Question about System Power Supplies

Test of Premium rating system process

RE: the Premium Question test

Can you log in with a different or borrowed board name and visit:

http://www.fixya.com/support/t1162878-test_premium_rating_system_document

to see all the input?

As you stated that you can only see one response at a time and then not go back to a previous solution: Do we like this paradigm? No. Quite frankly, I don't. This detracts the customer from the crowd sourcing model in the long run.

I believe the impetus to make change so the system is as it is now, was to deal with those experts who:
1.) were possibly using more than one board name to post
2.) experts who were quick posting with a one liner (not a valid assumption, as some problems require we ask for a model name, etc.)
3) experts using Place Holding techniques, similar to number 2

At the very least, the customer could have on a second page/tab screen or a pop up with a list of responding experts that are a link to that experts response. This would allow for 'going back' and re-rating an expert.

So, if the initial initiative was to calm down the waters for the customer so it appeared less overwhelming to them... this effort failed in part. That part being what I just wrote above.

To reiterate, giving the customer a flowing list of experts as links to their posts with the chance to in fact 'go back' to an expert and re-rate an expert, would be the single most change, for the better and have the most impact.

I won't go into details here, but programming a new window pop up or open a second tab or even initiate a floating frame on screen is not a difficult thing to do in web page script programming. You could get half a dozen of us volunteer to write the code for you.

We are all looking forward to the screen shots and the conclusive summary.

Regards,
Worldvet

I think it is the power supply. It is a Besttec ATX-200-12Z Rev D mounted in a Compaq 6450NX desktop PC running Windows XP Professional Computer will (intermittenly) start up, and shut down on it's...


Hello,

While it could be the motherboard it does seem more likely that it is the power supply.

Here are two options to test your theory:

1. If you have another known good power supply or can borrow one, hook it up to the motherboard and see what happens.

2: Or, if you have a known good motherboard or can borrow one (does not have to be the same as yours of course) hook your power supply to it and see what happens.

How can I test voltages on the Enermax Galaxy EGA1000EWL 1000-Watt Power Supply unit out of the computer.


Most motherboards will give tell you all of the voltages being provided by the power supply in the bios under hardware or health monitoring section. Otherwise you will need a multimeter to test the different voltages. You would want to set the multimeter to the 20v or similar setting. Depending on what voltage you would want to test would determine the color of wire you would check. You would connect the black/negative/ground lead of the multimeter to one of the ground wires coming from the power supply normally a black wire. The 12v is normally a yellow wire, the 5v is normally a red wire and the 3.3v is normally an orange wire. The wires may be different colors so you may want to look up the ATX pinouts to find the exact voltages you want to measure.

Can not get computer to power back up no lights on front o rear just little light on mother board have dell 8400


Bad Power Supply, sscorbett.

Usually you have enough power to light LED lights, (Like the harddrive activity LED light for add-in cards, that you see on the motherboard), and spin fans, but Not enough power to turn the Processor on.

Dell Support >Dimension 8400 > Service Manual

http://support.dell.com/support/edocs/systems/dim8400/SM/index.htm

Technical Overview > System Board Components

http://support.dell.com/support/edocs/systems/dim8400/SM/techov.htm#wp1052739

harddrive activity light for add-in cards (SCSI LED)

The Dimension 8400 comes with an ATX style of Power Supply, that has a maximum rated Wattage of 250 Watts.
1) ALL of the LED lights combined use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts
3) A typical Processor can use 51 to 125 Watts.

Your Power Supply just has enough power to light that LED light.
Weak voltage power rail.
Replace the Power Supply.

[ There are three power rails inside that SMPS.
Switched-Mode Power Supply.

1) The 3.3 Volt power rail
2) The 5 Volt power rail
3) The 12 Volt power rail ]

The ATX form factor for a Power Supply refers to the size, and shape of the case, for one.
Approximately 6 inches Wide, 5.5 inches Long, and 3-1/2 inches Tall.
The ATX power supply case in the Dimension 8400 however, is shorter in length.
It is 4 inches Long. (Depth)

Not an advertisement for the website, nor manufacturer.
Reference for the case size, and power cables needed,

http://www.cputopia.com/hp-400w-dell-dimension-8400.html

Scroll down to see the connectors of the various power cables needed.

You may have a Power Supply with these dimensions, and needed power cables, in an unused computer.
Perhaps someone has upgraded to a better computer, and has an unused computer that you can temporarily borrow the Power Supply for a test unit.

Make sure it has at least 250 Watts (Maximum rated wattage), plus,

1) 20-pin ATX main power cable. (Or a 20 + 4-pin ATX main power cable)

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

[ 20 + 4-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4 ]

2) 4-pin ATX +12 Volt power cable

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

Plus the various power cables needed for the Harddrive, optical drive/s, and computer case fan/s, if it/they do not connect to the motherboard.

MY POWER OUTLET TO THE COMPUTER KEEPS GETTING REALLY HOT AND MELTED AND MY BATTERY IS NOT CHARGING ANYMORE.


test the power outlet then

clean your computer of dust using a fine air blower from a compressor specifically around your central processing unit making sure there is no moisture in the air line

as dust will cause a lot of static which will make a computer overheat and cause lots of problems then test your computer battery or replace battery

hope this helps

My enermax power pack sparked out of the fan in the back and now my computer wont turn on. Not sure if it's the power pack or the board is fried... Any help would be appreciated thanks =)


if it sparked then something inside the power supply malfunctioned and that is the reason it wont work. You will need to replace it. Unlikely that it fried your board in the process. You can test this by swapping the power supply with one that you know works.

Emachines w3507 power


detarch all accessories or hardware connected to the system , then bring out the power pack itself out completely look for a soldering led to test the functionality of the power pack itself if it rotates the fan of its pack by looping the first hole to the third hole cable in the power pack connector that will head into the motherboard. therefore, check the mother board if there is any damage on it like some component if all this is false . then plug the power pack to the outlet and fix the connector of the power pack to the motherboard after detaching both cd drive , floopy disk drive leaving the hard disk and the memory . then change the memory card and press on the system there should be a solution from all this . the problem should be from the Memory not to be able to start up the system but go through those process i have given you before concluding it was the memory ok....


kindly rate this solution......

Printer Sharing for 32os and 64os


I am not sure I follow. If you are attempting to share a printer over a home network between computers with different OSes, perhaps you could try this:

If the printer works already with Win7(32bit), go to the Vista computer and try the following:

Go to Control Panel. Choose printer. Then choose Add Printer. Choose Add a local printer. Click on Create a new port. The default in the drop down box is Local Port. Do not change that. Click Next.

A dialogue box will appear asking for you to enter a port name. Type in the \\computer name\printer name

I have the same problem with Demension 5150. Replacing the P/S didn't solved the problem. When I connected the P/S the motherboard green LED light lighted up, however, no matter how many times I pressed...


For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives, other PCI cards. Do this one at a time until you find the culprit. If a POST screen, meaning you can see Anything from the PC brand name to Motherboard brand name appearing on the screen. The PC may not boot to windows, but it Does post at this point, and with that the problem is resolved. If windows does not load, then you have a new problem. Best dealt with asking a new question.

Good luck!

Gateway power supply


switching unit in powersupply sounds shot, if you want to test primary switching, un plug power from back, take main motherboard power socket off the board, take a paper clip and put it in the GREEN wire in the socket, and any BLACK wire, now (without touching the socket or having it touch anything else) plug power into the PSU, if the fans all fire up and spin, then the switching is fine, i would look at a fault on the board
