How to start up a power supply type P1G-6300 which was part of a computer.I suspect there were some switches which are no longer connected to the unit

It seems that there were some signals and/or switches in the micrcomputer which this unit was powering.Now I would like to use the unit as stand alone power supply and the unit would not run.

You can test the power button. Remove the wires from the power on pins on the motherboard. Momentarily jump the two pins with a small screwdriver. If the computer starts the power button is bad. If it still doesn't start then something else is wrong. Did you test the memory? Also do all of the fans work, especially the CPU fan? It can't hurt to test with the other PSU. You know the HDD is good. Test one piece of hardware at a time and hopefully you will find the problem.

SOURCE: computer wont start up. Blinking green light in the back of tower

I've had that happen twice to my Vaio desktop and there was a very easy fix. I'm not a techie, but I found a recommended solution online when this first happened six months ago. I couldn't find the solution again, but I fortunately remembered the steps.

Remove the side pane to access your motherboard cables, etc. Locate the connector on your motherboard that contains the wires going from your power supply to your motherboard. It will be a large, rectangular connector with a lot of individual wires It is not a ribbon cable but should be located next to a ribbon cable connector andnext to a geen blnking light on your motherboard (when the power supply is plugged into the wall). Note: This green blinking light is in addition to the green blinking light on the back of the PC.

This next step is important: You have to disconnect the connector noted above from the motherboard WHILE the power suply is plugged into the wall. Wait a few seconds and plug it back in. The blinking reen light on the motherboard should now be a solid green light. The PC should now power up.

It worked twice for me; I hope it works for you.

SOURCE: Dell Dimension 8200 does not power up.

1) It could be something as simple as the 4-pin ATX +12 Volt power cable isn't plugged into the motherboard.

The 4-pin +12 Volt power cable supply's power to an Intel Pentium 4, and above, processor.

Looks like this,

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

The connector can be Black or White in color. However, there will always be two Yellow wires, and two Black wires.
(Yellow is 12 Volts. Any Black wire is a Ground wire)

Looking at the motherboard with the Processor to the top, Ram Memory to the right, and the AGP graphics card expansion slot, towards the bottom.

The connector for the above power cable is white in color, and square shaped. (May be Black) It has four socket holes in it.

This connector is located in-between the Processor, and the AGP slot, towards the I/O ports on the motherboard.

This is Dell Support, and the Service Manual for the Dimension 8200,

http://support.dell.com/support/edocs/systems/dim8200/

On this main menu page left-click on - Technical Overview

Scroll down the page to the second illustration. (Under the heading - System Board Connectors and Sockets)

Where the arrow that points from, + 12VDC power connector (JC51), is the connector on the motherboard for the above power cable.

2) It could be something as simple as the Ram Memory modules, or module, has been jarred loose. (Ram memory 'Stick')

3) It could be that the Power On switch has failed.

There is a way to bypass the Power On switch to test if the switch is bad, or not.

This has been lightly touched upon already, but not fully detailed, and not in a safe manner.

There is always 5 Volts present at the Power Supply. When the 5 Volts are redirected to the Soft Power On part of the Power Supply, the power supply turns on.

The 5 Volts are redirected by the Power On switch. (Located behind the Power On button)

The Dell Dimension 8200 Desktop PC uses a 20-pin ATX main power cable connector.

This is a close up view of that style of connector,

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

View the photo to the far right. You will see a Green wire. This Green wire is the Soft Power On wire.

You will see many Black wires. ANY Black wire is a Ground wire.

If a jumper wire is touched briefly from the Green wire to Any Black wire, the power supply will come on.
(Provided the power supply is good)

The contact of the jumper wire, should not last any longer than 2 seconds.

There is a Spark involved, which is why safety guidelines should be implemented!

Advise using a wire that has insulation around it. Wire thickness, or gauge, should be close to one of those power supply wires.
Length approximately 3 inches.

The insulation is stripped back off of each end of the wire. Usually about 1/2 inch stripped off, will do.
The jumper wire is then bent into a U shape.

The jumper wire has to go in the socket hole of the Green wire, and Any Black wire.
The 20-pin main power cable connector remains connected to the motherboard. Just like in the photo to the right.

