Unplugging controller from PC turns on XBOX

Yes, this is a little annoying to me as well. I purchased an Xbox One controller to use with my PC, and the light is super annoying when plugged in. When I unplugged it from the USB cable, it flashed for a bit, but then stopped. I wonder if there's any
way to turn off the controller when it's unplugged from USB and on battery? Or does it automatically sleep when not connected to an Xbox system or PC?

Update. Controller stops working when I unplug it from charging with the xbox too.

Pulled the battery from the back of the controller and re-turned on.

Still nothing.

I have removed the batteries from my controllers , unplugged the the xbox overnight. I just turned itself on right now with with a controller light on

Ok, so the problem is solved now. Here are the steps I followed.

- Uninstalled Xbox Accesories App

- Uninstalled all Driver in the Device Manager related to "Xbox Controller" and "Xbox Wireless Adapter"

- Unplugged the Wireless Adapter

- Turn off Bluetooth

- Turn off the PC

- Reset the Xbox Series Controller pairing (Hold connect button for x seconds)

- Turn off Xbox Series Controller

- Boot the PC

- Insert the Wireless Adapter -> Drivers are installed automatically

- Turn on Xbox Series controller

- Succesfully paired with the Wireless Adapter!!

- Install Xbox Accesories App -> Controller recognized

- Turn on Bluetooth

Thanks for the answer, Kathy and sorry for the delay but life prevented me from answering earlier.

The fact that running a simple troubleshooting routine solved it points at a software issue so I don´t expect to have this problem again.

Hope this helps someone.

Have you tried unplugging the xbox completely from the outlet so it has no chance of turning on when trying to pair it to your pc?
