Replacing a power switch on a gateway tower


The plastic front of your computer is the Front Panel

Slip this off to access the Power On Button assembly, which has the Power On switch inside it,

Outside view,

Rear View,

-> FOLLOW Anti-Static Procedures -> BEFORE reaching inside, your unplugged from power, computer.

Now look at the Rear view of the Front Panel again.

The LEFT Side Panel removes.

Looking at the Rear view of the Front Panel; note that the LEFT side of the Front Panel, is towards the Bottom.

See the three TABS sticking up along this edge?
One at the Bottom, one in the Middle, and one at the Top.

Flat plastic TABS formed out of the Front Panel itself.

Another point of view.......
The metal framework you see that the CD/DVD drive/s are in, is the Optical Drive Bay.

Look at the Optical Drive Bay, and towards the Top/FRONT.
See that flat TAB sticking in from the Front Panel?

Now come down to the Middle of the Front Panel.
See how out at the bottom of the Optical Drive Bay, there is a TAB sticking in from the Front Panel?

See the TAB at the Bottom?

They hook on the metal framework of the computer case.
They go through SLOTS in the metal framework.

The Tabs are pressed to the Inside of the computer case, OR to the outside of the computer case.

This action brings a hooked end on the end of the TAB, to the Middle of the slotted hole it\'s in, and then the Tab is free.

Suggest start with the Bottom TAB, press on it when hooked end is free of slot; then do the same for the Middle TAB.
Now perform this on the Top TAB.

The TABS are pressed to the inside, or to the outside, and pressure is put against them towards the Front Panel.
Push on the Tabs, to push the Front Panel away from the computer case.

Once all three TABS are free, the Front Panel will swing out, and remove.

Power On switch is mounted to this metal case,

Me?
I would open that case, and take the Power On switch itself, out.
Then see if I could find a replacement, or one that I could live with,

How does the switch wires get placed


On an Intel D945GTP mobo? No prob!

I would like you to download the User Manual, (Motherboard Manual)
This way you will not only have the Front Panel header pinout, you will also have other needed information for the future.

However, in case for some reason you are unable to download the User Manual, I will post the connections also.

[ The plastic front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the cables, from the Front Panel go to, is the Front Panel header ]

http://www.intel.com/p/en_US/support/highlights/dsktpboards/d945gtp

On this page under the bold subheading - Documents and Guides -
left-click on the blue -
Product guides for D945GNT and D945GTP.
(Don't believe we can use the Ampersand on here)

On the next page left-click on the blue -
Intel Desktop Board D945GNT/D945GTP Product Guide - English (PDF)

[ Disregard the following if you are aware;
This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
{I would suggest upgrading to Adobe Reader X version, if your computer does not have it }

At the top of the PDF file { Header }, is the PDF file page number box.
If you know the page you want, you can use the Down Arrow to slowly arrive at the page you want,

Or,
1) Put your mouse cursor in the page number box. Left-click once.
2) Type the page you want.
3) Press the Enter key

The Zoom In icon ( + ) increase the view size.
The Zoom Out icon ( - ) decreases the view size ]

Go to Page 13. This shows a Top View of the motherboard.
It is clocked 90 degrees to the right, in regards to how it is actually sitting in your computer case. (In your mind turn it to the left)

The letter O indicates the Front Panel header.
Turned as it should be mounted in your computer case;
1) It is a rectangular block with two rows of pins.
2) It is under the SATA headers on the motherboard.

The Front Panel header is color coded.

A) The two pins in the Red block are for the Power On switch

B) The two pins in the Green block are for the Power On LED (Light)
IF, the Power On LED is dim when the computer is on, switch the wires around.

C) The two pins in the Purple block are for the Reset switch, IF a Reset switch is used.

D) The two pins in the Orange block are for the HarDDrive activity LED.
IF, when the harddrive is active the LED is dim, switch the wires around.

E) The pin all by itself next to the Purple block, (Reset switch) is N/C.
Not Connected.

How to bypass power button on dell gx150


See http://support.dell.com/support/edocs/systems/opgx150/en/ug/about.htm#inside for a view of the internal connections for the Dell GX150 motherboard and front panel connector.
You would need to try to identify which wires on the front connector pin block are used for the power switch then use a meter to check whether the switch makes a temporary or permanent connection between those pins to know whether you could just jumper them or not.

Nissan maxima 2004 power lock sticking unable to unlock the car with the remote or the internal switch. some doors will unlock but the driver side and front passenger will not. sometimes the rear door are...


If you live "up north", I would be suspecting rust or corrosion inside the door mechanisms.
You should be needing to take all 4 door panels off, all the whilst remembering that the clips holding the door panels on may be plastic and are very easily broken.
You might need to take the inside door mechanisms apart and lubricate them.
Be sure to use a lubricant that will not evaporate or wash off with water.
I like silicone grease for this.
God bless your efforts.

My hotpoint washer does not turn on


There are four components to check if your washer will not turn on at all. You need to check your power supply, the door switch, the cycle selector switch and the timer motor.
Am suspecting the power supply, Your dishwasher may not be receiving any power. It is somewhat difficult to check for power at the plug outlet because the plug for a dishwasher is usually behind the unit. You should make sure all the circuit breakers of your circuit breaker panel are in the correct positions, or check to make sure no fuses of your house fuse panel are blown.
That should do the job for you. Hope this helped you.

An incomplete red ring circle appeared


Three flashing red lights around the Xbox 360 power button (nicknamed the "Red Ring of Death" or "Red Lights of Death" or "Red Ring of Doom"), instead of the one to four green lights indicating normal operation, represent an internal problem that requires service. Warning signs may include freeze-ups, graphical problems in the middle of gameplay, such as checkerboard or pinstripe patterns on the screen, and sound errors, and the console only responds to pressing the power button to turn it off. These events may happen once or several times until the hardware failure occurs, or not at all. If the console freezes occasionally, the error will not necessarily follow. The technical problems seem to affect some generations of consoles more than others. e.g. Xbox 360 60GB This error code is usually caused by failure of one or more hardware components, although it can indicate that the console is not receiving enough power from the power supply, which can either be due to a faulty power supply or if the power supply cable is not fully inserted into the console. The 3 flashing lights can also be caused by power surges; if the console is connected to an outlet that receives a power surge, it may have a failure and the 3 lights will appear as long as the console is plugged into the outlet. Turning off the console, unplugging all power cables and plugging them back in, and restarting the console will fix the issue in this case.
