SOURCE: I purchased a Gateway DX4822-01 with an Acer

this is your standard front panel configuration. the wires from the case should have different colors for positive and negative. the colored wired is usually positive and the white typically negative. please refer to case manual for clarification. you can also test to make sure this is where the power switch location is by "jumping it" with a flat head screw driver. i would do this to verify the location first. again this is simply the standard configuration and i can't guarantee that your board is set up this way.

hope this was helpful.

Well of the 4 things needed for a pc to power on and work, you have replaced two. Next would be the mother board or CPU so if you have spare parts to test with I would try those.

This motherboard Adam?

Can't help you.









OH, I'm just KIDDING!

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

On the motherboard the Front Panel header is marked as PANEL1.
Scroll the page down, until you come to Motherboard layout.
Click on the + sign to the left of it.

Shows an illustration of the motherboard.
Bottom/Right corner is PANEL1. The black rectangle that is sitting vertically, in the motherboard photo.

Motherboard installed in computer case, the Front Panel header is two columns of contact pins.
FOUR on the Right side, FIVE on the Left side.

I don't know the actual numbering of the pins, so I'm going to number them myself;

Starting on the Left side at the Top, going down,
Pins 1, 3, 5, 7, and 9.

Starting on the Right side at the Top, going down,
Pins 2, 4, 6, and 8. There is NO Pin 10.

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. If not, do not connect to them.

C) Pin 9 is N/C. Not Connected. It was a +5 Volt power for the factory.

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

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

F) NO pin 10, just a blank spot.

How to find out what wires are what, in that Front Panel harness connector?

Follow the wires from the connector, up to the Front Panel.

Front Panel removed it is easier to see where the wires go.
You can follow the color code of the wires, and see which twisted pair go up to the Power On switch.

You can also see which ones go to the Power On LED.
(Light Emitting Diode, so it is a light)

Reset switch, (IF there is one), same thing.

The only pair of wires that will be left is the HDD LED wires.
HarDDrive activity LED.

The 9-pin plug will have to be CAREFULLY cut apart. Separate the wires, AND their metal terminals. (WATCH your fingers!)

For additional questions please post in a Comment.

Manual for 41t-ad motherboard


http://www.skyline-eng.com/index.cfm?fuseaction=product.display&Product_ID=8665

Bottom/Right corner of motherboard - Front Panel header. Take an LED with two wires on it, and touch pairs of pins. ( 2 )
When you briefly touch the 2 pins that turn it on, you have the Power On switch wires.

Do not touch these pins again, and test the rest of the pins.
LED stays on? You have the Power ON LED pins.
LED blinks? You have the HarDDrive activity LED.
Computer restarts? Restart switch pins.
Some pins do nothing, 4 in a row may be for speaker, some pins have +5 volts, and are not used either. (Factory use)

Power front panel conectors on acer 915m08


This Foxconn 915M08-G-8KS motherboard made for Acer Veriton desktop computers?

http://www.sella.co.nz/general/computers/components/motherboards/other-motherboards/b1jnj6/

Do not know what the Front Panel header pinout is.

(Front plastic part of computer tower is the Front Panel.
Area of contact pins on the motherboard, that the wires (Cables) from the Front Panel connect to, is the Front Panel header )

CAN see by clicking on - View full size image - that the Front Panel header is to the Top Left corner of the motherboard, by the CMOS battery.
(View of mobo is upside down, in relation to how it actually sits in the computer tower case)

Shows me it is just the normal two rows of contact pins used in a LOT of desktop computer mobo's. (MOtherBOard)

If it were I, I would use one of the LED lights connected to two wires, and touch across each two sets of pins.

Looking at the motherboard as it sits in the computer case, there is a row of pins on Top, and a row of pins on Bottom.

In your mind start at the LEFT side of the pins at the TOP.
Number them from Left to Right.
Example, Pins 1, 3, 5, 7, and 9.

Now number the pins on the Bottom, from Left to Right,
Pins 2, 4, 6, 8, and 10.

Computer plugged into power, touch the two wires of the LED light, to Pins 1 and 2.
Computer doesn't start? (Power Supply turns on)
Go to the next set of pins.

I am willing to bet Pins 5 and 6 turn the Power Supply on.
No? Keep experimenting.

What will happen if you touch the WRONG pins?
N-O-T-H-I-N-G
You will NOT hurt the motherboard.

When you get to the correct pins, the Power Supply will turn on.
These pins are for the Power On switch.

Now go back through the pins with the Power Supply on, but DO NOT touch the pins that turned the Power Supply on.

