Question about Gateway DX4822-01 Power Supply 575 Watt Upgrade
Time to diagnose Mike.
See if the problem is a Power On switch, or the Power Supply.
The procedure is to use a jumper wire, on the 24-pin ATX main power cable's connector.
Photo of motherboard,
Click on the image of the motherboard to enlarge.
Look at the top/middle edge, and between it, and the ram memory slots.
There is an opaque white connector with 24 socket holes.
This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,
Look at the photo to the Right. Power cable plugged into motherboard. See the Green wire?
That is the Soft Power On wire. Abbreviated as PS_ON.
You are going to briefly jump it to ANY Black wire.
ALL Black wires are Ground wires.
Does not involve cutting on any wire's insulation.
A straightened out paperclip bent into a U-shape, is the jumper wire.
The top is wrapped a few times with black plastic electrical tape.
This taped area is for your fingers to hold onto.
Turn the U upside down, and the 'legs' are what is used.
Power Supply plugged into power, power cable plugged into motherboard;
Where the wires go down into the power cable's connector, is the BACK of the connector.
One leg of the U-shaped jumper wire goes down into a socket hole, with the Green wire. Goes down into the Back of the connector, and right next to the insulation of the Green wire.
Has to past the insulation of the wire, and MUST touch a metal terminal that is connected to the end of the wire.
(About 3/8ths of an Inch)
[Every wire going down into that power cable, ends in a metal female terminal that resembles this example,
Looking at the photo in the middle of the Playtool link, you can barely make out the tip openings of these female metal terminals. Look like to be brass ]
The other leg of the U-shaped jumper wire goes down into ANY, socket hole that has a Black wire in it.
The contact time is to be no more than 2 seconds.
The Power On switch is a Momentary Contact Switch.
Power used in the Soft Power On circuit is 5 Volts DC.
In comparison two D cell flashlight batteries store 3 Volts DC.
There MAY be a spark. Advising you ahead of time.
You may wish to use a glove on the hand that holds the jumper wire.
IF, the Power Supply comes on you have a bad Power On switch.
IF, the Power Supply does Not come on you have a bad Power Supply.
You can lay the computer on it's side, opening of computer case up, so that it is easier to work on.
You SHOULD follow Anti-Static Precautions, once you have opened the computer case.
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static before working on your computer.
Computer on a table, 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.
Also clean out the inside of the computer. Use a can, or two of compressed air for computers. (Computer UNPLUGGED from power)
The Power On Button is an assembly. The Power On switch is a separate unit, and contained within the Power On Button assembly.
MOST of the time this ATX power on switch is used,
The plastic of the Power On Button assembly is probably pretty brittle. Heat and age over time has made it so.
I use two methods to soften the plastic enough, so that tabs do not break when trying to remove/replace the Power On switch;
1) The Power On switch has been deemed to be bad. No need to worry about it's condition now, it's going in the trash.
So I fill a bowl with as hot a water as I can stand, and dip the Power On Button assembly in it, holding onto the wires.
Plastic softens then begin.
2) Use a hair dryer, and constantly keep the nozzle moving back, and forth across the Power On Button assembly.
For additional questions please post in a Comment.

If the electrical outlet does not work , plug the product into another outlet that does work.
If the electrical outlet works, but the product still does not turn on , continue to the next step.
Solution two: Make sure the power supply is compatible with the HP product
The term power supply refers to both the power module and the power cord.
NOTE: To make sure that your product and power supply are compatible, HP suggests you use the original power supply shipped with your product.
Example of a power module Example of a power cord
NOTE: The power module might have a permanently attached power cord, or the power cord might detach from the power module.
Make sure the voltage and amperage specifications printed on the power supply match the voltage and amperage specifications printed on the HP product.
Voltage and amperage specifications printed on the power supply Voltage and amperage requirements printed on the HP product
If the voltage and amperage specifications between the product and the power supply are compatible, make sure the connector on the power cord is the same shape and color as the connector on the HP product.
WARNING: Do not force a power cord into an HP product that is incompatible with the HP product (different shape or size).
If the power cord is not compatible with the product, replace the power cord with a compatible cord. To buy a compatible cord, right-click the following link, How to Buy HP , and then click Open in New Window .
If the power cord is compatible with the product, but the products still does not turn on, continue to the next step.
Solution three: Reset the power module and test the power
Step one: Reset the power module
The power module has a safety feature inside that protects the product during a power surge. If you experienced a recent power surge, the power module might need to be reset. Use the following steps to reset the power module.
Unplug the power supply from the rear of the product.
Unplug the power cord from the electrical outlet, power strip, or surge protector.
If the product uses a power module with a detachable power cord, disconnect the cord from the power module.
Wait 15 seconds.
Reconnect the power cord to the power module.
Plug the power cord back into the electrical outlet. Do not use a power strip or surge protector.
Check to see if the power module has an LED.
If the power module does not have an LED, continue to the next step.
If the power module has an LED, check to see if the LED lights up.
If the LED does not light up, contact HP to replace the power module. To buy a compatible power module, right-click the following link, How to Buy HP , and then click Open in New Window .
If the LED lights up, continue to the next step.
Step two: Test the power on the All-in-One
Follow these steps to test the power on the product.
Reconnect the power supply to the rear of the product.
Press and quickly release the Power button to start a Power On/Off cycle. Do not hold the button down.
Figure 1: Press and quickly release the Power button
If you press and hold the Power button too long, the product might turn on and then off without restarting. If this happens, press and quickly release the Power button again.
If these steps resolved the issue , there is no need to continue troubleshooting.
If the issue persists , see the next step.
Solution four: Test the power with a compatible power cord from a different product
If you have another available power cord that is compatible with your product, use the alternate cord to repeat the steps in Solution three: Reset the power module and test the power .
If the product turns on with the alternate power cord, the original power cord caused the issue. Contact HP to replace the power cord. Right-click the following link, How to Buy HP , to buy a compatible power cord.
If the product does not turn on with the alternate power cord, continue to the next step.
Solution five: Service the HP product
If you have completed all the preceding steps and are still experiencing a problem, service the product.
