Question about Dell OptiPlex SX280 PC Desktop
My Dell Optiplex SX280 won't start up, when trying to power on the power button is just blinking yellow, seems like a power failure and I have tried with a power adapter from another computer that works.
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.
