1. An unresponsive Xbox One usually involves an issue with the power supply. First, ensure the power cable is firmly inserted in the back of the console and that the plug is properly connected to an AC wall outlet. 

2. If all is in order there, next check the outlet itself, either with a digital multimeter or simply by connecting a different electrical device to the outlet and seeing if it works.

Once it becomes clear the Xbox One itself is the problem, it's time to try a power reset – the system's internal power supply might be at issue, and note that we are here discussing the Xbox One X and S consoles; we'll cover the original Xbox One in a moment.

Customized Cable

1. To do a power reset, disconnect the power cable from the rear of the console and wait a full ten seconds. Now, reconnect the cable, then press the Xbox button on the front of the system.

2. Wait 10 seconds, then reconnect the power supply to the wall, then the console to the power supply.
