In this tutorial, you will get a reference guide about the Dell OptiPlex Desktop PCs. The guide gives you the reference and shows a list of the diagnostic LEDs and Beeps that are built into them for diagnostic use during a No POST situation.
The Dell OptiPlex 5040 came to use with Not Turning On situation but the Power LED was still in blinking state showing some kind of indicator. The CPU was not turning on but we can see the Power LED in Blinking Amber mode.
Upon investigation, we found the following website where a complete reference guide has been published for various Power LED Indicators and Beeps for different Dell OptiPlex Models.

We used one of the method according to blinking state of our PC and the problem was resolved.
We disconnected the Power Cord and drained the flea Power by holding the Power Button for a few seconds to clear "EC internal Failure
Generic catch-all for ungrateful EC code flow errors".
This method worked great and the PC was back to its original Power On state.
