positive ( + ) wires. One for the Green side of the Power On LED, one for the Yellow side of the Power On LED.

3) No Pin 12

4) Pins 14, and 16 are for the HarDDrive activity LED. (Light)
Pin 14 for the Positive ( + ) wire.
If the HDD LED is dim when the Harddrive is active, switch the wires around.

5) Pins 18 and 20 are for the Power On switch.

6) Pins 1, 3, 5 and 7 are for an internal speaker. Used to hear BIOS Beep Codes.
Pin 3 is for the Negative wire ( - ), and Pin 7 is for the Positive ( + ) wire.

7) Pins 9 and 11 N/C. Not Connected. (External SMI lead)

8) Pins 13 and 15 are for a Keylock switch.
Some computers have a Keylock. Unlocked the computer will come on.
I -> believe, Not connecting anything to these two pins, is like having the Keylock in the unlocked position.
May be wrong. May have to have a jumper wire across these two pins for the computer to work.

9) Pins 17 and 19 are for a Message LED
(Sleep/Standby)

HOWEVER, the best method IMHO is to use an LED light, and touch two pins at a time, to see which ones are for the Power On switch.
When the computer comes on, (Power Supply), then you know which pins are for the Power On switch.

Computer running, do not touch those two pins again, and check the rest of the pins.
Computer turns off, and starts again? Restart switch
LED light blinks? Harddrive activity LED
LED light stays on steady? Power On LED.

Finding which two pins are for the Power On switch, also helps tell you where the rest of the pins are, by looking at the pinout on the HP Support page.

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=bph05159

Scroll down to Figure 4: Front panel connectors
Same Front Panel header used for this TriGem (Cognac) motherboard.
Clearer though.

Scroll towards the bottom of the page for the motherboard illustration, and photo.

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

In the illustration, and as the motherboard sits in your computer case, the Front Panel is at the Bottom/Right corner.
In the Illustration it is F_PANEL1.

In the photo it is the black rectangular block, with 9 contact pins.
Two rows of pins.
4 on the Top row, 5 on the Bottom row.

The pins on the Top row are numbered EVEN.
The pins on the Bottom row are numbered ODD.

Starting on the LEFT side on the Top row, going across to the Right;
Pins 2, 4, 6, and 8.

Starting on the LEFT side on the Bottom row, going across to the Right:
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED.
Pin 1 is for the Positive ( + ) wire.
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 RST SW is used.

C) Pin 9 is N/C.
Not Connected. Pin is reserved for factory use.

D) Pins 2 and 4 are for the 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.

Acer m464 front panel connectors


Sorry in the 1st instance for my lack of specific knowledge when it comes to ACER hardware.

Is the model of your MOTHERBOARD - Acer m464?

If so do you happen to still have a manual that came with the motherboard?

Sometimes you can see the pinout in white writing on the mainboard itself near the connector block... have a close look and see if it is there.

The pin out for the connector block will definately be in the mainboard manual. If you don't have the manual then you'll need to do a little searching for it... I'm sure a .pdf of it will be floating around... i guess start at the ACER site.

On the rack mount chassis, are the plastic chassis connectors grouped (ie. 2 wires into 1 connecter for pwr led, etc) or are they individual single pin connectors?

Either way for each group, one should have a little TRIANGLE on the opposing side to the writing. Conventionally this is your positive (+) pin when looking at the pinout diagram. Ensure you have correct polarity for all ur connections obviously.

See how you go mate.

JVC 8 pin pinout - speaker cable


Looking at the connector, there are 3 rows of pins.
Starting with the first row closest to the alignment mark:
[Power On],[Center Speaker],[Sub Woofer]
[Surround Right],[Speaker Ground],[Surround Left]
[Right],[Left]

If you are trying to connect two JVC units, you will need an 8-pin cable that has the SAME pins connected on each side. You will need to test this using a multimeter set to ohms or 'connectivity'.
There are other 8-pin cables out there like the one for apple networking, but they use a crossover pinout where pin 1 on one end = pin 3 on the other end. This is bad. JVC needs pin 1 to = pin 1.

This is a standard connector/pinout setup that JVC uses, so connecting a TH-C3 to a TH-C50 works fine. There is a bunch of intermixing that you can get away with. The only thing to keep an eye on is the power in watts that one unit sends and the other recieves. Worst case is that the speakers are quiter than expected or that you can turn the volume up so high that it can damage the speakers. In all cases, you should get desired volume somewhere on the dial.

If you are trying to wire the speaker set custom, then you will need to take note that an '8-pin' connector is actually a 9-wire connector. Along with the above pinout, you will need to add Case Ground, which is the metal circle that surrounds the pins. To make the speakers turn on, you will need to apply 12v to the Power On pin and ground the 12v source to the Case Ground outer ring.
The system takes 3 to 4 seconds to fully turn on after this connection is made. Speakers should be wired using the center pin for speaker ground and each other pin respectful to each speaker.
