Question about Dell OPTIPLEX 960 MT Desktop Computer (Intel Core 2 Duo E8400 250GB2GB) (BO5SC306)

1 Answer

My Optiplex 960 flashes amber 3 light when powering on.

Unit flashes amber 3 light and does not power up. This usually indicates Motherboard issue. Whats unusual is if I press the power supply test button the system will power up and be usable with no obvious issues, until powered off. Then the issue of power button comes back.

Hey, have you ever thought that you ANSWERED YOUR OWN question? If you press the power supply TEST button, then it powers up fully? It's NOT the button.......So...what else could it BE then Mitch?

"power supply seems to be working?" If you had before this happened a issue where had to turn it on a few times to get it up---suspect bad caps in power supply---A look inside that will tell you if this is the issue or not. If the supply can be removed (most can) it can be examined or tested by most repair shops for little or nothing.

see attached photos of what bad caps look like in case you remove the supply to look at it.

Optiplex 960 number 3 blinking


The #3 light is an indication of a processor problem. You may have a bad cooling fan, or a poor heatsink connection, or just a failing processor. The fact that it resets makes me think more along the lines of a fan issue. Here is a list of the codes and what they mean:

Hi, on most Dells a flashing amber light on the power button indicates a problem with the PSU or a short on the main power rail, if this is the case you should have 2 flashing lights as well, 1 & 3.

Why is dell optiplex 780 lights 1 & 3 ok and power button amber?


An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard.
Remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Del 320 optiplex orange lite blinks won't boot up



For the Optiplex 320, a flashing amber light with no sound indication can mean 3 things.


1) Your power supply has failed

2) Your motherboard failed, most likely from a bad capacitor.

3) The front panel board (where the power button is located) is faulty or not connected properly.


I've worked with 10's of 1000's of Dell Optiplex's over the past 8 years and the flashing amber light is well known as a tell-tail sign of one of those three failure. Always start your trouble shoot with a PSU tester, then inspect the motherboard for domed or split/leaking capacitors...then on to the front panel which would require another panel and ribbon from the same model.

We have around 30 units of DELL Optiplex GX280 having mother board failure. It was more then 3 years old already. Once the turbo fan become noisy then it will gone dead.


May be serious. See if the power light goes amber after power up. I had (have - still siting in my basement) one that did same. Power up, fans sound like 747 taking off. Power light goes and stays amber. This is USUALLY caused by bad capacitors on the mother board. Known GX280 problem going back. If you look on the motherboard, the capacitors should have flat tops and not leaking. If the are rounded or leaking, the MB has probably gone bad.

I obviously can not be 100% sure about this as the unit is not here.

You can google "gx280 solid amber light loud fan" and see the issues. Here is one such link.

I have a Dell Optiplex 210L when i push the power button a solid amber light appear.. thanks any suggestion


Click here to visit dell support. The documentation provides details about the light codes and diagnostic procedure.

I think it is a power issue, which is usually indicated by amber light on dell systems. I came accross dell systems with similar indication and the issue was improper voltage either due to faulty power supply or bad connection.
Therefore, i suggest that: -
First, make sure that the connections and voltage to your system is proper.
Also, get the power sully unit checked by a professional for its proper functioning. I may require repair or replacement.

Let me know if any further clarification is required. Hope this helps!

My optiplex 330 is not powering up.the power botton flashes orangy bright when the pc is turned on.what the problem there please


The common issue related with a Flashing Amber Power Light is a BAD POWER SUPPLY. If the Amber Light is SOLID then it may be your MOTHERBOARD.

But if it is flashing repeatedly then it is your power supply, you will need to purchase a new one. Good Luck.
