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.

so you have counted the flashes and the code says swap the wires??? I'm leaning towards another bad board because swapping wires isn't going to change anything and if it was wrong in the first place in doubting it would ever work.

In my experience you may need to replace the case but if you feel up to the challenge you can clean the contact headers on the MOBO for the PW LED and try reseting the CMOS for the bios.

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.

Will not power up, red light goes green flashes yellow then stays flashing red


Yellow lights and blinking red lights indicates general hardware failure on ps3. If your ps3 is still under warranty call Sony and they will send you a new or refurbshed one. Your ps3 is one in a billion (according to Sony). North America: 1-800-345-SONY (7669) United Kingdom: 08705 998877
Now you could try doing a few things (hey it's worth a try!)
1. Turn off the switch in the back and wait a few minutes. Turn it back on and try it again. If that doesn't work it may be dead.
2. You could try this article, if you choose to, it's a long shot but might work for you in your case. http://ps3.qj.net/Possible-PS3-flashing-red-light-fix-from-MXACE/pg/49/aid/75721

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.

If the power switch on the case is shorted out. (Not uncommon), you would get this kind of issue. There are other issues going on here. You should be getting a video display, from what you said your not. That is more of a concern. If you can borrow a PSU & swap yours out that would help. I see no need to buy one because that may not be the root cause for this system. You need to get video. There is a togel switch on the back of the PSU. You do not need to unplug the PSU, just click the switch. There also is a red switch on the PSU. Make sure it is set to 115v. Get back to me here after you try the swap. Best of luck!
