How to fix your dead Dell Optiplex-SX280

If the Dell Optiplex-SX280 doesn't boot anymore.
This means totally dead, only clicking sound from internal buzzer and blinking power button led.
Look to the "big" Capacitors top cap.
If they are pushed above you have to replace them.
Fixed, see below link

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.

IN dell optiplex sx280 model system we are using in this amber power led blinking continuly yellow color because of this not able to boot the system. kindly give the solution for the same


Hi there!

A blinking amber/orange light on the power button of your Dell Optiplex means a hardware failure. If you know how to strip down your computer to basic component, then I suggest you turn on with only the motherboard, processor, memory and PSU. If you are not familiar with this, I suggest you bring the computer to a qualified technician.

Hope this helps

Yellow blinking power button


A customer of mine has several of these that have the same problem. I found a comment on a Dell forum indicating that one of the capacitors on the mainboard will be either swollen or leaking. Replace the capacitor and it should be OK. I do not have the proper equipment for soldering on a mainboard so I have not done this. However, I did a google search on "Dell SX280 mainboard purchase" and I found a guy on ebay selling the repaired boards for $100.