The photo to the right shows the back of the connector. The back of the connector is where the wires enter.
The front of the connector is plugged into the motherboard.

The jumper wire goes down in the socket hole, from the Back of the connector.
The bare wire ends must be long enough to touch a metal connector, that is way down in that socket hole.

My method:
Computer unplugged from power.
I twist both bare ends of the jumper wire until they are tight. One end goes down in the Green socket hole. I try to make sure it is a good connection, and will stay there by itself.

Then I plug the computer into power, and push the other end of the wire down into a socket hole, of ANY Black wire.

You just need a momentary contact.

4) For a time period Dell was a Proprietary computer manufacturer.
They wanted THEIR computer parts used in THEIR computers.

They switched the color code around on the 20-pin ATX main power cable connector.

A) Yellow is 12 Volts
B) Red is 5 Volts
C) Black is a Ground wire
D) Orange is 3.3 Volts
E) The Green wire usually designates the Soft Power On wire.
(PS_ON....Power Supply_ON)

Look to see that the color code of your new power supply ATX main power cable wire, match that of the old Dell power supply.

Would appreciate hearing about your findings. You can post this in a Comment.

Samsung 793S (Black) 17


On these older CRT monitors when you have that type of problem it indicated that the high voltage power supply is not putting out the right voltage to charge the picture tube. As the power supply gets weaker the time to show a picture will take longer and longer. It is not worth repairing the unit because parts will run much more than a replacement monitor.

Tip

UNINTERRUPTIBLE POWER SUPPLY


UPS – UNINTERRUPTIBLE POWER SUPPLY
Uninterruptible power supplies provide protection against mains power faults to computer equipment.
These faults include voltage spikes/interference, over voltage and under voltage, mains supply interruptions and surge protection etc.
These faults can cause computer and electronic equipment that are connected to an unprotected mains supply to malfunction and/or sometimes fail.
A common problem, when burning Cds, DVDs etc. any slight power interruptions to the burning process will halt the recording process and rendered the disc useless.

There two type of Uninterruptible Power Supplies
The lower powered and cheaper type UPS are switch-over types, when the mains supply fails, the UPS switches over to the batteries and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.
NOTE : The mains waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).
The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and then the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

My dell dimension computer won't turn on. When I push in the button, it only flashes orange and then won't turn on.


Plug the computer into a power strip that has an on/off switch. Turn the power strip on. Press the computer power on button to start as normal, but after after one second turn off the power strip switch just long enough for the fans on the computer to slow down, but the amber computer led doesn't turn off and then turn the power strip switch back on. Computer should start and run fine. Computer typically can be shut down for up to 5 minutes and restarted normally--any longer and you have to sue the power strip power switch routine again

My computer does not recognize it. It used to work, but now it won't do anything when I put a cd or dvd in it. It also has the light scribe feature. It only came with Nero cd, no intstallation cd.


I devised these simple steps that tend to remedy quite a few common USB problems.
.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability.

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again.

If you suspect a cable NEVER get one longer than the one you want to replace

If you checked and fixed anything there and still have issues it may well be due to the device itself or a weakened usb port, a loose usb port.

To remedy the last two consider a new usb card if it for a PC

Monitor will not turn on including power switch


I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.

There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.

I would check your fans first , a failed cpu fan will cause the computer to overheat and not start.then cables, add-in cards and memory to be sure ones not halfway in it's slot.. then i would suspect the power supply, they can be missing power on a rail and still have a light on the back. you can buy a power supply tester at tigerdirect for 20 dollars. once all this is checked , i would look to the motherboard..
hope this helps in the decision making process..

No power


Most times when this occurrs, there is a problem with the power supply inside the unit. It is possible that the motherboard is not telling the power supply to turn on. Any time the computer is plugged in, the power supply provides 5V as a standby voltage. Pressing the power button sends a signal for the remainder of the power supply to start up. If the 5V supply is not present, no action will occur. Try replacing the power supply.

You need a new power switch. I am currently working on a S4020WM with the same problem. I cut one wire to the power switch, then used a paper clip to make a jumper to start the machine. It has run fine since then. The only trouble I am having is finding a replacement switch.
