Tengo un programa de duplicación de teléfono ( scrcpy
) y configuro mi computadora portátil para que se duerma después de 10 minutos. Lo uso principalmente para ver televisión en vivo, pero la computadora portátil se apaga mientras está funcionando. Después de leer en la web, intenté usarlo powercfg -requestsoverride
para ese programa, pero no parece funcionar. ¿Que se supone que haga?
EDITAR:Estoy usando Windows 10 por cierto.

Mantener pantalla encendida- Ejecuta un programa que impide dormir o que la pantalla se apague mientras se ejecuta el programa.
Esto utiliza los compiladores incorporados en Windows 10 (y lo han sido desde Windows Vista); hay tres compiladores de VB.NET y tres compiladores de C#; simplemente copie cada archivo de texto en la misma carpeta y haga doble clic en el archivo por lotes para crear el programa.
Esto utiliza una llamada APIEstablecer estado de ejecución de hilo(https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-setthreadexecutionstate) que es cómo los programas le dicen a Windows que no duerma.

No es necesario compilar scripts vbs; esto se puede hacer mediante un script de Powershell, que acabo de publicar enGitHub(y por debajo).
Este script le permite pasar listas de procesos que desea monitorear para evitar que su sistema ( -requiresSystem
) o tanto el sistema como la pantalla ( -requiresDisplay
) entren en suspensión. Se puede evitar la suspensión de la pantalla si un proceso de la lista respectiva está enfocado o generalmente no está minimizado/oculto (depende del -focusOnly
parámetro). Se puede ejecutar una vez o indefinidamente ( -oneTime
) con una tasa de sondeo personalizable ( -pollingRate
).
Ejemplo de uso:
SnoozeGuard.ps1 -requiresDisplay "mstsc" -requiresSystem "handbrake" -focusOnly 0 -pollingRate 120 -oneTime 0

[string[]]$requiresSystem,

Proceso de lazotiene una función para evitar que la PC entre en suspensión cuando se ejecutan procesos específicos. A esto lo llama unPrevenir el sueñoregla, y se puede aplicar solo a la pantalla o a toda la PC. Internamente utiliza elEstablecer estado de ejecución de hiloAPI, llamada por su servicio 'Gobernador'.
