Question about Dell OptiPlex GX270 PC Desktop

Power on/boot-up problem

Flashing yellow light when try to switch on. Have tried swapping PSU but no change. Problem built up over a few months. Would take a series of boot-ups to get going - each time 'holding on in there' a little longer before crashing. No error messages just a hanging system, blank screen, etc. Nothing to do but switch off and start boot up again! Then stopped completely, apart from flashing yellow. Am happy pulling it apart and testing stuff. Also have a couple of derelict PCs which I can rob for leads, etc to test

Have I got a story for you? Dell inadvertently used some defective capacitors in their Optiplex motherboards and some power supplies. From what I?ve experienced and read this affects the Optiplex 270 and early 280 lines. In my case my systems had video display problems and eventually ended up not booting. The giveaway is looking at the large 150 uf capacitors; they are the larger ones usually with an ?X? inscribed on the top. If the tops of the capacitors are flat you?re out of luck but if any of them are bulging (even slightly) at the top, leaking electrolyte or split Dell will replace the motherboard for free. This program is in effect till 2008. I wouldn?t recommend pulling the power supply apart but the flashing yellow power light for me has been a failed power supply. I would check out the motherboard for bad capacitors then call Dell. It?s likely they will replace the power supply if it?s in warranty, perhaps even if its out in light of the capacitor issue. If you?ve got some rounded caps on the motherboard I would also ask them to replace that as well. Let us know if you have any other questions and please don?t forget to rate this posting.

Computer will not turn on....how do I check to see if power supply is faulty? I have power supply removed and have a tester to check for dc voltage etc


I just went through a heap of troubleshooting with power supply issues before swapping psu's and finding this was the solution to my problem. Had a closer look at my psu that was faulty, the green light was flashing on the psu, unplugged all components and thought that I now had a non-flashing green light on my psu, on closer inspection the light was actually flashing very fast so appeared to be an almost solid light...the psu was stuffed so replaced it and no more issues. If your power supply has a green light check to see if it is flashing when plugged into voltage with nothing connected to it. If it is a solid light then it is probably ok.

Dell Inspiron Vostro 530s won't boot.


Hi,

I work for Dell, If the power button led light is flashing amber or amber (the Power supply is faulty) The Yellow light you saw inside the motherboard is the "Flea Light" (that is one way you could check if there is still power on the motherboard). Since the motherboard was replaced there are a few more things to check:

1. Video card (integrated or expansion)
2. Monitor (Make sure it displays self test feature when the cables are removed)
3. Monitor Cables (VGA / DVi)
4. Power Cable on the Monitor (try a different cable)
5. Power Supply (you already checked, but i suspect this is causing the problem)

Hope this helps.

I put this tower in the corner for a few months, board lights up but no video (on board) when turning on, no signal message on monitor ,tried a pci video card and still nothing Worked fine prior to...


Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes Pc

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

Fujitsu Siemens Scaleo 600. No power to processor.


Probably a PSU failure, although it could just be your power switch. Try shorting the power switch connections on the motherboard, if that doesn't work, replace the PSU with a standard ATX PSU. They're relatively cheap.

A bad Power Supply Unit (PSU) does not necessarily mean no power, just not enough power to run the computer. You can try swapping it out with another one of equal or greater output watts.
If after swapping it out you still have the same problem then you may have a failed motherboard then. Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. The dead giveaway will be the fact that you are not getting anything after you changed the PSU. There are a few companies that will repair broken capacitor issues. Also if you add a bunch of extra components without upgrading the power supply you can suffer underpowered situations and that can cause internal parts to fail.
To eliminate some other stuff you could remove the memory and disconnect all the power plugs from the drives and then try to start it up. If it does not change the behavior at all (no beeps, no change in flashing lights) then you probably have motherboard issues. Make sure when disconnecting the memory chips (sticks) that you touch the metal on the inside of the case first to discharge static electricity. If it does change the behavior add 1 component or item back at a time to see what you can find out. Post back with what you find.

A power supply or mobo can be flaky and fail some times and not others. And since she stated that she has had problems before, she can't blame you! From the conditions she described it sounds like a failing psu or mobo. Let me know what you find out. Also for curiousity sake what processor are you running?

Pover up trouble


sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?
