I installed Windows 10 to my Dell notebook, since that I am not able to shut down the notebook.

When I go to: Start>Power>Shut down appears the “Shutting down“ then screen shuts down but the power button is still lighting and the fan is working as well.(Restart is working)

I tried to type various shutdown commands like: shutdown /s /f /t 0 to the Command Prompt.(First time worked, then no)

I disabled Turn on Fast Startup.

I updated all the drivers.

Is there any other method to shut down the computer?

Thank you for answers.
