Front panel USB connector

I plug in usb to front panel & it does (eventually) show up in "my computer" as removable disk "f" & sometimes it does not "kick in" but a few times it does take & i try to download music and it starts to download but then stop & says cannot download as it cannot find/ identify path. crazy part is i will plug in again (i have no idea what reboot is) & if it takes i will see music folder listed when i open "f" disk up but it will not play & then locks up & then no trace of usb flash stick can be found. am i missing some sort of software setup? thank you

First try plugging it into the motherboard USB on the back of the computer. Sometimes the front panel ones act up a bit. Then make sure the drive letter (f) is not in conflict with another device. You can actually change the drive letter in computer administrator.

Front 4 usb ports and microphone and headphone jacks don't work but the rear usb and speaker jacks do work. I've had the computer new since 2009 and they have never worked.


it sounds to me like the wires from the front panel connectors are not connected to the motherboard inside the computer case, open the case up find the front connectors wires inside and find out if there are any connectors on the motherboard to plug them into.
the reason the rear ones work is because they are soldered directly to the motherboard.
good luck.

P6610f motherboard


Are you following Anti-Static Procedures?

If you, or the person who took it apart has not, you can use the motherboard for a Frisbee.
(Processor for a neck trinket, and Ram Memory for Christmas decorations)

A) Let's start with the two power cables coming from the Power Supply, that go to the motherboard;

1) 24-pin ATX main power cable

Looking at the motherboard photo, the 24-pin ATX main power cable's connector; is at the bottom.
Two rows of 12 socket holes, in a yellowish/whitish connector.

Motherboard installed in computer case, you will find it to the Right.

(The motherboard view shown, is clocked 90 degrees to the Right; in comparison to how it actually sits in the computer case)

GENERAL example,

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

[NOTE* Color of connector does NOT matter ]

Note the hinged Lock Clip on the power cable's connector.
Also the TAB on the motherboard connector.
When power cable is deemed to be plugged in tightly, and properly; the Lock Clip will be over the Tab.

{Lock Clip operates on the same principle, as a see-saw on a playground. Top is squeezed in to release Lock Clip}

2) 4-pin ATX +12 Volt power cable

Looking at the motherboard photo, the motherboard connector for this power cable is;
Straight up from the white Processor socket,
To the right of the square finned Aluminum Heatsink.

General example of said power cable, and it's respective connector on the motherboard,

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

Has a Lock Clip too.
Remember about the color of connector, thing.
Can be pink with neon polka dots. Doesn't matter.
WHAT the power cable IS, does matter.

This power cable is power for the Processor.
It ain't plugged in, you have no computer.

(Scroll down to Motherboard Layout. It is PU521 )

That's it for power cables that plug into the motherboard.
Moving on..........

The Harddrive is a SATA unit. The optical drive is a SATA unit.
(CD/DVD drive)
Means you need a SATA power cable for each one of them.
General example,

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

Note the L-shaped opening in the connector. Hard to see in this photo, but I will show a better view in a minute.

Also; between a SATA data cable's connector, and a SATA power cable's connector; the SATA power cable connector is the larger of the two.
Has 15 contact pins.
SATA data cable connector has 7-pins.

Often there is a lock on this power cable's connector.
A tab that sticks up, or a 'bulb' type affair.
Depress with thumb, when plugging in, or unplugging.

Harddrive needs a power cable, and data cable.
So does optical drive/s.

B) General example of a SATA data cable, and it's respective connector,

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

Just referring to the cable shown at the top, for now.
Now you can see the L-shaped opening a little better.
See how the 'foot' of the L goes down? That is the direction you want it, when plugging in.

The motherboard connector shown below the SATA data cable, is a SATA connector.
This particular style is OPEN.
Your motherboard uses the type that is CLOSED.
Note also the L shape on the motherboard connector.

The connector shown for that SATA data cable, is a 90 degree bent elbow.
If your SATA data cables have this style of connector, they plug into the Harddrive, and optical drive/s.

The straight type of connector, plugs into the motherboard.
It can also plug into the Harddrive, and optical drive; if your SATA data cable has two straight connectors.

The SATA data cable connectors on your motherboard, are all the way to the Left. (In the motherboard photo)

Orange, Light Blue, Dark Blue, and White.
Note that they have a L shape in the middle.

Now scroll down the HP Support page, to Motherboard Layout.

Orange = SATA4
Dark Blue = SATA1
Light Blue = SATA3
White = SATA2

SATA1 is for the Harddrive
SATA2 is for an optical drive.
If you have more than 1 optical drive, it plugs into SATA3.

