optiplex 320 solid yellow/amber power light

This question has suggested answer(s)
This PC is out of warranty, and from what I read, the problems I had of a dying system were either the power supply or the motherboard. Slight possibility of front panel board. I chose to replace the motherboard. It's all put back together the same way now. When I plug in the power cord, the power button lights up and stays orange/yellow/amber and fan does not start, etc. When first replaced motherboard and first started up, I did get a few seconds of fan and some beeps, and then it went down again... NO chance to check beep codes or anything. I have disconnected and reconnected all onboard cables, new battery, reinstalled memory. Power supply? Or throw in towel? Thanks in advance, Emily

  • Hi Emily,

    Are you getting anything from the diagnostic lights?

  • No, there are no other lights.

    The AUX led is on, on the motherboard, and the powerlight is on amber/orange/yellow as soon as I plug in the power cord.

    And I can press, or press+hold power button but nothing changes.

    Well perhaps I am losing my mind. I just unplugged everything and moved the computer, replugged everything and now get nothing at all when power button is pressed or held.

    Argh!

  • Symptoms are pointing to a power supply problem.

  • Seems like the power supply has failed.

    Its hard to say otherwise unless you test with a known good power supply.

  • Thank you - since I don't have another similar machine, I will order a power supply and replace it - I'll post an update after that!

  • Hello,

    Did you fix that PC then? Was it power supply or the front panel?
