Bypass the Power On switch. This will tell you if the problem is the Power On switch, or the Power Supply.
Has nothing directly to do with the Power On switch, or it's wires.

A jumper wire is used on the 24-pin ATX main power cable's connector.
Jumps from the green Soft Power On wire to ANY Black wire,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The preferred jumper wire is a paper clip.
The paper clip is straightened out, then bent into a U-shape.
The top of the U is wrapped a few times with black plastic electrical tape.
This tape area is for your fingers and thumb to hold onto.

Turning the U-shape upside down the 'Legs' are what is used.
One leg goes down into a socket hole with the Green wire.
The other leg goes down into a socket hole with ANY black wire.
ALL Black wires are Ground wires.

The BACK of the 24-pin ATX main power cable's connector, is where the wires go into it.
The leg of the U-shaped paper clip, goes down into the socket hole with the Green wire, RIGHT NEXT TO THE WIRE.

Right next to the green insulation of the wire.
The 'leg' has to go pretty far down in the socket hole.
It has to go far down in the socket hole, and TOUCH the metal terminal at the end of the wire.

The other leg of the U-shaped jumper wire has to go down into a socket hole, with ANY Black wire in it. It also has to touch the metal terminal at the end of the Black wire, down in that socket hole.

[All wires going into the 24-pin ATX main power cable's connector, end in a metal terminal,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

The Back of the metal terminal is the left side. The tangs on the left side, have not been crimped down on a wire yet. (Insulation)
The jumper wire touches this side.

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The Front of the metal terminal is the right side. The opening of the metal terminals, and Front side, can be seen in the middle photo of the Playtool link,


Power Supply plugged into power; 24-pin ATX main power cable plugged into the motherboard, as shown in the photo to the far right in the Playtool link above.

The contact period of the U-shaped jumper wire is Brief.
No more than 2 seconds. The Power On switch is a Momentary Contact Switch.

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.

For additional questions please post in a Comment.

REPLACED POWER SUPPLY AND MOTHER BROAD AND STILL CANT GET IT TOO POWER UP


I need you to check something first.
I'm going to get detailed here to explain;

1) The Dell Dimension 1100 (B110) uses a 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

The above is a STANDARD pinout for the wires going into a 20-pin ATX main power cable's connector.

For a time period Dell had parts made for their computers, that were PROPRIETARY.
(All pre-built computer manufacturers have their computer parts made by somebody else)

They were Proprietary, in that the STANDARD guidelines for desktop computers was NOT followed.
They had the wires changed around for the 20-pin ATX main power cable.

They also had the pins in the 20-pin ATX main power connector, on the motherboard, changed also.
Means if you plug in an aftermarket Power Supply, it may toast the motherboard, Processor, Ram Memory, Harddrive, graphics card, (IF used), and so on.

Fun stuff huh?
Dell changed from being Proprietary as far as I know.

However you computer may fall into the old proprietary parts.
You need to compare the 20-pin ATX main power cable's connector, of the old Power Supply, TO the new Power Supply's 20-pin ATX main power cable connector.

SEE if those wires (Color code) are going into the same socket holes, as the old one.
Look at the Lock on the side, and use it for the key.

In the Standard 20-pin ATX main power cable's connector, Number 1 pin is the Orange wire, and on the side OPPOSITE of the Lock.
Number 11 wire is also Orange, but is on the same side as the Lock.

Now you have the key, check out the old Power Supply's 20-pin ATX main power cable's connector.
Same color of wires going into the proper socket holes in the main power cable's connector?

Whew! Good! Let's go on.

You need to get the Power Supply going.

Bypass the Power On switch.

IF, you bypass the Power On switch, and the Power Supply comes on, you have a bad $5 Power On switch.

IF you bypass the Power On switch, and the Power Supply does NOT come on, you have a bad Power Supply.

Test has NOTHING to do directly with the Power On switch, or it's wires.
A jumper wire is used on the Soft Power On pin, TO ANY Black wire, in the 20-pin ATX main power cable's connector,

Looking back at the 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

The GREEN wire is the Soft Power On wire.
A-N-Y Black wire you see is a Ground wire.

(The power wires are Positive wires. ALL Black wires are Negative wires )

The preferred jumper wire is a paper clip.
Straightened out, then bent into a U-shape.
The top of the U is wrapped a few times with black plastic electrical tape.
This taped area is for your fingers and thumb to hold onto.

Turn the U-shape upside down, and the 'Legs' are what you are going to use.
One leg goes down into a socket hole with the Green wire.
The other leg goes down into ANY socket hole that has a Black wire in it.

The 'Leg' of the jumper wire goes RIGHT NEXT TO the existing wire in the socket hole.
Where the wires go down into the connector of the 20-pin ATX main power cable, is the BACK.
The 20-pin ATX main power cable is plugged into the motherboard, as shown in the photo to the far right, in the Playtool link.

The jumper wire goes down into the Back of the connector, and into the two socket holes named above.
The jumper wire MUST go far enough down into the socket hole of the connector, to go PAST the insulation of the wire, AND touch the metal terminal at the end of the wire.

All wires going into the main power cable's connector, end in a metal terminal,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

The left side is the Back, and the part that get's crimped on the insulation of the wire. The right side is the Front.
The Front of those Molex metal terminals can be seen in the center photo, of the Playtool link.

Contact made is no more than 2 seconds.
(The Power On switch is A Momentary Contact Switch)

Get the Power Supply going, then post back in a Comment, as to the results.

