    What is the "PS" Do you Power Supply? If so why did you replace it?

    The refurbed power supply does the same indications: there is a yellow led on the mother board that is lite, the fan on the power supply does not turn and there are no beep codes. I was wondering if anyone knows a way to check it with a volt-ohm meter. I believe that these are switching power supplies and I seem to remember there has to be a load on this type of supply; but I don't remember if it is an inductive load or a resistive load. I get no beep codes and nothing comes up. Any help would be appreciated.

  • If the fan on the power supply does not turn on, then I think your Power Supply is bad. Why purchase a refurbished power supply when you can buy a brand new one for under $20 on ebay everyday?

  • Hey I just thought about something that I have run into on quite a few of the old Dell Optiplex GX series computers. In fact I just replaced the motherboards this week on a Optiplex GX150 and a Optiplex GX260.

    Remove the Power Supply, then open the case and take a flashlight and look all inside the computer at the capicators. They look like little batteries like the round AA or AAA but not as tall as those batteries. Anyway, look at them and see if any of them have any brown spillage coming out of them like corrosion. This causes the motherboard to go crazy and no matter what you do, it will not boot.

  • I misspelled CAPACITORS

    This power supply is a small form factor, so it has a higher price.. I have checked on eBay and since I am on a limited budget. I have opened the power supply and I know what capacitors look like and none of them were bulging or leaking. Thanks for taking interest and the suggestions!!!!

    I still need a method to check the power supply or the mother board. Details would be helpful.

    Thanks for the additional information... I worked for 25 years as an Electronic Tech.... but that was 12 years ago.... needless to say there have been a FEW changes (LOL). I have another power supply... the vendor was slow in shipping, so we discussed this and he sent another. I have not tried the last supply that was sent (It's a major pain in the tush!) I agree that it still looks like the refurbished power supply is the most likely culprit... Just trying to get a better understanding of of the problem. Thanks a lot for you help... I may go ahead and try the last power supply.

LOL, What do you mean still does not work? Does the computer try to come on? If not, the refurbished Power Supply is bad or the Motherboard is completely dead.

    No the system does not attempt to power up... no power supply fan running, led on mother board is lite... I need a way to determine which is bad.. the power supply or the mother board.. or a way to test to power supply.

  • I'm banking on your power supply is bad. You could take it to computer shop and let them do a diagnostic check for you and the cost to repair it. That should not cost over $30 - 40$. But it would be money well spent and in fact once they diagnose the problem they might waive a lot of it if you let them fix it.

    99% of the time when you plug that power supply in and hit the power button you should hear or see some sign that the power supply is working. Most times the fan on the power supply should kick in pronto. Normally and again 99% of the time why you have a mother board issue, if the power supply is working the board will give some kind of beeps or blinking lights.

SOURCE: Dell GX280 speaker problem..??

I have no idea why, but for some reason those speakers only work with the computer they came with.

We had the same speakers and decided to use them on yet another HP desktop. We can barely hear anything out of them...
My recommendation is to get a new speaker setup which has volume control separate from the keyboard. You can find a multitude of speakers at a great price here. Once the page loads use the menu to go to Computer Hardware>Speakers & Headsets.

SOURCE: SATA Hard Drive Type The Dell Optiplex GX280 Takes?


It makes no difference providing the computer motherboards support SATA interface.

SATA 1 and 2 drivers are in the BIOS. If all the computers have SATA 1 you can upgrade the BIOS to latest version via Dell's support website.

SOURCE: unable to power on a dell gx270. swapped ps with

Try jump starting it by shorting the power switch pins on the MB with a flat head screwdriver. If it starts then check the power switch on the case for loose connection. If it fails then replace the MB.

I am looking for a schematic for a Dell Optiplex GX280 power supply. The supply is model HP-U2106F3.

I just replaced my GX280 power supply (mini-tower) with the following 400W for $30.

The only place I can think you will find an actual schematic for the PSU is from the manufacturer.

Steady amber light unable to boot what should I do?

Your power supply has probably failed. I would say to use a power supply tester, but Dell power supplies have a proprietary setup; where a normal PS would light all the lights on the tester, a Dell PS will leave a couple of the lights off. that being said, I'd give 10-1 odds that that is your problem.

That being said, here are a couple of links; the first is for a how-to on replacing your power supply, the second is a link to a refurbished replacement for your PC.,g:RecentPopular,rk:&~lt=popup

Dell Optiplex GX280 - On power ON , no Fan movement no display

Confirm no leaking or bulging capacitors on your mothboard.
refer to here

As this was a common problem with the GX280.
If found, you will need to replace the capacitors.

The other check is to make sure the heatsink is fitted correctly, perhaps reaply the thermal paste if you have any. I know that high temps would switch the GX280 off.
