Use the power button to turn off the computer at Welcome screen

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you want to turn off computer at the Welcome screen using the power button.



Ideally, if no user has logged in to the computer, the computer will shut down by pressing the power button. However, I would suggest you to check the settings for power button. Refer the steps mentioned below and see if that helps:

1. Press Windows key + X, and select
   Power Options.
   
2. Click on Additional power settings.
   
3. Now, click on Choose what power button does from the left pane.
   
4. Click on Change settings that are currently unavailable.
   
5. Select Shut down from the drop down for
   When I press the power button.
   

If you are using Windows 10 Pro, you may also want to check the Group Policy Settings, refer the steps mentioned below:

1. Press Windows key + R, to open
   Run dialog box.
   
2. Type gpedit.msc and click on
   OK.
   
3. Navigate to Computer Configuration\Administrative Templates\System\Power Management\Button Settings.
   
4. On the right pane, double click on Select the Power button action (plugged in), click on
   Enabled and select Shutdown from the drop down for
   Power Button Action.
   
5. Repeat step 4 for Select the Power button action (on battery).
   
6. Restart the computer.
   

If a user has logged in to the computer and then logs off from the computer, the computer will shut down by pressing the power button. However, if a user is logged in to the computer and locks the computer using the
Windows key + L combination, the power button will not shutdown the computer. You will have to use the power button on the lock screen to shut down the computer.



If you do not see the shutdown button, please refer the article Shutdown:
Allow system to be shut down without having to log on.



If the issue persists, I would suggest you to provide a feedback in the
Feedback Hub. The Feedback hub lets you tell Microsoft
about any problems you run in to while using Windows 10 and send suggestions to help us improve your Windows experience.

Screen goes black if the power cord is connected

Hi Tony,

As the screen goes black I suggest you to refer the Microsoft article on
Troubleshoot black screen problems and check if it helps.

Troubleshooting black or blank screens in Windows - Microsoft Support

I also see that you are facing issues with the keyboard this might be due to the corruption of keyboard drivers. I suggest you to run the
hardware and devices troubleshooter and check if it helps.

Follow the below steps for the same.

Windows 10 has a built-in troubleshooter to check and fix issues with hardware and devices. I would suggest you to run this troubleshooter. Refer these steps:

• Press Windows key + X, select Control panel.
• Change the view by option on the top right to Large icons.
• Click on troubleshooting and click on the view all option on the left panel.
• Run the Hardware and devices troubleshooter.
• Restart your computer and check if the issue is resolved.

Hope this information is helpful. Please get back to us with the information required, if you need further assistance, we’ll be glad to assist you.
