blinking amber power light & amber aux led on motherboard Optiplex 755

This question is not answered

After a recent severe storm, even though my computer was plugged into a UPS / battery backup, I have a blinking amber power light and amber aux power light on the motherboard.  Can someone help me diagnose which part needs to be replaced?  Thank you

  • Hi rjlyle,

    I would suggest you to drain the residual power from the system:

    • Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer
    • Disconnect the power cable from the system tower.
    • Press and hold the power button for 10 seconds

    If this does not work then the issue is with the system motherboard and you may need to replace it.

    Please feel free to reply for any further assistance. I will be glad to help you.

    Thanks & Regards
