One S Power Issues

I am not sure which troubleshooting steps you have tried already, but we recommend trying what's mentioned here in case you haven't => Troubleshoot Xbox console unexpectedly turning off | Xbox Support

In case the issue persists after the troubleshooting steps, the next step would be to perform an offline update on your console. You can fond the steps to do so here => Perform an offline system update | Xbox Support

When you say you have done a hard reset do you mean the below steps?

Power down your Xbox One by holding the Xbox button for 10 seconds. Once powered down, hold the sync, eject, and Xbox button on your console until you hear two beeps (around 10 seconds). Release the buttons, and you’ll see a factory reset menu. If you have an Xbox One S without an eject button, the sync and Xbox button will work.
