Solved!
Go to SolutionOptiPlex 9020M will not turn on
Hello,
We have two OptiPlex 9020M. One is fine, the other is problematic.
Pressing power button does nothing. No beeps, no lights. Have to unplug power lead, wait 10secs, plug back in and try again. Multiple presses of the power button will eventually turn it on.
Dell have replaced the motherboard but same issue remains.
Could it be the power supply adapter? It's external to the PC.
We have a logitech USB nano receiver plugged in along with monitor via DP. And use another USB port to recharge logitech K&M.
Thanks

Hi Boyderama,
Thanks for the post! The problem you describe could certainly be related to the systems power supply. I would suggest swapping with the known good second system to test. When testing make sure to remove all external devices, it’s possible an incompatible or failing external device could also interrupt the power up process.
If the system reacts the same with no devices attached and using the known good AC adapter I would suspect a power button or internal component to be the cause. If you’re comfortable doing so, check the power buttons cable connection and make sure other internal components are well seated.