(Also make SURE the 4-pin ATX +12 Volt power cable is plugged in,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

This is power for the Processor, and sometimes forgotten. NO, it has nothing to do with why the Power Supply does not come on. Just wanted to add.

This is where it plugs into the motherboard,

http://support.dell.com/support/edocs/systems/dim1100/EN/SM/techov.htm#wp1061217

Processor and heatsink connector (J2E1) is where the Processor sits.
Processor power connector (J5B1) is where the 4-pin ATX +12 Volt power cable plugs in )

May I also ask why a new Power Supply was purchased, and a new motherboard?

My motherboard is getting power from a 450w smps coz the board LED gets on when I switch on the ups. But pressing the power button on the cabinet does not switch on the system. Please help!!!!


From your diagnoses you may have a bad Power On switch, or a bad Power Supply.

Reasoning?

An ATX power on switch is connected to the motherboard's Front Panel header.
From there the circuit is continued through the ATX main power cable, and into the Power Supply.

The Power On switch connects the Soft Power On wire, to Ground.
(The Soft Power On wire is abbreviated as PS_ON. The wire is Green)


If the Power On switch is bad the Power Supply will not turn on.


A bad Power Supply will have a weak voltage power rail, (Or more than one)
Enough power to light LED lights, and perhaps spin fans, but not enough power to turn the Processor on.
No Processor operating, no computer.

1) If all of the LED lights were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor can use from 51 to 125 Watts. Depends on what Processor it is.
(Older Intel Pentium III's, and comparative AMD processors used less than 51 Watts)

You may have enough power to light that LED light, but not enough to spin fans, or turn the Processor on.


There is a simple test to see if the problem is the Power On switch, or the Power Supply.
Bypass the Power On switch.

A jumper wire is used to temporarily connect the Soft Power On wire to ANY Ground wire.
The connection is made at the Back of the ATX main power cable's connector, with the ATX main power cable plugged into the motherboard, and computer plugged into power.

1) The Asus M2N-MX (And SE version) motherboard uses a 24-pin ATX main power cable.

http://www.asus.com/Motherboards/AMD_AM2/M2NMX_SE_Plus/

This is one example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Looking at the photo to the far right, shows the 24-pin ATX main power cable plugged into the motherboard.
This is the position for the test.
(Computer also plugged into power)

The BACK of the connector is where the wires go into the connector.
The jumper wire is used on the Back side of the connector.

One end of the jumper wire goes down into the socket hole with the Green wire.
(Soft Power On wire)
The other end of the jumper wire goes down into ANY socket hole with a Black wire in it.
ALL Black wires are Ground wires.

The jumper wire goes down into the socket hole RIGHT NEXT TO the existing wire.
The jumper wire MUST go down into the socket hole far enough to touch a metal terminal.

At the end of every wire going down into the ATX main power cable's connector, is a metal terminal.
The metal terminal is pretty far down in the socket hole.

The preferred jumper wire used is a paper clip.
The paper clip's diameter is small enough, to go right next to the existing wire in the socket hole, and touch the metal terminal.

The paper clip is straightened out, then bent into a U-shape.
The 'legs' of the U-shape go down into the two socket holes.
The middle is wrapped with a few wraps of black plastic electrical tape.
The taped area is for your finger, and thumb to hold onto.

The voltage is 5 Volts DC.
Two D cell flashlight batteries produce 3 Volts DC.
There may be a small spark when you make the connection, advising you in advance.

The connection made is no longer than 2 seconds.
(The Power On switch is a Momentary Contact Switch)

Computer comes on, (Power Supply actually) you know you have a bad Power On switch.
Computer does Not come on, you know you have a bad Power Supply.

I Need the jumper settings for the fic k8mc51g motherboard from a emachines desktop computer. Putting the motherboard in a custom case.


There is a 4-Pin Speaker connector that is not used by Gateway on the motherboard (right beside) the CMOS jumper settings (Pins).
The clear CMOS settings jumper block is right beside the speaker pins. You can use this jumper block to clear the CMOS RAM, which is powered by the onboard real-time clock button cell battery.
Pin 3 is indicated by the markings on the board.
Settings: Pins 1 and 2 covered = Normal Operation Pins 2 and 3 covered = Clear CMOS enabled.crazyeyes746.jpg

Yeah I have seen switches fail a few times, its rare though, trace the wire back to your motherboard and disconnect the lead, then short the pins. If it comes on replace the switch, if it doesnt reset the bios via a the jumper and try again, disconnect the long ATX cable from the mother board and all power connectors from peripheral devices and on the Long ATX connector that was connected to the motherboard you will see a green wire, connect your mains to the power supply and short the green wire on the ATX connector with the black wire next to it, the power supply should fire up, if it doesnt try a new power lead and outlet, if it still does not fire up its your powersupply. If however you power supply does power up you should reconnect everything and try your power switch and shorting power switch pins on motherboard again, if the power supply does not come on then yor motherboard should be replaced.

I assume you have tried with only one stick of ram individually at a time if you are using two to check it's not the ram as one faulty can cause the system to stop. Also assuming you bought the ram from the same place and is compatible with the board. Sometimes people also forget that the processor in some cases has to be powered by the 4 pin plug from the PSU and not just from the ZIF socket that older processors use to power up, so double check the manual. The other main common cause of the this problem is when you are putting together all the hardware onto the board, if you don't protect it underneath it may have overflexed the board and shorted or damaged the circuitry or the bios chip. That's not to say that the motherboard was'nt faulty in the first place.
