First, did you make sure it was plugged in? Does it power up in anyway other than the switch on the front? if so and you are certain it is the switch, they are easy to fix, find the model number usually on the front of the tower, go to the manufacturers web site and either email them or contact them thru the support page, tell them the model number and ask how much the switch is. Usually less than 20 dollars and sometimes you can find a universal one at your local radio shack.

Gateway DX4822-01 power switch problems


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.

Main wires such as Power On LED, Power On switch, HarDDrive activity LED, and Reset switch; IF used.

Suggest KEEP track of where those wires go!

Make a drawing, and notes. I even use a magic marker, (Sharpee?), and make a notation of the Front Panel header pinout, on the floor of the computer case.

In this particular case it isn't known if the Power On switch is the problem, or the Power Supply.

Power On switch;
Power UNPLUGGED to computer, Anti-Static Precautions FOLLOWED; (Don't know? Post back in a Comment),

Remove the twisted pair of W/B and W/G wires, to the Power On switch pins, in the Front Panel header.

Plug power back into computer.
Use a small flat tipped screwdriver, and touch the two Power On switch pins. (Jewelers screwdriver works well for this application)

Power Supply comes on? Bad Power On switch.
Allow Windows to fully load, run for a few minutes; then turn the computer off normally.

Jump the two Power On switch pins again.
Power Supply comes on? You DEFINITELY have a bad Power On switch.

Power Supply does NOT come on?
We will go to a further diagnostic test then.
Awaiting results for first test, then we will go on.

Front panel connections


I don't find the Front Panel header pinout online, nor do I have an MSI MS-5191 in the shop.

I would suggest using one the LED lights with two wires.
(3-wire is a dual color LED)

There are two rows of pins. Usually the Power On switch, Power On LED, and Speaker; are on the same row.
HarDDrive activity LED, and Reset Switch are on the opposite row.

Speaker has 4-pins designated for it. All the others use 2-pins.
(Unless the PWR ON LED is a dual color jobbie)

Touch two pins next to each other, in the same row; with the 2-wire LED.
Start with finding the Power On switch first.

Usually the top row 1st two pins are Power On LED (Light)
Next in line are the 2 pins for the Power On switch.
Bottom row 1st two pins are usually HarDDrive activity LED (light)
Next 2-pins are usually Reset switch.

May not apply to a motherboard old enough to use a Socket 7 processor socket.
There may be 18 to 20-pins.
Bear in mind that many are not used, and probably 4 are for an internal speaker, for hearing BIOS Beep Codes.
May be two separate Front Panel headers.

Once you find the two contact pins in the Front Panel header, for the Power On switch; I would put the Power On switch wires on.
The small pin connector on the wire/s, will keep you from accidentally touching these two pins again, when the computer is on.

Now you have the two pins for the Power On switch, and the computer is running; then keep touching 2-pins at a time with the LED. (Light Emitting Diode)

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

Look for abbreviations near the pins in the Front panel header.

PWR, Pwr, Pwr On, Sw, and SW; are just some of the abbreviations for the Power On switch.

HDD LED, and HDD are two for the HarDDrive activity LED. (Light)
(If it states HDD SW it is the Power On switch. Weird old way of marking)

RST, Reset, and RSW, are for the Reset Switch.
(Reset Button)

If you see 4 pins marked with a bracket ( [ -> Turn so it's horizontal), these are for the internal speaker.

Type MSI front panel connector in your search bar, and look at -> images. See if you can find an image of your MSI Front Panel header pinout.

You can bet MSI carried out that Front Panel header pinout, on other MSI motherboards, besides the MS-5191.

The MSI MS-5191 may have been a motherboard made by MSI, especially for a pre-built computer manufacturer, and not listed on their website as an OEM motherboard.
(Original Equipment Manufacturer)

Won't have the Front Panel header pinout, listed on MSI's support website. (Doesn't)
But you can bet there IS an OEM motherboard made by MSI, that the Front Panel header DOES match.

May be different expansion slots, or motherboard chipset, or whatever; but the same Front Panel header pinout.

My power switch on gateway desktop, GT5404 does not turn on it only flashes briefly then goes off.


Suggest;

1) 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 unplugged from power 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.

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;

Gateway Support > GT5404 Desktop PC > Main Support page,

http://support.gateway.com/us/en/product/default.aspx?tab=1&modelId=2916

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

Click on -> 1009371 - Support Documents

Click on Components in the list.
Scroll down to the Motherboards subheading.
Click on the blue -> 4006158R - Intel (Coryville) 945G Motherboard

In the list click on Product Views
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.

Normally the front panel on/off power button and the front panel reset button plug into connector pins on your motherboard.

If you can find a User Manual for your motherboard it will show you exactly where the switch leads plug in on the motherboard. The motherboard's manufacturer and model number will be printed on the board somewhere.


Good luck.

The Power On switch is located inside the plastic Power On button assembly.

It is a Momentary Contact Switch, and is named an ATX power on switch.
This ATX Power On switch I have found fits many computers,

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

Tell me the manufacturer name, and Model Number of the computer, or tell me the manufacturer name, and Model Number of the motherboard, and let me see if I can find a Pinout for it's Front Panel header.

Have emachine T1150 - the on off button when pushed in is getting stuck and machine will no longer turn on. Can this be fixed and is it worth the cost ? Can I fix myself ?


The switch on the outer plastic front panel is usually just a plastic peice with a spring, it pushes the button in on the inside metal housing of the computer case, therefore not really much to worry about, you just need to remove the front panel to free up the plastic so it dose'nt get stuck in the hole, this is normally just caused through dust or resadue build up from your fingers when turning the computer on and off.
To get the front panel off you will have to remove the side panel, have a look to see if there any screws holding the front panel on, if not then it is just held on by expansion clips that expand with inserted into the metal houses of the case, just gentle ease away from the inner housing.
When you have removed the front panel just fiddle with the switch a bit and try to free it up, whilst the front panel is off you could try pressing the button on the front metal housing to ensure the computer does turn on.
when you have done this just replace the front panel and and put the case back together and you should have solved the sticky switch problem.

Turn the computer display-side up with the front toward you.
Open the computer as far as possible.
Lift the rear edge of the switch cover and swing it forward until it rests on the keyboard.

Release the zero insertion force (ZIF) connector to which the LED board cable is connected and disconnect the cable from the LED board.
Remove the switch cover.

Now remove the panel directly above the battery compartment and remove the 2 keyboard screws there and another 2 screw in the battery compartment (they should me marked with icons of keyboards)

Turn the computer display-side up with the front panel towards you.
Open the computer as far as possible.
Lift the rear edge of the keyboard until it rests at an angle.
Slide the keyboard back to disengage the tabs on the front edge of the keyboard from the top cover.
Swing the keyboard forward until it rests on the palm rest.

I press the power switch on my Acer Aspire RC900 and PC shows up on the screen on the harddrive, however the computer won't boot. When I press the power button to turn it off, it won't switch off.


if it wont continue on the booting operation it may be a problem in your memory module.. try cleaning it first... and when you can switch the power on but cant turn it of you should look in the function panel (the pins on yuor mobo where your front panel is connected ) and check if the front panel connection is correct, if its correct your mobo is more likely to be grounded on the casing.
