Windows 10: How can I set the time to dim the screen with command prompt?

I included the question in the title already. Thanks for your utmost patience!

:)

 

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?

 

Installation media boots to command prompt

I've just booted from known working install media to see exactly what it does when booting. The sequence of events is...

1. Windows logo on a black screen
2. circling dots appear beneath the logo
3. light blue 'Please wait' screen with circling dots
4. a command prompt window (very briefly)
5. the initial Setup page appears

Do you see steps 1-3? If so, it appears you have stopped at step 4, suggesting that something on the disc cannot be read.

Does the disc boot properly in another machine? If so, try cleaning the laptop's drive lens then try booting from the disc again.

If not, make new install media with Microsoft's Media Creation Tool, either as a bootable USB, on an ISO that you can burn to another disc. At Step 8 in Option One of this tutorial you can choose between making a USB or an ISO.

Windows 10 - Sceen Dims Automatically

Hi John,

I realize that the screen dims automatically on the PC. I will try to help you with this issue.

You may run the Power troubleshooter and restart the computer to check if this helps.

• 
  Press “Windows key + X” and click on “Control Panel”.
  
• 
  Click on “Troubleshooting”.
  
• 
  Click on “View all” and select “Power”.
  

Follow the on-screen directions to run this troubleshooter completely. Once this is done, restart the computer and check the status.

Further you may also follow these steps to reset all default power plans to default settings:

• 
  Open a command prompt.
  
• 
  In the command prompt, type “powercfg –restoredefaultschemes” and press Enter.
  
• 
  Close the command prompt.
  

Remember to restart the computer to check if that helps.

Keep us updated to help you further.

Thank you.
