Dell gx270 power and orange flashing light

Hi, hope all is well in your part of the world.

I have a similar issue as a post you have, in regarding the orange flashing light issue on Dell Gx270's - Did holding it in for 10secs (the power button) resolve the issue permanently? Or did the unit completly fail soon after anyway?

When i got back into the office today, one of our training rooms, which have these (second hand) Dell Gx270's had been put in the I.T room by our I.T lead administrator, with a note saying the psu was dead.
I am familiar with the capacitor issue with the Dell Gx280's (as both of these we had failed in quick sucession).

After opening the case (to inspect the capacitors) I started the unit which booted to windows fine. I was some-what surprised at this, as our Lead I.T is a geek guru, there isnt much I.T related he is ever wrong about or cant fix.

So after having the unit on for about five minutes I was thinking of shutting it down, I was doing other tasks at the time, when the next thing i know there is the Dell with the orange flashing power light (and how i found the post).

I have restarted and left four office apps open and an antivirus trying to get it to fail again, like a makeshift burn in wizard, and am currently typing this from the unit with a "dead psu" - which obviously isnt the case.

I am also wondering if you have found any knowledge, in your troubleshooting travels of these Dells that might be helpful, do they intermittently fail or they generally fail and thats it? Reason being that it isnt worth putting time into putting the unit back into production especially if its only going to fail again / soon. Or issues like there is just to much dust in the fins of the cpu and its overheating and shutting down because of the "speed step" technology that these cpus are supposed to have.
Any advice would be greatly appreciated.

Thankyou in advance

P.S
I didnt try the option of holding in the power button for 10 secs. As I havent had to try this option yet - I dont whish to introduce other elements into the equation until / if required.

Hi Mikeabcde,
I'm not sure how much help I can be in this matter. When I had the problem of a dead PC, showing only the orange flashing light, I was unable to do anything with the machine. As nothing seemed to work except the light, I randomly decided to (a), just push in the button for less than a second (which did nothing, then (b), hold the button in for 5 - 10 seconds, which immediately resolved the issue. Afterwards I talked to my son who is quite a guru in these matters, and he told me that this was "standard procedure" for resetting this machine. I had gotten into trouble when I was reconnecting a CD burner power supply while the PC was on.
I believe my machine is a 2004 model, which had been "refurbished" I have to say that I could find no evidence whatsoever of any refurbishing - it looked brand new in every aspect. In researching online, there does appear to be a capacitor problem with this model, although I have had no such problem in over a year of use. I don't believe that overheating is a major issue with the Dell GX270. I have never known dust in the CPU fins to cause excessive overheating. Obviously, if the machine is located in a way which would prevent reasonable ventilation around the case, overheating might then occur, but this would be unlikely.
Replacing a bad capacitor might be a solution, although it might be difficult to identify the problem cap., since they can go bad without any visible indication. Replacing the power supply unit is a possibility, but the cost might not be justified for this relatively inexpensive machine. Good luck, Mike. Hope everything works out successfully for you Have a great day!

I am willing to modify your exhaust fan to give it better cooling if it is possible, but I need an exhaust fan sent to me to modify. I currently sell cooling fans on the web that I manufacture. Since this seems to be a large scale problem from Dell, I want to see if I can create a fix. It looks like the cpu overheats. Either a bigger fan or better cooling system.

I think you may have problems on your motherboard and / or power supply unit.

Everyone knows about the problems with bad capacitors, but they might not know the following:

1. They are in the power supplies just as much as in the motherboards.
2. There may be no visible signs of damage, but still be bad capacitors.
3. The problems these capacitors cause may show themselves intermittently (they come and go).

The "fix" for these is to replace each and every electrolytic capacitor on the motherboard and power supply. The motherboards have between 25 and 30 capacitors themselves.

Alternatively, you can fix the motherboards and just get new power supplies if you can find them.

If you go to this web site: http://www.badcaps.net/

You can read all about the problems and fixing the motherboards yourself if you like. They also offer a motherboard repair service as well. It's cheaper than throwing them away, or buying a new motherboard and they offer a warranty too.

They don't currently have fix it kits for power supplies, but maybe soon.

All I can tell you is that I've dealt with tons of these and in most cases, the power supply is bad too and they can "appear" to work fine at times, and they go nuts at any time. It's the nature of the capacitor problem. However sometimes they do "blow" and won't work again.

Good luck!

Orange light on D


Ha! We used to have loads of these - if I recall, it was a network adapter error - otherwise, check the motherboard for blown capacitors, they'll be bulging or even spewing yellow gunk out the top. This was a very common issue and Dell should replace the board free of charge.

From my experience orange power button usually means 2 possible issues. One is motherboard especially if it is model gx270 or power supply issue. Unless you really know what you are doing it will kinda be hard to determine. You can open the case and look on the motherboard to see is there any capacitors that look cracked or bloated(not perfectly round) which would indicate motherboard issue. I would take it to a pc repair shop if it is worth it and have the test it. Good luck.

Can anyone tell me what the orange light on the power button means? I am using a Dell GX270 and the PC will not start. You can power it on but nothing happens.


If you are getting an orange which we call in technical terms amber colored light it means that your PC required either the power supply to get replaced or the motherboard (Blinking amber or steady amber) both are guiding towards the same issue. It is better you first check it with the replaced power supply if not then motherboard is the sure shot solution

Orange light on Dell GX270 power button


A solid orange light, usually indicates an internal power problem but just in case try reseating the memory. Also its become a habit on a GX270 to check the capacitors to make sure they aren't bulging.