(Make sure SATA3 is ENABLED in BIOS Setup)

C) 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.

Looking at the motherboard photo, look again at the Orange SATA4 connector. To the Immediate RIGHT is the Front Panel header,

http://www.findlaptopdriver.com/n-alvorix-rs880-uatx-front-panel-motherboard/

I believe though, that the cable coming from the Front Panel; has one solid plug-on connector. Not individual wires.

Note how the Front Panel header on the motherboard, is missing one pin. This is the Key.
The cable connector going to it, should have one socket hole blocked off.

Should only be one cable coming from the Front Panel, that has the correct plug-on connector.
The other cables coming from the Front Panel, will have different size plug-on connectors.

Going further.........
Look at what is installed in the Front Panel;

USB ports, audio ports, (Headphone and Microphone), Card Reader, etc.
You can follow the cables, and get a pretty good idea of where they go, in the Front Panel.

For example you can follow the cables that go to the USB ports.
Follow the two cables that go to the Card Reader.
Follow the cables that go to Microphone, and Headphone jacks.

Then by process of elimination, you know which cable goes to the Front Panel header.

D) Front Audio
Looking at the motherboard photo, look towards the Top/Left corner.
The Yellow header is for the Front Panel audio ports.
Headphone, and Microphone.

E) Coming down the Left side, in the motherboard photo; look at the two White rectangular headers.
Match up in the Motherboard Layout, and bottom of HP Support page.

USB1 2, and USB1 2.

EACH USB header, is for TWO USB ports.

That is why they both have USB1 2 marked near them, in Motherboard Layout.

A Card Reader SHOULD use two cables, and One USB header.
It may be though, that the Card Reader will use both of those White USB headers.

Either the Card Reader plugs into them, or the USB ports in the Front Panel.
If the cable connector fits, plug that cable in. (On)

USB is USB.
Card Reader uses USB too.

Point?
If the cable's connector fits, plug it in. (On)

In the motherboard photo, there are two White connectors;
Above the Orange SATA4 connector, and Below the Light Blue, and White SATA connectors.
(Light Blue = SATA3, White = SATA2)

The USB ports up front probably connect to them. (Front Panel)
Follow the cables to Front Panel USB ports.
What type of connector do the cables use?

All FOUR of those USB connectors on the motherboard, may NOT be used.
Perhaps just two of them.

That doesn't 'sound' very concise, huh?
However it is my contention, that each cable coming from the Front Panel; should have a different connector.

Going further;
The Card Reader, and the USB ports in the Front Panel; may have the SAME type of connector, on the end of their cables.

Again, the Card Reader uses a USB header, (Or headers), on the motherboard.
So do the two USB ports in the Front Panel.

Therefore it does not matter which USB header on the motherboard, that either one of them are connected to.

F) Looking at the motherboard photo, look above the Ram Memory slots, to the far Right.

Right above ram memory Slot 1, that is White in color. (DIMM 1)
There is a small Electrolytic Capacitor, with a Black plastic sleeve.
Right above it is a small White 3-pin connector.

This is where the Processor fan plugs in.
(CPU_FAN)

G) Right above the square Aluminum finned Heatsink, is the 3-pin connector for the computer case fan.
SYS_FAN
(System Fan)

(The square Aluminum finned Heatsink, sits on the Northbridge chip.
Which is part of the motherboard chipset)

That about does it for me.
Please post additional questions in a Comment.

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)

For additional questions please post in a Comment.

1 Answer

My computer


1) The plastic panel on the front of your computer, is referred to as the Front Panel. (Some manufacturers deem it the Front Bezel)

The cables (Wires) from the Front Panel, connect to a Front Panel header on the motherboard.
A series of pins that stick up out of the motherboard.

The Front Panel header may be separated into two headers.

For most motherboards the Power On switch wires, Power On LED light wires, HarDDrive activity light wires, and Reset switch (If used) wires, usually go to just one of the Front Panel headers.

(If it is the style where two separate FRT PNL headers are used)

You have to locate the wires coming from the Power On switch, and see what pins they go to, on the Front Panel header of the motherboard.

Sometimes the Front Panel wires end in just one connector.
Sometimes these wires are separate, and each one plugs onto a separate pin, in the Front Panel header.

IF, the wires are separate, carefully remove the two wires terminal ends from the pins on the Front Panel header.

[POWER UNPLUGGED from computer. When you are ready to jump the Power On pins with a screwdriver, then plug the computer back into power]

Touch a metal flat tipped screwdriver, that the blade tip is just large enough to touch those two pins, (AND just those two pins), for the Power On switch.