When the LED light STAYS on, you have the pins for the Power On LED light.

If the LED light BLINKS, you have the HarDDrive activity LED light.

If Windows starts to load, and you touch the Restart switch pins, the computer will restart over again, and Windows will load again.

(IF this computer has a Restart switch. I do NOT use one, even for the older computers. Just press CTRL, ALT, and DELete keys at the SAME TIME, to restart the computer, or use the Task Manager option)

One pin left all by itself? That is for 5 Volts, and only used by the factory. Leave it unconnected.

There may also be a blank spot on the Front Panel header, where it looks like a pin is missing. This is the KEY pin, and is not used.
It is just to orient where the other pins are.

Worried about getting shocked?
There may be a small spark, as you connect the wires, I will gramnt you that.
But the voltage is 5 VOLTS DC.
In comparison two D cell flashlight batteries produce 3 VOLTS DC.

The harmful AC voltage is contained in the metal enclosure, of the Power Supply. Can't get you unless you pour water on it close up, or stick a metal rod through one of the ventilation holes, in the Power Supply enclosure.

Regards,
joecoolvette

By the by. You could be a lot of people's hero, if you came back, and posted the pins for what they do. Post in a Comment.

I have motherboard Compaq #277498-001 and can't find power sw


Not sure of your particular MB, but most always the switch is a pair of pins in an array where the front panel LEDs and reset and power switch are.
This array of pins is almost always at the lower right hand side of MB. Assume the components side is facing you and the expansion slots are at your left hand, (where you add extra cards like video etc). then look at the lower right side or bottom edge, mostly right at the edge of the board. Should be an a double row of pins, at least 8 maybe up to 12. Look real close next to these and you may see print indicating which pair do what. PS = power switch. RS = reset, HD = Hard drive LED PLED = power led light.Spk internal beep speaker etc. (Note LEDs require correct polarity to work) Sometimes no print there.. Then you need the manual to decipher pin pairs. Or experiment. All you need to do is make the connection momentarily (like push button) with a small screw driver tip to start it, while looking for correct pins.
If no power on check your power supply connections on the MB. Or suspect either MB or Power supply issue.

Motherboard won't fire up processor fan starts then stops. new power supply, new CPU. No change. Home built computer. Stripped memory, circuit boards,drives except floppy. Reset cmos. No change.


even though its new could still be bad processor, power supply, or the motherboard its self.try to jump it without the power connected. should be pin 4 and 6. double check that though in your manual.jump it with a wire but dont touch any other pins or you will fry the MB.

Can not find where to put the PWR S/W on MB


look on the mother board for a group of pins, two rows, the top row will have one less pin then the bottom row. right next to the missing pin is the two pins needed for your power switch. touch a screw driver to one of those two pins one at a time and that will tell you which one is pos.

Connecting front panel wiring to INTEL 845GRG Motherboard


Hello davideiker1, the Intel D845GRG MB manual is shared with another Intel board. (D845GBV MB). Go to this Intel site & download the D845GRG manual; http://support.intel.com/support/motherboards/desktop/d845grg/sb/cs-008873.htm You'll need Adobe reader to view the manual. Download Adobe from this link; http://www.adobe.com/products/reader/
See page 9 for motherboard layout.
The front panel connectors are shown on page 68, see item C.
On page 69 is, Table 31 shows the pin assignments for the front panel header. Front Panel Header (J9G1).
Pin 1 is power for the hard disk drive led, pin-3 is negative for the hard disk drive. Wire colors coming from the case are important. Look at all of the front case wires. The common color for each 2-pin connector will be ground. In most cases the ground wire is white, except for the internal speaker. Ground for the speaker is normally black. (This motherboards speaker is built into the MB, no hook up is needed).
Pin number 2 is positive for the case power led which lights up as green. Pin 4 is negative for the power led.
The reset switch is a bit different. Pin 5 is negative & pin 9 is positive, however if your case uses a two pin connector than connect pin 7 as ground & pin 9 for positive. The On/Off switch, pin 6 is positive & pin 8 is negative.
If this manual is not what you see on the MB, please advise.

Good luck davideiker1!

Hi sivaprasanna,
Do you still have your manual? If so turn to page 72 for location.
For a close look at the motherboard front panel led to MB pins look at these two pics.
Location of front panel connections;

f111d01.jpg
Item " A " is the front panel MB pins.

Pic two is the layout for each front panel connection;

4db3155.jpg
The power on jumper uses pins 7 & 8.
Pin 7 is positive & pin 8 is negative.

Good luck sivaprasanna!
