Honestly I don't have much idea with this model, but I just wanna assist with what I can. When we look at the front panel connectors (9 pins) on the motherboard (generally on the bottom right hand corner nearest to the hard disk), we will be able see the labels like Pwr, Reset, etc.. (tiny texts) as shown below:
I have an older T1440 - 60ff93f.jpg

Plug in the corresponding connectors to the labelled pins, like Pwr-switch to Pwr and Gnd, Reset switch to Ground and Reset.. etc...

If you have problem with my instructions, let me know so that I can explain you with more details.

I hope this helps.

Good luck.

Thanks for using FixYa.

Hi


The wiring can be done using the similar kind of bus cable. To replace this you'll need to connect the new wires to the pins marked in the picture--

How can i start my desktop without front panel power button switch?


The power switch on desktop computers is a momentary-contact type switch. Pressing it makes contact and releasing it removes contact. Because of that, it would be impossible to wire up a situation where the unit will power up with power supply. Luckily, it is fairly easy to "replace" a bad power switch. If you open your desktop computer and observe the rear of the power switch, you will see two wires coming out of it They go to a plug that connects to two pins on the motherboard. You can purchase a momentary action single-pole switch at any Radio Shack. There is very little voltage or current to deal with so any light duty switch will do. With power remove from the PC, clip the wires you traced from the power switch (do not confuse them with the Power LED light) at attach them to the wires from switch you purchased. Apply power and test operation. After testing, you can make a small hole in one of the removable panels for expansion drives and mount the new power switch! It will work just like the original.

Just bought a Seiki TV and it won't turn on. I connected all the cables and plugged it into the wall socket, but it didn't turn on.


Have you switched ON its main power switch at control panel of the TV? Without turning it ON, you can't turn the power ON by it remote control.
Do the standby LED at the front of the panel lights up. If not check whether the switch I've pointed out here is ON. If the switch is ON and the power LED at the front panel do not light up, the fault is with its main power regulator board, inside. If so check and replace damaged component/s at it main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Do asearch by type in the brand name of your device at its search box.

It will be best to replace the power supply regulator board as card basis.

Need circuit diagram for HP m8100 GC673AA

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires connect to, is the Front Panel header.
(Power On switch, Power On LED, HarDDrive activity LED, etc)

The Front Panel header is Black, rectangular in shape, and is situated in a vertical position; located in the Bottom Right corner of the motherboard. (Next to the mounting hole)

It is a standard 9-pin HP Front Panel header,

http://h30434.www3.hp.com/t5/Desktop-Hardware/Getting-a-new-case-i-need-Front-Panel-pinout/td-p/842897

Scroll down to the 9-pin Front Panel header photo, and pinout.

The 4-pin side is the EVEN side. Pins 2, 4, 6, and 8. There is NO Pin 10.
The 5-pin side is the ODD side. Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light Emitting Diode, so it is redundant to call it a light)

Pin 1 is for the Positive ( + ) wire.
IF the HDD LED is dim when the harddrive is active, (IN use), 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. Reserved for factory use, and it is +5 Volts.

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.

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

Scroll the HP Support Motherboard Specification page down. Click on the + sign next to Motherboard Layout.

Left to Right on bottom edge of motherboard, Internal Connectors;

AUDIO_1 is for the audio ports on the Front Panel.
ATX_IN is where the small audio cable from the optical drive plugs in.
(CD/DVD drive)
IF TWO optical drives are used; the Main, or Primary optical drive, is connected with the small audio cable. NOT the secondary optical drive.

HD_AUDIO also connects to audio ports in the Front Panel.
May be mistaken, but don't believe SPDIF_OUT header is used.
1394A1 header is for the Firewire ports in the Front Panel (1394a)
USB 2 and USB 4 headers are for the Front Panel USB ports.
USB 1 and USB 3 should be for a Card Reader.

Need where the power cables go, and what they look like? Just post back in a Comment.

(Be SURE to FOLLOW Anti-Static Precautions)

How to replace power button


1) Unplug from power
2) FOLLOW Anti-Static Precautions

[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 BEFORE reaching inside your computer.

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.

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

Gateway Support > Gateway GT4010 Desktop PC > Main Support page,

http://support.gateway.com/us/en/product/default.aspx?tab=1&modelId=2809

Click on the Support Documents tab.
(Driver / BIOS / Applications / Patches / Support Documents / etc)

Click on the blue -> 5891 - Support Documents subheading
Click on Product Views.
Click on Rear View

Viewing the Front of your computer the Right Side Panel removes.
There are two Thumbscrews to loosen, shown by the letter C.
(They are supposed to remove all the way. If they do it's OK)

There is a finger-pull formed out of the back of the left Side Panel.
Pull towards the back of the computer. It should then swing out at the top, and can now be removed.

Go back one page, and this time click on - User Guides
Click on -

(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.
Took 10 seconds just now using a medium speed DSL connection)

Go to Page 51.
Now I would like you to go to Page 52 - Removing the front bezel

The Front Bezel is the Front Panel, of your computer.
It has 6 tabs that lock it on the metal frame of the computer case.
There are 3 of these tabs that you access, from the Side Panel opening.
It is only these 3 that need to be accessed, in order to remove the Front Bezel.

Looking at the inside, of the Front Panel, and the edge that meets the metal framework of the computer case;
One tab near the Top.
One tab in the Middle.
One tab towards the Bottom.

These tabs are plastic, and are formed out of the plastic Front Bezel.
Press the Top tab IN. (Not too hard or it may break)

Gently pull the Front Bezel towards the front of the computer, JUST A LITTLE.
Now press in on the Middle tab.
Finally press the Bottom tab in.

