A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, 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.

Optiflex sx280 does not start.


Fans working? Maybe a PSU failure? Replace CMOS Battery. Reseat/replace Memory Mods. It's getting a bit old. Hard to say with a older computer thing start to go one by one. I replaced a PSU after 7 years. CMOS battery dead, replaced, Then the Sound Failed, new sound card. etc. I stripped it of useful parts and sent it out into the world.

My computer is blinking orange light


In addition to the power supply, motherboard issues can cause the blinking power light and no boot problems. The Optiplex 270, 520, 620, 745 and 755 units are all known to have issues with capacitors on the motherboard. Here is a link to an article about this issue and what to do about it:

You need a start-up CD and re-flash the Bios to Factory settings that worked. Best guess would be something was wrong with the BIOS package you had installed or someone/something messed up the installation which is causing your problem.

If you have factory CD Try to start the computer with that in.
