how to fix screen from timing out every 30 seconds from lack of activity?

Hi, I'm Rodrigo and I will help you.
This can be adjusted on Power settings. Open the Start Menu > Settings > System > Power & Battery > Screen, sleep and hibernation timeouts.

To adjust the screen timeout settings on your Windows device, you can follow these steps:

1. Open Power Options: Go to the Control Panel and select Power Options.
2. Change Plan Settings: Click on Change plan settings next to your selected power plan.
3. Adjust Display Settings: Under the Turn off the display section, you can set the time for both On battery and Plugged in options to your preferred duration.
4. Save Changes: Make sure to save the changes after adjusting the settings.

If you are using a Windows 365 Link device, you can also manage screen timeout settings through Microsoft Intune by creating a policy that specifies the timeout duration. This can be done by navigating to the Intune admin center and configuring the appropriate settings under Devices > Configuration.

For specific configurations related to locked screens, you can use the powercfg.exe utility to set the timeout for when the PC is locked. This involves running commands in an administrative command prompt to adjust the timeout settings for both unlocked and locked states.