(Each tab has a flat hooked end. The tab itself goes through a slot, in the metal framework of the computer case. The tab must be pressed in far enough, so the flat hooked end will clear the slot, and allow the tab to slide through the slot; when the Front Bezel is pulled forward)

Tabs clear of the metal framework of the computer case; right side of Front Bezel swings out a little. (Viewed from the Front; Right side)
This will allow the tabs on the other side to release from the metal framework of the computer case.

NOTE*
It looks as through the Power On switch is attached to the Front Bezel.
This means use CARE, and ease the Front Bezel forward a little, away from the computer case.
Wires are still attached.

IF, you pull on the Front Bezel too hard, or too far; the wires may become unplugged from the motherboard.

IF, this happens, do not worry.
Here is the pinout information for all of those wires,

http://support.gateway.com/s/MOTHERBD/FIC/105553/105553nv.shtml

Click on Product Views.
For example; The Power On switch connects to the Front Panel header, on the motherboard. For this pinout click on -
W - Front Panel connector

9-pin header.
4 pins across the Top row.
5 pins across the Bottom row.

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

Starting on 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. It's a Light Emitting Diode)

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. 5 Volt check point reserved for the factory.

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.

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

F) There is NO Pin 10.

There is nothing(?) like removing a Front Panel (Front Bezel), and finding out you accidentally unplugged wires from the motherboard; and there is no pinout to connect them back.

Just makes you so HAPPY

Power On switch replacement:

The Power On Button is an assembly. Every pre-built computer manufacturer has their own design, and it can vary from MODEL to MODEL.

The main thing here is, the Power On switch usually doesn't.
This ATX power on switch is used in MANY models of Desktop PC's,

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

I know it's hard to see here, and I apologize for that. Best example I have found.
View what looks to be a metal square cap in the front of the view.
There is a small post that sticks out.

This post is what the plastic part of the Power On Button assembly, presses against.

Power On Button assembly may have a plastic post itself, which is returned with a coiled spring, once the Power On Button is pressed.
Or the plastic button itself, presses against that Power On switch post.

You need to soften the plastic of the Power On Button assembly, in order to remove the Power On switch.

The plastic tabs of the Power On Button assembly may break, if this is not observed. Also compounded by the fact, that the plastic of the Power On Button assembly, has been heated several times, and is now brittle. (Plus age)

I use a hair dryer set on low, (Thanks honey. I'll be right back with it, lol!), and slowly wave the nozzle of the hair dryer, back and forth across the Power On Button assembly.

Once the plastic has softened some, ease whatever tabs you need to gently move aside a little, to ease the Power On switch out.
Be aware that the plastic will cool almost instantly, and need to be softened again, before attempting to replace the Power On switch.

Or perhaps june_sells20 this is the best way to go,

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

There are two contact pins that the Power On switch wires connect to.
I would like you to jump across those two pins, and see if the Power Supply comes on;

Click on O - Front Panel Connector (Front Panel header)

Pins 6 and 8, which are the two pins in the Red areas, is for the Power On switch.

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

The above ATX power on switch is used a Lot.
It is inside the plastic Power On Button assembly.

If this is the correct style of Power On switch, and yours is bad, you can use a hair dryer to gently soften the plastic of the Power On Button assembly, and replace the Power On switch.

Do Power On switches go bad? Yes. A LOT.
Those who do not know how to diagnose usually wind up replacing the motherboard, or Power Supply.

For additional questions, or to have me clarify any of the above, please post in a Comment.

How to hook up the face plate of a emachine w3400 Wich includes 3 wires 1 power butten and 2 led lights


Look at the pinout of the Front Panel header, of the eMachine W3400's motherboard.

The plastic front of the computer is the Front Panel.
The area of pins on the motherboard, that the cables (Wires) from the Front Panel connect to,
is the Front Panel header.

The motherboard for an eMachines W3400 desktop computer is an MSI ms-7145
(Micro Star International)

Orient the motherboard in your view so that we are both looking at it the same way.
Processor to the Top, Ram Memory slots to the Right, white PCI slots (3) to the Bottom.

JFP1 is the Front Panel header.
(Junction Front Panel 1)

JFP1 is on the Bottom Right corner. There are two columns of pins arranged vertically.
(The JFP1 header runs parallel to the Right side of the motherboard)

The Left side column of the JFP1 header is numbered Odd.
Starting at the Top and going Down, the pins are numbered;
1, 3, 5, 7, and 9

The Right side column is numbered Even.
Starting at the Top and going Down, the pins are numbered:
2, 4, 6, and 8.
There is NO Pin 10

A) Pins 1 and 3 are for the HarDDrive Activity LED light. (HDD)
If the LED light is dim will operating switch the wires around

B) Pins 5 and 7 are for the Reset switch. (Reset button)
> IF Used

C) Pin 9 is Not used. (NC. No Connection)

D) Pins 2 and 4 are for the Power On LED light (If dim switch the wires around)

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

Trace the wires back to the Power On switch. Even if it means temporarily removing part of the Front Panel to see.

Same with the LED lights.
See which wires go to the Power On LED, and HDD Activity LED. (Harddrive Activity LED)

Follow the 3 wires, and tell me where they go to on the Front Panel.
USB port?
Memory Card Reader?
Firewire port? (a1394)

I have an emachines T1440 desktop. the front face of the machine is broken, the power cord, and the wires from the power cord to the power supply box. What type of case or tower can i use the remaining...


Luckily, eMachine uses a generic system board. You can purchase a case from any computer store. The only thing to watch for is the plate in the rear of the motherboard, make sure it matches your ports. Again I believe you can use the one from your eMachine.

Desktop won't start.


Try to replace the power supply with another known working power supply from another P4 desktop and then reconnect your wires from the front panel led lights, changing them around until they are in the correct position. I had an almost similar problem and I did the above, it is working now. All the best ! sirjohn