(Inside the plastic Power On button, is a Power On switch.

This is a generic Power On switch for an example,

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

The contact you will make with the flat tipped metal screwdriver, will be a brief one. The Power On switch is a Momentary Contact Switch.

There will be a tiny spark. Hold the screwdriver by the insulated handle.
The Voltage is 5 Volts. (DC)
Two C cell flashlight batteries produce 3 Volts. (DC)

I want to show you a generic example of a Front Panel header.
The example I'm going to use is in a Gateway GT5408 desktop computer.

http://support.gateway.com/s/MOTHERBD/Intel2/4006160R/4006160Rmvr18.shtml

The white block with pins sticking up is Front Panel header.
Looking all the way to the right of this white block, and under the bottom right corner, you will see the number 2.

This designates that the number 2 pin, is all the way to the right, and bottom.

The bottom row of pins going across are numbered Evenly.
The top row of pins are number Odd.

The top row of pins are numbered 1, 3, 5, 7, and 9, and they start from the Right side, with the number 1 pin..

The bottom row of pins are numbered 2, 4, 6, and 8.
There is No pin 10. These pins also start from the Right side.

In the chart you will see that Pin 6 and Pin 8 are for the Power On switch.

That's the last two pins all the way to the Left, on the bottom row.

If your computer was a Gateway GT5408, these are the two pins you would briefly touch, with that flat tipped screwdriver.

If the wires that come from the Front Panel, (and it is the wires that contain the Power On switch wires), ends in a single block style connector, remove it from the pins.

Just ease the connector straight up, and off.
Now touch the two Power On pins with the screwdriver.

If I knew the computer manufacturer name, and Model Number of the computer in question, I MAY be able to give you a link, showing Exactly what pins to touch in the Front Panel header.

Barring that you jump the two Power On pins with a flat tipped screwdriver, and the computer does not come on;

I would advise using a jumper wire to bypass the Power On switch, to see if the problem is indeed the switch, or the Power Supply.

If the computer comes on (Power Supply starts), the problem is the Power On switch.
If the computer does not come on, the problem is the Power Supply.

This procedure has nothing to do with the actual Power On switch, or the Power On pins in the Front Panel.

You will be using a jumper wire on the 20, or 24-pin ATX main power cable connector.

(Again, I don't know what computer you're referencing to here. The computer could have a 20-pin ATX main power cable, or a 24-pin ATX main power cable)

This is an example of a 20-pin ATX main power cable, and it's respective connector,

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

The jumper wire is bent into a U-shape. It touches the green Soft Power On wire, and ANY black Ground wire.

There's more to it than this simple explanation. Should you desire to do this procedure, simply state so in a Comment. (Believe upper right of your page)

Lastly you could remove the harddrive out of your computer, place it in an external enclosure, and plug the external enclosure's USB plug, into any USB port on an available working computer.

This way you could retrieve your financial information, etc. now, and fix your computer when appropriate for you.

An external enclosure is a case that opens into two halves, generally.
The Harddrive plugs into an interface located with the enclosure.
(Interface. Simple explanation - Connector)

The enclosure is closed back up, and it's USB cable is plugged into an available working computer's USB port.
(Any open available USB port. Doesn't matter which one)

Again, I don't know what computer you have, so I don't know if it has an IDE Harddrive, or a SATA harddrive.

One example of a decent external enclosure, used for a 3.5 inch wide IDE harddrive,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1337265&CatId=2779

(Laptop harddrive's are 2.5 inches wide. Desktop harddrives are 3.5 inches wide. 3 and a half inches)

Usb ports not recongized


Hello,

Do use in the front ports, sometime this port is unplug to the motherboard so it need to connect before you can use that port. In the back port you can always use that ports in there it is safe to connect any plug and play device such as flash disk or usb port printer. if this both not recognize your any device you inserted then probably your device is dead. try insert your device to other pc to see if still working if not then maybe the driver of your pc are not installed. try reinstall all the driver of your system.

may this help.

You have 500mA on usb port. If you cause a short on usb connectors, this can damage the motherboard.
Disconnect usb port on motherboard (work with power unplugged ), remove all ide and floppy cable,eventually remove and put back in place bios battery and Ram.
Restart Motherboard only with 1 module Ram (bios battery back in place), CPU and Fan (ensure cpu and fan are well in place), do not plug anything else than switch on button.
If it still does not work there is a good chance you blew the Motherboard.
